Description

IMPROVED MEDICAL DEVICES FIELD [0001] The subject matter pertains to medical devices, including devices having. a composition, surface, or feature that exposes and/or delivers one or more anti-connexin agents, with or without one or more other therapeutic agents and/or wound healing agents to tissue and/or fluid with which they come into contact on use or application. BACKGROUND [0002] The following description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art, or relevant, to the presently described or claimed invention, or that any publication or document that is specifically or implicitly identified is prior art or a reference that may be used in evaluating patentability. All documents and other information referred to in this patent are incorporated herein by reference in their entirety. [0003] Over the past two decades, much research effort has been directed towards the development of medical devices and machines that are used in a wide variety of clinical settings to repair, maintain, or enhance vital physiological functions of a subject mammal. For example, devices such as catheters, prosthetic heart valves, pacemakers, pulse generators, cardiac defibrillators, arteriovenous shunts, and stents are used extensively in the treatment of cardiac and other diseases. Other examples of medical devices, including screws, anchors, plates, staples, tacks, joints and similar devices, for example, are used in orthopedic surgery. These implantable medical devices are made from a wide variety of materials, including, for example, metals, plastics, and various polymeric materials. Other orthopedic devices include implants, such as implants for hip, shoulder, elbow and knee replacements and surgeries, or craniomaxillofacial reconstruction, and implant coatings, as well devices used in arthroscopic and laproscopic procedures, including burrs, suture-passing instruments, arthroscopic shavers. Other examples of medical devices include ocular devices, such as implants, including intraocular lenses and glaucoma shunts. Still other devices include gastrointestinal implants. Other examples of medical devices include devices for endoscopy, hysteroscopy, cytoscopy, bronchoscopy, etc.

[0004] When medical devices, for example, implantable medical devices, are brought into contact with a subject, natural bodily processes can result in inflammation, swelling, hypercellularity or other aberrant cellular disposition, growth and/or proliferation, and/or tissue damage. For example, platelets may attach to the medical device which can result in further complications at the site of use or implantation such as, for example, thrombosis, leukocyte attachment, and/or neutrophil and/or macrophage migration that lead to inflammation and/or aberrant cellular growth. An example of such a process resulting from the contacting of a medical device with a subject is provided by the use of a catheter or stent, which can result in tissue damage and/or restenosis. Restenosis, the reclosure of a peripheral or coronary artery following trauma to that artery generally caused by efforts to open a stenosed or occluded portion of the artery, and resulting trauma may be caused by, for example, balloon dilation, ablation, atherectomy or laser treatment of the artery. For example, balloon arterial injury reportedly results in endothelial denudation and subsequent regrowth of dysfunctional endothelium that may contribute to the local smooth muscle cell proliferation and extracellular matrix production that result in reocclusion of the arterial lumen. Restenosis has been reported to occur in as many as 50% of patients undergoing such angioplasty procedures. Restenosis is believed to be a natural healing process in reaction to the injury of the arterior wall caused by such angioplasty procedures. The healing process begins with the thrombotic mechanism at the site of the injury. The final steps of the healing process can be intimal hyperplasia, the uncontrolled migration and proliferation of medial smooth muscle cells, combined with their extracellular matrix production, until the artery is again stenosed or occluded. [0005] In humans and other mammals wound injury triggers an organized complex cascade of cellular and biochemical events that will in most cases result in a healed wound. An ideally healed wound is one that restores normal anatomical structure, function, and appearance at the cellular, tissue, organ, and organism levels. Wound healing, whether initiated by trauma, microbes or foreign materials, proceeds via a complex process encompassing a number of overlapping phases, including inflammation, epithelialization, angiogenesis and matrix deposition. Normally, these processes lead to a mature wound and a certain degree of scar formation. Although inflammation and repair mostly occur along a prescribed course, the sensitivity of the process is dependent on the balance of a variety of wound healing modulating factors, including for example, a network of regulatory cytokines and growth factors. [0006] Despite advances in the understanding of the principles underlying the wound healing process, there remains a significant unmet need in suitable therapeutic options for wound 2 care, including delayed or compromised wound healing of wounds such as chronic wounds, as well as swelling, inflammation, epithelialization rates and scarring associated with these and other wounds, including acute and subacute wounds. [0007] Gap junctions are cell membrane structures that facilitate direct cell-cell communication. A gap junction channel is formed of two connexons (hemichannels), each composed of six connexin subunits. Each hexameric connexon docks with a connexon in the opposing membrane to form a single gap junction. Gap junction channels are reported to be found throughout the body. Tissue such as the corneal epithelium, for example, has six to eight cell layers, yet is reported to expresses different gap junction channels in different layers with connexin 43 in the basal layer and connexin 26 from the basal to middle wing cell layers. In general, connexins are a family of proteins, commonly named according to their molecular weight or classified on a phylogenetic basis into alpha, beta, and gamma subclasses. At least 20 human and 19 murine isoforms have been identified. Different tissues and cell types are reported to have characteristic patterns of connexin protein expression and tissues such as cornea have been shown to alter connexin protein expression pattern following injury or transplantation (Qui, C. et al., (2003) Current Biology, 13:1967-1703; Brander et al., (2004), J. Invest Dermatol. 122:1310-20). [0008] It has been reported that abnormal connexin function may be linked to certain disease states (e.g. heart diseases) (A. C. de Carvalho, et al., J Cardiovasc Electrophysiol 1994, 5 686). In certain connexin proteins, alterations in the turnover and trafficking properties may be induced by the addition exogenous agents which may affect the level of gap junctional intercellular communication (Darrow, B. J., et al. (1995). Circ Res 76: 381; Lin R, et al. (2001) J Cell Biol 154(4):815). Antisense technology has been reported for the modulation of the expression for genes implicated in viral, fungal and metabolic diseases. See, e.g., U.S. Pat. No. 5,166,195, (oligonucleotide inhibitors of HIV), U.S. Pat. No. 5,004,810 (oligomers for hybridizing to herpes simplex virus Vmw65 mRNA and inhibiting replication). See also U.S. Pat. No. 7,098,190 to Becker et al. (formulations comprising antisense nucleotides to connexins). See also Becker and Green PCT/US06/04131 ("Anti-connexin compounds and uses thereof"). [0009] There is a need for medical devices that will aid in ameliorating tissue damage and/or enhancing tissue repair and/or limiting or inhibiting complications associated with using or implanting medical devices in a subject, such as for example, inflammation, restenosis and so on. It would be desirable to provide a medical device that aids in prevention, amelioration or treatment of damaged tissue and/or inflammation, and/or the enhancement of tissue repair, as 3 well as swelling, hypercellularity or other aberrant cellular disposition, growth and/or proliferation, and/or tissue damage.

DETAILED DESCRIPTION Definitions [0025] Before further describing the inventions in general and in terms of various nonlimiting specific embodiments, certain terms used in the context of the describing the invention are set forth. Unless indicated otherwise, the following terms have the following meanings when used herein and in the appended claims. Those terms that are not defined below or elsewhere in the specification shall have their art-recognized meaning. [0026] As used herein, "subject" refers to any animal classified as a mammal, including humans, domestic and farm animals, and zoo, sports, or pet animals, such as dogs, horses, cats, sheep, pigs, cows, etc. The preferred subject is a human. [0027] As used herein, "mammal" refers to any animal classified as a mammal, including humans, domestic and farm animals, and zoo, sports, or pet animals, such as dogs, horses, cats, 7 sheep, pigs, cows, etc. The preferred mammal herein is a human, including adults, children, and the elderly. [0028] As used herein, a "disorder" is any disorder, disease, or condition that would benefit from an agent that reduces damage associated with the use or implantation of a medical device. Disorders include, but are not limited to, damage to tissue (including, e.g., heart, liver, kidney, CNS (including brain), joint, gastrointestinal tissue) and vascular damage. [0029] As used herein, "pharmaceutically acceptable salts" refers to salts prepared from pharmaceutically acceptable non-toxic bases or acids including inorganic or organic bases and inorganic or organic acids the like. When the anti-connexin agent compound is basic, salts may be prepared from pharmaceutically acceptable non-toxic acids, including inorganic and organic acids. Such acids include acetic, benzenesulfonic, benzoic, camphorsulfonic, citric, ethanesulfonic, fumaric, gluconic, glutamic, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, mandelic, methanesulfonic, mucic, nitric, pamoic, pantothenic, phosphoric, succinic, sulfuric, tartaric, p-toluenesulfonic acid, and the like [0030] As used herein, "preventing" or "prevention" means preventing in whole or in part, ameliorating or controlling in whole or in part, or reducing, decreasing, lessening or retarding in whole or in part. [0031] The term "therapeutically effective amount" or "effective amount" means the amount of the subject compound that will elicit a desired response, for example, a biological or medical result or response of a tissue, system, animal or human that is sought, for example, by a researcher, veterinarian, medical doctor, or other clinician. That result can be alleviation of the signs, symptoms, or causes of a disease or disorder or condition, or any other desired alteration of a biological system. In the present invention, the result will typically involve, for example, the prevention, decrease, or reversal of tissue injury or damage, including inflammation, in whole or in part, associated with the use or implantation (temporary or permanent) of a medical device. The result will also typically involve the prevention, decrease, or reversal of inflammation. [0032] As used herein, the term "treatment" or "treating" refers to both therapeutic treatment and prophylactic or preventative measures. Prevention or prophylaxis may be in whole or in part. [0033] The term "damage associated with the use or implantation of a medical device" refers to damage or injury to tissue resulting from the insertion, presence, manipulation or removal of a medical device. "Damage associated with the use or implantation of a medical device" may be evidenced by one or more conditions, including an inflammatory response, a 8 proliferative response including neointimal proliferation, cellular proliferation, removal of endothelium and damage to smooth muscle cells, stenosis or restenosis following angioplasty or insertion and removal of a medical device, neointimal hyperplasia leading to stenosis or restenosis, platelet adhesion restenosis, and other inflammatory processes which are associated with implantation, use and removal of a medical device, including swelling. [0034] The terms "peptidomimetic" and "mimetic" include naturally occurring and synthetic chemical compounds that may have substantially the same structural and functional characteristics of protein regions which they mimic. In the case of connexins, these may mimic, for example, the extracellular loops of opposing connexins involved in connexon-connexon docking and cell-cell channel formation, and/or the extracellular loops of hemichannel connexins. [0035] As used herein, the term "peptide analogs" refer to the compounds with properties analogous to those of the template peptide and can be non-peptide drugs. "Peptidomimetics" (also known as peptide mimetics) which include peptide-based compounds, also include such non-peptide based compounds such as peptide analogs. Peptidomimetics that are structurally similar to therapeutically useful peptides can be used to produce an equivalent or enhanced therapeutic or prophylactic effect. Generally, peptidomimetics are structural or functional mimics (e.g. identical or similar) to a paradigm polypeptide (i.e., a polypeptide that has a biological or pharmacological function or activity), but can also have one or more peptide linkages optionally replaced by a linkage selected from the group consisting of, for example, CH 2 NH-, -CH 2 S-, -CH 2

-CH

2 -, - CH=CH- (cis and trans), -COCH 2 -, -CH(OH)CH 2 -, and -CH 2

SO

. The mimetic can be either entirely composed of natural amino acids, synthetic chemical compounds, non-natural analogues of amino acids, or, is a chimeric molecule of partly natural peptide amino acids and partly non-natural analogs of amino acids. The mimetic can also comprise any amount of natural amino acid conservative substitutions as long as such substitutions also do not substantially alter mimetic activity. In the case of connexins, these can mimic, for example, the extracellular loops of opposing connexins involved in connexon connexon docking and cell-cell channel formation. For example, a mimetic composition can be useful as a gap junction modulating agent if it is capable of down-regulating biological actions or activities of connexons, such as, for example, preventing the docking of connexons to form gap junction-mediated cell-cell communications, or preventing the opening of connexons to expose the cell cytoplasm to the extracellular millieu. Peptidomimetics encompass those described herein, as well as those as may be known in the art, whether now known or later developed. 9 [0036] The term "composition" is intended to encompass a product comprising one or more ingredients. [0037] In general, the terms "modulator" and "modulation" of gap junction activity, as used herein in its various forms, refers to inhibition in whole or in part of the action or activity of a gap junction or a hemichannel and may function as gap junction modulating agents. [0038] In general, the term "protein" refers to any polymer of two or more individual amino acids (whether or not naturally occurring) linked via peptide bonds, as occur when the carboxyl carbon atom of the carboxylic acid group bonded to the alpha-carbon of one amino acid (or amino acid residue) becomes covalently bound to the amino nitrogen atom of the amino group bonded to the alpha-carbon of an adjacent amino acid. These peptide bond linkages, and the atoms comprising them (i.e., alpha-carbon atoms, carboxyl carbon atoms (and their substituent oxygen atoms);,and amino nitrogen atoms (and their substituent hydrogen atoms)) form the "polypeptide backbone" of the protein. In addition, as used herein, the term "protein" is understood to include the terms "polypeptide" and "peptide" (which, at times, may be used interchangeably herein). Similarly, protein fragments, analogs, derivatives, and variants are may be referred to herein as "proteins," and shall be deemed to be a "protein" unless otherwise indicated. The term "fragment" of a protein refers to a polypeptide comprising fewer than all of the amino acid residues of the protein. A "domain" of a protein is also a fragment, and comprises the amino acid residues of the protein often required to confer activity or function. [0039] As used herein, it is to be understood that reference to a particular connexin is a reference to all species variants thereof, even if their molecular weights are different. Thus, for example, a reference to "connexin 43" means not only human connexin 43 but to the analogous connexin in each other species, no matter whether they are also 43Kd. Similarly, reference to a non-human "connexin 43" is a reference to the connexin 43 analog or variant in that species. Thus, for example, reference to "horse connexin 43" is a reference to the relevant analog or variant of human connexin 43 in horse even if it does not have a 43Kd molecular weight. Anti-Connexin Agents [0040] Anti-connexin agents of the invention described herein are capable of modulating or affecting the transport of molecules into and out of cells (e.g., blocking or inhibiting or downregulating). Thus certain anti-connexin agents described herein modulate cellular communication (e.g., cell to cell). Certain anti-connexin agents modulate or effect transmission of molecules between the cell cytoplasm and the periplasmic or extracellular space. Such anti connexin agents are generally targeted to connexins and/or connexin hemichannels (connexons) 10 or to gap junctions themselves. Hemichannels and resulting gap junctions that comprise connexins are independently involved in the release or exchange of small molecules between the cell cytoplasm and an extracellular space or tissue in the case of open hemichannels, and between the cytoplasm of adjoining cell in the case of open gap junctions. Thus, an anti-connexin agents provided herein may directly or indirectly reduce coupling and communication between cells or reduce or block communication (or the transmission of molecules) between a cell and extracellular space or tissue, and the modulation of transport of molecules from a cell into an extracellular space or tissue (or from an extracellular space or tissue into a cell) or between adjoining cells is within the scope of anti-connexin agents and embodiments of the invention. [0041] Any anti-connexin agent that is capable of eliciting a desired inhibition of the passage (e.g. transport) of molecules through a gap junction or connexin hemichannel may be used in embodiments of the invention. Any anti-connexin agents that modulates the passage of molecules through a gap junction or connexin hemichannel are also provided in particular embodiments (e.g., those that modulate, block or lessen the passage of molecules from the cytoplasm of a cell into an extracellular space or adjoining cell cytoplasm). Such anti-connexin agents may modulate the passage of molecules through a gap junction or connexin hemichannel with or without gap junction uncoupling (blocking the transport of molecules through gap junctions). Such compounds include, for example, proteins and polypeptides, polynucleotides, and other organic compounds, and they may, for example block the function or expression of a gap junction or a hemichannel in whole or in part, or downregulate the production of a connexin in whole or in part. Certain gap junction inhibitors are listed in Evans, W.H. and Boitano, S. Biochem. Soc. Trans. 29: 606-612 (2001). [0042] Certain anti-connexin agents provide downregulation or inhibition of connexin expression (for example, by downregulation of mRNA transcription or translation) or otherwise decrease or inhibit the activity of a connexin protein, a connexin hemichannel or a gap junction. In the case of downregulation, this will have the effect of reducing direct cell-cell communication by gap junctions, or exposure of cell cytoplasm to the extracellular space by hemichannels, at the site at which connexin expression is downregulated. [0043] Examples of anti-connexin agents include agents that decrease or inhibit expression or function of connexin mRNA and/or protein or that decrease activity, expression or formation of a connexin, a connexin hemichannel or a gap junction. Anti-connexin agents include anti connexin polynucleotides, such as antisense polynucleotides and other polynucleotides (such as polynucleotides having siRNA or ribozyme functionalities), as well as antibodies and binding 11 fragments thereof, and peptides and polypeptides, including peptidomimetics and peptide analogs that modulate hemichannel or gap junction activity or function. Anti-Connexin Polynucleotides [0044] Anti-connexin polynucleotides include connexin antisense polynucleotides as well as polynucleotides which have functionalities which enable them to downregulate connexin expression. Other suitable anti-connexin polynucleotides include RNAi polynucleotides and siRNA polynucleotides. [0045] Synthesis of antisense polynucleotides and other anti-connexin polynucleotides such as RNAi, siRNA, and ribozyme polynucleotides as well as polynucleotides having modified and mixed backbones is known to those of skill in the art. See e.g. Stein C.A. and Krieg A.M. (eds), Applied Antisense Oligonucleotide Technology, 1998 (Wiley-Liss). Methods of synthesizing antibodies and binding fragments as well as peptides and polypeptides, including peptidomimetics and peptide analogs are known to those of skill in the art. See e.g. Lihu Yang et al., Proc. NatL. Acad. Sci. US.A., 1; 95(18): 10836-10841 (Sept 1 1998); Harlow and Lane (1988) "Antibodies: A Laboratory Manuel" Cold Spring Harbor Publications, New York; Harlow and Lane (1999) "Using Antibodies" A Laboratory Manuel, Cold Spring Harbor Publications, New York. [0046] According to one aspect, the downregulation of connexin expression may be based generally upon the antisense approach using antisense polynucleotides (such as DNA or RNA polynucleotides), and more particularly upon the use of antisense oligodeoxynucleotides (ODN). These polynucleotides (e.g., ODN) target the connexin protein (s) to be downregulated. Typically the polynucleotides are single stranded, but may be double stranded. [0047] The antisense polynucleotide may inhibit transcription and/or translation of a connexin. Preferably the polynucleotide is a specific inhibitor of transcription and/or translation from the connexin gene or mRNA, and does not inhibit transcription and/or translation from other genes or mRNAs. The product may bind to the connexin gene or mRNA either (i) 5' to the coding sequence, and/or (ii) to the coding sequence, and/or (iii) 3' to the coding sequence. [0048] The antisense polynucleotide is generally antisense to a connexin mRNA. Such a polynucleotide may be capable of hybridizing to the connexin mRNA and may thus inhibit the expression of connexin by interfering with one or more aspects of connexin mRNA metabolism including transcription, mRNA processing, mRNA transport from the nucleus, translation or mRNA degradation. The antisense polynucleotide typically hybridizes to the connexin mRNA to 12 form a duplex which can cause direct inhibition of translation and/or destabilization of the mRNA. Such a duplex may be susceptible to degradation by nucleases. [0049] The antisense polynucleotide may hybridize to all or part of the connexin mRNA. Typically the antisense polynucleotide hybridizes to the ribosome binding region or the coding region of the connexin mRNA. The polynucleotide may be complementary to all of or a region of the connexin mRNA. For example, the polynucleotide may be the exact complement of all or a part of connexin mRNA. However, absolute complementarity is not required and polynucleotides which have sufficient complementarity to form a duplex having a melting temperature of greater than about 20*C, 30*C or 40"C under physiological conditions are particularly suitable for use in the present invention. [0050] Thus the polynucleotide is typically a homologue of a sequence complementary to the mRNA. The polynucleotide may be a polynucleotide which hybridizes to the connexin mRNA under conditions of medium to high stringency such as 0.03M sodium chloride and 0.03M sodium citrate at from about 50'C to about 60*C. [0051] For certain aspects, suitable polynucleotides are typically from about 6 to 40 nucleotides in length. Preferably a polynucleotide may be from about 12 to about 35 nucleotides in length, or alternatively from about 12 to about 20 nucleotides in length or more preferably from about 18 to about 32 nucleotides in length. According to an alternative aspect, the polynucleotide may be at least about 40, for example at least about 60 or at least about 80, nucleotides in length and up to about 100, about 200, about 300, about 400, about 500, about 1000, about 2000 or about 3000 or more nucleotides in length. [0052] The connexin protein or proteins targeted by the polynucleotide will be dependent upon the site at which downregulation is to be effected. This reflects the non-uniform make-up of gap junction(s) at different sites throughout the body in terms of connexin sub-unit composition. The connexin is a connexin that naturally occurs in a human or animal in one aspect or naturally occurs in the tissue in which connexin expression or activity is to be decreased. The connexin gene (including coding sequence) generally has homology with the coding sequence of one or more of the specific connexins mentioned herein, such as homology with the connexin 43 coding sequence shown in Table 8. The connexin is typically an a or 13 connexin. Preferably the connexin is an a connexin and is expressed in the tissue to be treated. [0053] Some connexin proteins are however more ubiquitous than others in terms of distribution in tissue. One of the most widespread is connexin 43. Polynucleotides targeted to 13 connexin 43 are particularly suitable for use in the present invention. In other aspects other connexins are targeted. [0054] Anti-connexin polynucleotides include connexin antisense polynucleotides as well as polynucleotides which have functionalities which enable them to downregulate connexin expression. Other suitable anti-connexin polynucleotides include RNAi polynucleotides and SiRNA polynucleotides. [0055] In one preferred aspect, the antisense polynucleotides are targeted to the mRNA of one connexin protein only. Most preferably, this connexin protein is connexin 43. In another aspect, connexin protein is connexin 26, 30, 31.1, 32, 36, 37, 40, or 45. In other aspects, the connexin protein is connexin 30.3, 31, 40.1, or 46.6. [0056] It is also contemplated that polynucleotides targeted to separate connexin proteins be used in combination (for example 1, 2, 3, 4 or more different connexins may be targeted). For example, polynucleotides targeted to connexin 43, and one or more other members of the connexin family (such'as connexin 26, 30, 30.3, 31.1, 32, 36, 37, 40, 40.1, 45, and 46.6) can be used in combination. [0057] Alternatively, the antisense polynucleotides may be part of compositions which may comprise polynucleotides to more than one connexin protein. Preferably, one of the connexin proteins to which polynucleotides are directed is connexin 43. Other connexin proteins to which oligodeoxynucleotides are directed may include, for example, connexins 26, 30, 30.3, 31.1, 32, 36, 37, 40, 40.1, 45, and 46.6. Suitable exemplary polynucleotides (and ODNs) directed to various connexins are set forth in Table 1. [0058] Individual antisense polynucleotides may be specific to a particular connexin, or may target 1, 2, 3 or more different connexins. Specific polynucleotides will generally target sequences in the connexin gene or mRNA which are not conserved between connexins, whereas non-specific polynucleotides will target conserved sequences for various connexins. [0059] The polynucleotides for use in the invention may suitably be unmodified phosphodiester oligomers. Such oligodeoxynucleotides may vary in length. A 30 mer polynucleotide has been found to be particularly suitable. [0060] Many aspects of the invention are described with reference to oligodeoxynucleotides. However it is understood that other suitable polynucleotides (such as RNA polynucleotides) may be used in these aspects. [0061] The antisense polynucleotides may be chemically modified. This may enhance their resistance to nucleases and may enhance' their ability to enter cells. For example, 14 phosphorothioate oligonucleotides may be used. Other deoxynucleotide analogs include methylphosphonates, phosphoramidates, phosphorodithioates, N3'P5'-phosphoramidates and oligoribonucleotide phosphorothioates and their 2'-O-alkyl analogs and 2'-0 methylribonucleotide methylphosphonates. Alternatively mixed backbone oligonucleotides ("MBOs") may be used. MBOs contain segments of phosphothioate oligodeoxynucleotides and appropriately placed segments of modified oligodeoxy-or oligoribonucleotides. MBOs have segments of phosphorothioate linkages and other segments of other modified oligonucleotides, such as methylphosphonate, which is non-ionic, and very resistant to nucleases or 2'-0 alkyloligoribonucleotides. Methods of preparing modified backbone and mixed backbone oligonucleotides are known in the art. [0062] The precise sequence of the antisense polynucleotide used in the invention will depend upon the target connexin protein. In one embodiment, suitable connexin antisense polynucleotides can include polynucleotides such as oligodeoxynucleotides selected from the following sequences set forth in Table 1: TABLE 1 5' GTA ATT GCG GCA AGA AGA ATT GTT TCT GTC 3' (connexin 43) (SEQ.ID.NO:1) 5' GTA ATT GCG GCA GGA GGA ATT GTT TCT GTC 3' (connexin 43) (SEQ.ID.NO:2) 5' GGC AAG AGA CAC CAA AGA CAC TAC CAG CAT (connexin 43) (SEQ.LD.NO:3) 3' 5' TCC TGA GCA ATA CCT AAC GAA CAA ATA 3' (connexin 26) (SEQ.ID.NO:4) 5' CAT CTC CTT GGT GCT CAA CC 3' (connexin 37) (SEQ.ID.NO:5) 5' CTG AAG TCG ACT TGG CTT GG 3' (connexin 37) (SEQ.ID.NO:6) 5' CTC AGA TAG TGG CCA GAA TGC 3' (connexin 30) (SEQ.ID.NO:7) 5' TTG TCC AGG TGA CTC CAA GG 3' (connexin 30) (SEQ.ID.NO:8) 5' CGT CCG AGC CCA GAA AGA TGA GGT C 3' (connexin (SEQ.ID.NO:9) 31.1) 5' AGA GGC GCA CGT GAG ACA C 3' (connexin (SEQ.ID.NO:10) 15 31.1) 5' TGA AGA CAA TGA AGA TGT T 3' (connexin (SEQ.LD.NO:11) 31.1) 5' TTT CTT TTC TAT GTG CTG TTG GTG A 3' (connexin 32) (SEQ.ID.NO:12) [0063] Suitable polynucleotides for the preparation of the combined polynucleotide compositions described herein include for example, polynucleotides to Connexin Cx43 and polynucleotides for connexins 26, 30, 31.1, 32 and 37 as described in Table I above. [0064] Although the precise sequence of the antisense polynucleotide used in the invention will depend upon the target connexin protein, for connexin 43, antisense polynucleotides having the following sequences have been found to be particularly suitable: GTA ATT GCG GCA AGA AGA ATT GTT TCT GTC (SEQ.ID.NO:l); GTA ATT GCG GCA GGA GGA ATT GTT TCT GTC (SEQ.ID.NO:2); and GGC AAG AGA CAC CAA AGA CAC TAC CAG CAT (SEQ.ID.NO:3). [0065] For example, suitable antisense polynucleotides for connexins 26, 31.1 and 32 have the following sequences: 5' TCC TGA GCA ATA CCT AAC GAA CAA ATA (connexin 26) (SEQ.ID.NO:4); 5' CGT CCG AGC CCA GAA AGA TGA GGT C (connexin 31.1) (SEQ.ID.NO:9); and 5' TTT CTT TTC TAT GTG CTG TTG GTG A (connexin 32) (SEQ.ID.NO:12). [0066] Other connexin antisense polynucleotide sequences useful according to the methods of the present invention include: 5' CAT CTC CTT GGT GCT CAA CC 3' (connexin 37) (SEQ.ID.NO: 5); 5' CTG AAG TCG ACT TGG CTT GG 3' (connexin 37) (SEQ.ID.NO: 6); 5' CTC AGA TAG TGG CCA GAA TGC 3' (conncxin 30) (SEQ.ID.NO: 7); 5' TTG TCC AGG TGA CTC CAA GG 3' (connexin 30) (SEQ.ID.NO: 8); 5' AGA GGC GCA CGT GAG ACA C 3' (connexin 31.1) (SEQ.ID.NO: 10); and 5' TGA AGA CAA TGA AGA TGT T 3' (connexin 31.1) (SEQ.ID.NO: 11). [0067] Polynucleotides, including ODN's, directed to connexin proteins can be selected in terms of their nucleotide sequence by any convenient, and conventional, approach. For example, 16 the computer programs MacVector and OligoTech (from Oligos etc. Eugene, Oregon, USA) can be used. Once selected, the ODN's can be synthesized using a DNA synthesizer. Polynucleotide Homologues [0068] Homology and homologues are discussed herein (for example, the polynucleotide may be a homologue of a complement to a sequence in connexin mRNA). Such a polynucleotide typically has at least about 70% homology, preferably at least about 80%, at least about 90%, at least about 95%, at least about 97% or at least about 99% homology with the relevant sequence, for example over a region of at least about 15, at least about 20, at least about 40,'at least about 100 more contiguous nucleotides (of the homologous sequence). [0069] Homology may be calculated based on any method in the art. For example the UWGCG Package provides the BESTFIT program which can be used to calculate homology (for example used on its default settings) (Devereux et al (1984) Nucleic Acids Research 12, p387 395). The PILEUP and BLAST algorithms can be used to calculate homology or line up sequences (typically on their default settings), for example as described in Altschul S. F. (1993) J Mol Evol 36: 290-300; Altschul, S, F et al (1990) J Mol Biol 215: 403-10. [0070] Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information (http://www.ncbi.nlm.nih.gov/). This algorithm involves first identifying high scoring sequence pair (HSPs) by identifying short words of length W in the query sequence that either match or satisfy some positive-valued threshold score T when aligned with a word of the same length in a database sequence. T is referred to as the neighbourhood word score threshold (Altschul et al, supra). These initial neighbourhood word hits act as seeds for initiating searches to find HSPs containing them. The word hits are extended in both directions along each sequence for as far as the cumulative alignment score can be .increased. Extensions for the word hits in each direction are halted when: the cumulative alignment score falls off by the quantity X from its maximum achieved value; the cumulative score goes to zero or below, due to the accumulation of one or more negative-scoring residue alignments; or the end of either sequence is reached. [0071] The BLAST algorithm parameters W, T and X determine the sensitivity and speed of the alignment. The BLAST program uses as defaults a word length (W), the BLOSUM62 scoring matrix (see Henikoff and Henikoff (1992) Proc. Natl. Acad. Sci. USA 89: 10915-10919) alignments (B) of 50, expectation (E) of 10, M=5, N=4, and a comparison of both strands. [0072] The BLAST algorithm performs a statistical analysis of the similarity between two sequences; see e.g., Karlin and Altschul (1993) Proc. Natl. Acad. Sci. USA 90: 5873-5787. One 17 measure of similarity provided by the BLAST algorithm is the smallest sum probability (P(N)), which provides an indication of the probability by which a match between two nucleotide or amino acid sequences would occur by chance. For example, a sequence is considered similar to another sequence if the smallest sum probability in comparison of the first sequence to a second sequence is less than about 1, preferably less than about 0.1, more preferably less than about 0.01, and most preferably less than about 0.001. [0073] The homologous sequence typically differs from the relevant sequence by at least about (or by no more than about) 2, 5, 10, 15, 20 more mutations (which may be substitutions, deletions or insertions). These mutations may be measured across any of the regions mentioned above in relation to calculating homology. [0074] The homologous sequence typically hybridizes selectively to the original sequence at a level significantly above background. Selective hybridization is typically achieved using conditions of medium to high stringency (for example 0.03M sodium chloride and 0.03M sodium citrate at from about 50*C to about 60*C). However, such hybridization may be carried out under any suitable conditions known in the art (see Sambrook et al. (1989), Molecular Cloning: A Laboratory Manual). For example, if high stringency is required, suitable conditions include 0.2 x SSC at 60*C. If lower stringency is required, suitable conditions include 2 x SSC at 60 0 C. Peptide and Polypeptide Anti-Connexin Agents [0075] Binding proteins, including peptides, peptidomimetics, antibodies, antibody fragments, and the like, are also suitable modulators of gap junctions and hemichannels. [0076] Binding proteins include, for example, monoclonal antibodies, polyclonal antibodies, antibody fragments (including, for example, Fab, F(ab') 2 and Fv fragments; single chain antibodies; single chain Fvs; and single chain binding molecules such as those comprising, for example, a binding domain, hinge, CH2 and CH3 domains, recombinant antibodies and antibody fragments which are capable of binding an antigenic determinant (i.e., that portion of a molecule, generally referred to as an epitope) that makes contact with a particular antibody or other binding molecule. These binding proteins, including antibodies, antibody fragments, and so on, may be chimeric or humanized or otherwise made to be less immunogenic in the subject to whom they are to be administered, and may be synthesized, produced recombinantly, or produced in expression libraries. Any binding molecule known in the art or later discovered is envisioned, such as those referenced herein and/or described in greater detail in the art. For example, binding proteins include not only antibodies, and the like, but also ligands, receptors, peptidomimetics, or 18 other binding fragments or molecules (for example, produced by phage display) that bind to a target (e.g. connexin, hemichannel, or associated molecules). [0077] Binding molecules will generally have a desired specificity, including but not limited to binding specificity, and desired affinity. Affinity, for example, may be a Ka of greater than or equal to about 104 M~', greater than or equal to about 106 M', greater than or equal to about 10 7 M', greater than or equal to about 108 M-. Affinities of even greater than about 108 M- are suitable, such as affinities equal to or greater than about 109 M-, about 1010 M', about 10" M- , and about 1012 M'. Affinities of binding proteins according to the present invention can be readily determined using conventional techniques, for example those described by Scatchard et al., 1949 Ann. N.Y Acad Sci. 51: 660. [0078] By using data obtained from hydropathy plots, it has been proposed that a connexin contains four-transmembrane-spanning regions and two short extra-cellular loops. The positioning of the first and second extracellular regions of connexin was further characterized by the reported production of anti-peptide antibodies used for immunolocalization of the corresponding epitopes on split gap junctions. Goodenough D.A. J Cell Biol 107: 1817-1824 (1988); Meyer R.A., J Cell Biol 119: 179-189 (1992). [0079] The extracellular domains of a hemichannel contributed by two adjacent cells "dock" with each other to form complete gap junction channels. Reagents that interfere with the interactions of these extracellular domains can impair cell-to-cell communication. Peptide inhibitors of gap junctions and hemichannels have been reported. See for example Berthoud, V.M. et al., Am J Physiol. Lung Cell Mol. Physiol. 279: L619 - L622 (2000); Evans, W.H. and Boitano, S. Biochem. Soc. Trans. 29: 606 - 612, and De Vriese A.S., et al. Kidney Int. 61: 177 185 (2001). Short peptides corresponding to sequences within the extracellular loops of connexins were said to inhibit intercellular communication. Boitano S. and Evans W. Am J Physiol Lung Cell Mol Physiol 279: L623-L630 (2000). The use of peptides as inhibitors of cell cell channel formation produced by connexin (Cx) 32 expressed in paired Xenopus oocytes has also been reported. Dahl G, et al., Biophys J 67: 1816-1822 (1994). Berthoud, V.M. and Seul, K.H., summarized some of these results. Am J., Physiol. Lung Cell Mol. Physiol. 279: L619 L622 (2000). [0080] Anti-connexin agents include peptides comprising an amino acid sequence corresponding to a transmembrane region (e.g Ist to 4t) of a connexin (e.g. connexin 45, 43, 26, 30, 31.1, and 37). Anti-connexin agents may comprise a peptide comprising an amino acid sequence corresponding to a portion of a transmembrane region of a connexin 45. Anti-connexin 19 agents include a peptide having an amino acid sequence that comprises about 5 to 20 contiguous amino acids of SEQ.ID.NO:13, a peptide having an amino acid sequence that comprises about 8 to 15 contiguous amino acids of SEQ.ID.NO:13, or a peptide having an amino acid sequence that comprises about 11 to 13 contiguous amino acids of SEQ.ID.NO:13. Other embodiments are directed to an anti-connexin agent that is a peptide having an amino acid sequence that comprises at least about 5, at least about 6, at least about 7, at least about 8, at least about 9, at least about 10, at least about 11, at least about 12, at least about 13, at least about 14, at least about 15, at least about 20, at least about 25, or at least about 30 contiguous amino acids of SEQ.ID.NO:13. In certain anti-connexin agents provided herein, the extracellular domains of connexin 45 corresponding to the amino acids at positions 46-75 and 199-228 of SEQ ID NO: 13 may be used to develop the particular peptide sequences. Certain peptides described herein have an amino acid sequence corresponding to the regions at positions 46-75 and 199-228 of SEQ.ID.NO: 13. The peptides need not have an amino acid sequence identical to those portions of SEQ.ID.NO: 13, and conservative amino acid changes may be made such that the peptides retain binding activity or functional activity. Alternatively, the peptide may target regions of the connexin protein other than the extracellular domains (e.g. the portions of SEQ.ID.NO:13 not corresponding to positions 46-75 and 199-228). [0081] Also, suitable anti-connexin agents comprise a peptide comprising an amino acid sequence corresponding to a portion of a transmembrane region of a connexin 43. Anti-connexin agents include peptides having an amino acid sequence that comprises about 5 to 20 contiguous amino acids of SEQ.ID.NO:14, peptides having an amino acid sequence that comprises about 8 to 15 contiguous amino acids of SEQ.ID.NO:14, or peptides having an amino acid sequence that comprises about 11 to 13 contiguous amino acids of SEQ.ID.NO:14. Other anti-connexin agents include a peptide having an amino acid sequence that comprises at least about 5, at least about 6, at least about 7, at least about 8, at least about 9, at least about 10, at least about 11, at least about 12, at least about 13, at least about 14, at least about 15, at least about 20, at least about 25, or at least about 30 contiguous amino acids of SEQ.ID.NO: 14. Other anti-connexin agents comprise the extracellular domains of connexin 43 corresponding to the amino acids at positions 37-76 and 178-208 of SEQ.ID.NO: 14. Anti-connexin agents include peptides described herein which have an amino acid sequence corresponding to the regions at positions 37-76 and 178-208 of SEQ.ID.NO: 14. The peptides need not have an amino acid sequence identical to those portions of SEQ.ID.NO: 14, and conservative amino acid changes may be made such that the peptides retain binding activity or functional activity. Alternatively, peptides may target regions of the 20 connexin protein other than the extracellular domains (e.g. the portions of SEQ.ID.NO:14 not corresponding to positions 37-76 and 178-208).

Exemplary conservative amino acid substitutions include for example the substitution of a nonpolar amino acid with another nonpolar amino acid, the substitution of an aromatic amino acid with another aromatic amino acid, the substitution of an aliphatic amino acid with another aliphatic amino acid, the substitution of a polar amino acid with another polar amino acid, the substitution of an acidic amino acid with another acidic amino acid, the substitution of a basic amino acid with another basic amino acid, and the substitution of an ionizable amino acid with another ionizable amino acid.

Such therapeutic agents may be prepared and formulated for inclusion in the medical devices of the present invention using techinques known to those in the art. [0096] In certain embodiments, one, two three, four, five or six therapeutic agents may be used in combination. Agents Useful for Wound Healing [0097] As used herein, agents useful for wound healing include stimulators, enhancers or positive mediators of the wound healing cascade which 1) promote or accelerate the natural wound healing process or 2) reduce effects associated with improper or delayed wound healing, which effects include, for example, adverse inflammation, epithelialization, angiogenesis and matrix deposition, and scarring and fibrosis. [0098] Positive mediators, enhancers and stimulators include for example, an agent which may stimulate, enhance, facilitate, or accelerate (i.e., agonize) the quantity, quality or efficacy of wound healing or the active wound healing process, or a wound healing-associated growth factor or cytokine at a wound site, or the activation of a wound healing-associated growth factor or cytokine receptor. Such agents may include a wound healing-associated growth factor or cytokine or a partially modified form of a wound healing-associated growth factor or cytokine, for example. A partially modified form of wound healing-associated growth factor or cytokine may, for example, have a longer half-life than the natural wound healing-associated growth factor or cytokine. Alternatively, it may be an inhibitor of wound healing-associated growth factor or cytokine metabolism. [0099] Partial modification of such an agent may be by way of addition, deletion or substitution of amino acid residues. A substitution may for example be a conserved substitution. Hence a partially modified molecule may be a homologue of the molecule from which it was derived. It may have at least about 40%, for example about 50, 60, 70, 80, 90 or 95%, homology with the molecule from which it is derived. 33 [00100] As used herein, agents useful for wound healing may include for example, wound healing-promoting or scar-reducing agents for wound treatment modalities now known in the art or later-developed; exemplary factors, agents or modalities including natural or synthetic growth factors, cytokines, or modulators thereof to promote wound healing, wound healing promoting bioengineered matrix, dressings bandages, and the like. Suitable examples may include, but not limited to 1) topical or dressing and related therapies and debriding agents (such as, for example, Santyl@ collagenase) and Iodosorb@ (cadexomer iodine); 2) antimicrobial agents, including systemic or topical creams or gels, including, for example, silver-containing agents such as SAGs (silver antimicrobial gels), (CollaGUARD(TM), Innocoll, Inc) (purified type-I collagen protein based dressing), CollaGUARD Ag (a collagen-based bioactive dressing impregnated with silver for infected wounds or wounds at risk of infection), DermaSIL(TM) (a collagen- synthetic foam composite dressing for deep and heavily exuding wounds); 3) cell therapy or bioengineered skin, skin substitutes, and skin equivalents, including, for example, Dermograft (3-dimensional matrix cultivation of human fibroblasts that secrete cytokines and growth factors), Apligraf@ (human keratinocytes and fibroblasts), Graftskin@ (bilayer of epidermal cells and fibroblasts that is histologically similar to normal skin and produces growth factors similar to those produced by normal skin), TransCyte (a Human Fibroblast Derived Temporary Skin Substitute) and Oasis® (an active biomaterial that comprises both growth factors and extracellular matrix components such as collagen, proteoglycans, and glycosaminoglycans); 4) cytokines, growth factors or hormones (both natural and synthetic) introduced to the wound to promote wound healing, including, for example, NGF, NT3, BDGF, integrins, plasmin, semaphoring, blood-derived growth factor, keratinocyte growth factor, tissue growth factor, TGF-alpha, TGF-beta, PDGF (one or more of the three subtypes may be used: AA, AB, and B), PDGF-BB, TGF-beta 3, factors that modulate the relative levels of TGFp3, TGFpl, and TGFp2 (e.g., Mannose-6-phosphate), sex steroids, including for example, estrogen, estradiol, or an estrogen receptor agonist selected from the group consisting of ethinyloestradiol, dienoestrol, mestranol, oestradiol, oestriol, a conjugated oestrogen, piperazine oestrone sulphate, stilboestrol, fosfesterol tetrasodium, polyestradiol phosphate, tibolone, a phytoestrogen, 17-beta-estradiol; thymic hormones such as Thymosin-beta-4, EGF, HB-EGF, fibroblast growth factors (e.g., FGF1, FGF2, FGF7), keratinocyte growth factor, TNF, interleukins family of inflammatory response modulators such as, for example, IL-10, IL-1, IL-2, IL-6, IL-8, and IL-10 and modulators thereof, INFs (INF alpha, -beta, and -delta); stimulators of activin or inhibin, and inhibitors of interferon gamma prostaglandin E2 (PGE2) and of mediators of the adenosine 3',5'-cyclic monophosphate (cAMP) 34 pathway; adenosine Al agonist, adenosine A2 agonist or 5) other agents useful for wound healing, including, for example, both natural or synthetic homologues, agonist and antagonist of VEGF, VEGFA, IGF; IGF-l, proinflammatory cytokines, GM-CSF, and leptins and 6) IGF-l and KGF cDNA, autologous platelet gel, hypochlorous acid (Sterilox@ lipoic acid, nitric oxide synthase3, matrix metalloproteinase 9 (MMP-9), CCT-ETA, alphavbeta6 integrin, growth factor primed fibroblasts and Decorin, silver containing wound dressings, XenadermTM, papain wound debriding agents, lactoferrin, substance P, collagen, and silver-ORC, placental alkaline phosphatase or placental growth factor, modulators of hedgehog signaling, modulators of cholesterol synthesis pathway, and APC (Activated Protein C), keratinocyte growth factor, TNF, Thromboxane A2, NGF, BMP bone morphogenetic protein, CTGF (connective tissue growth factor), wound healing chemokines, decorin, modulators of lactate induced neovascularization, cod liver oil, placental alkaline phosphatase or placental growth factor, and thymosin beta 4. In certain embodiments, one, two three, four, five or six agents useful for wound healing may be used in combination. [00101] It is to be understood that the agents useful for wound healing (including for example, growth factors and cytokines) above encompass all naturally occurring polymorphs (for example, polymorphs of the growth factors or cytokines). Also, functional fragments, chimeric proteins comprising one of said agents useful for wound healing or a functional fragment thereof, homologues obtained by analogous substitution of one or more amino acids of the wound healing agent, and species homologues are encompassed. It is contemplated that one or more agents useful for wound healing may be a product of recombinant DNA technology, and one or more agents useful for wound healing may be a product of transgenic technology. For example, platelet derived growth factor may be provided in the form of a recombinant PDGF or a gene therapy vector comprising a coding sequence for PDGF. [00102] A fragment or partially modified form thereof refers to a fragment or partially modified form of the wound healing agent which retains the biological or wound healing functionality of the factor, although it may of course have additional functionality. Partial modification may, for example, be by way of addition, deletion or substitution of amino acid residues. For example, a substitution may be a conserved substitution. Hence the partially modified molecules may be homologues of the wound healing agent. They may, for example, have at least about 40% homology with said factor. They may for example have at least about 50, 60, 70, 80, 90 or 95% homology with said factor. For example, in certain embodiments, IL-10 or a fragment or a partially modified form thereof may be administered at a concentration of 35 between about 1 [LM and about 10 pM. It may be administered at a concentration of between about 2.5 pM and about 5 pM. In certain other embodiments, IL-10 or a fragment or a partially modified form thereof may be administered immediately prior to wound healing, but may be effective if administered within about 7 days of wounding. It could be administered on at least two occasions. Gap Junction Modifying Agents [00103] Gap junction modifying agents, include agents that close or block gap junctions or otherwise prevent or decrease cell to cell communication via gap junctions. [00104] As used herein, "gap junction modifying agent" may broadly include those agents or compounds that prevent, decrease or modulate, in whole or in part, the activity, function, or formation of a hemichannel or a gap junction. [00105] In other embodiments, a gap junction modifying agent prevents or decreases, in whole or in part, the formation or activity of a hemichannel or a gap junction. [00106] In certain embodiments, a gap junction modifying agent induces closure, in whole or in part, of a hemichannel or a gap junction. In other embodiments, a gap junction modifying agent blocks, in whole or in part, a hemichannel or a gap junction. In certain embodiments, a gap junction modifying agent decreases or prevents, in whole or in part, the opening of a hemichannel or gap junction. [00107] In certain embodiments, said blocking or closure of a gap junction or hemichannel by a gap junction modifying agent can reduce or inhibit extracellular hemichannel communication by preventing or decreasing the flow of small molecules through an open channel to and from an extracellular or periplamic space. [00108] Gap junction modifying agents used for closing gap junctions (e.g. phosphorylating connexin 43 tyrosine residues) have been reported in U.S. Pat. No. 7,153,822 to Jensen et al., U.S. Pat. No. 7,250,397, and assorted patent publications. Exemplary gap junction modifying agents, also include peptides and peptidomimetics are reported in Green et al., W02006134494. See also Gourdie et al., see W02006069181, and Tudor et al., see W02003032964. [00109] As used herein, "gap junction phosphorylating agent" may include those agents or compounds capable of inducing phosphorylation on connexin amino acid residues in order to induce gap junction or hemichannel closure. Exemplary sites of phosphorylation include one or more of a tyrosine, serine or threonine residues on the connexin protein. In certain embodiments, modulation of phosphorylation may occur on one or more residues on one or more connexin proteins. Exemplary gap junction phosphorylating agents are well known in the art and may 36 include, for example, c-Src tyrosine kinase or other G protein-coupled receptor agonists. See Giepmans B, J. Biol. Chem., Vol. 276, Issue 11, 8544-8549, March 16, 2001. In one embodiment, modulation of phosphorylation on one or more of these residues impacts hemichannel function, particularly by closing the hemichannel. In another embodiment, modulation of phosphorylation on one or more of these residues impacts gap junction function, particularly by closing the gap junction. Gap junction phosphorylating agents that target the closure of connexin 43 gap junctions and hemichannels are preferred. Still other anti-connexin agents include connexin carboxy-terminal polypeptides. See Gourdie et al., W02006/069181. [00110] In certain another aspect, gap junction modifying agent may include, for example, aliphatic alcohols; octanol; heptanol; anesthetics (e.g. halothane), ethrane, fluothane, propofol and thiopental; anandamide; arylaminobenzoate (FFA: flufenamic acid and similar derivatives that are lipophilic); carbenoxolone; Chalcone: (2',5'- dihydroxychalcone); CHFs (Chlorohydroxyfuranones); CMCF (3-chloro-4-(chloromethyl)-5-hydroxy-2(5H)-furanone); dexamethasone; doxorubicin (and other anthraquinone derivatives); eicosanoid thromboxane A(2) (TXA(2)) mimetics; NO (nitric oxide); Fatty acids (e.g. arachidonic acid, oleic acid and lipoxygenase metabolites; Fenamates (flufenamic (FFA), niflumic (NFA) and meclofenamic acids (MFA)); Genistein; glycyrrhetinic acid (GA): 1 8a-glycyrrhetinic acid and 18-beta glycyrrhetinic acid, and derivatives thereof; lindane; lysophosphatidic acid; mefloquine; menadione; 2-Methyl-1,4-naphthoquinone, vitamin K(3); nafenopin; okadaic acid; oleamide; oleic acid; PH, gating by intracellular acidification; e.g. acidifying agents; polyunsaturated fatty acids; fatty acid GJIC inhibitors (e.g. oleic and arachidonic acids); quinidine; quinine; all trans retinoic acid; and tamoxifen. Medical Devices [00111] The term "medical device" refers to an instrument, apparatus, implement, machine, contrivance, implant, or other similar or related article, including a component part or accessory which is intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment or prevention of a disease, disorder or condition in humans or in other animals (particularly in mammals); is intended to affect the structure or any function of the body of a human or other animal; or is recognized in the official National Formulary or the United States Pharmacopoeia or any supplement to them. In particular, "medical device" includes a manufactured product which is used to cope with a disease, disorder or condition (particularly human diseases, disorders or conditions), such as by preventing, diagnosing, treating, alleviating and or monitoring disease, disorder or condition; care for injuries (particularly human injuries), 37 such as by diagnosing, treating, alleviating, monitoring or compensating for injuries; meet anatomical needs (particularly human anatomical needs), such as by investigating, replacing, modifying or supporting anatomical structures; maintain physiological functions (particularly human physiological functions), such as by investigating, replacing, modifying or supporting physiological functions; supporting or sustaining life (particularly human life); and controling conception (particularly human conception). [00112] The term "implantable medical device" refers to a medical device that is partly or totally inserted into the subject's body (such as the body of a human or other mammal) or a natural orifice thereof and is expected to stay there for an extended period of time (for example about 2, 5 7, 10, 14, or 30 days or more). Typically, surgical or medical procedures are used to insert or apply implantable medical devices, and surgical or medical procedures are used to remove them. [00113] The anti-connexin agents, compositions, and methods provided herein can be used in a variety of procedures that utilize of implants, medical and surgical devices, and the like. In one aspect, implants, surgical devices or stents, are coated with or otherwise constructed to contain and/or release any of the anti- connexin agents provided herein. Medical devices comprising an anti-connexin agent, may include, for example, stents, balloons, prosthetic heart valves, annuloplasty rings, ventricular assist devices, including left ventricular assist devices, right ventricular assist devices, and biventricular assist devices, grafts, shunts, sewing rings (including those having silicone or polyurethane inserts), polyester fabric encasements, medical leads, orthopedic plates, bone pins, bone substitutes, anchors, joints, screws, ophthalmic implants (including, for example, orbital implants, lens implants, corneal implants (including intrasomal corneal ring segments (INTACS)), and microchips), catheters, cannulae, pulse generators, cardiac defibrillators, arteriovenous shunts, pacemakers, sutures, suture anchors, staples, anastomosis devices, vertebral disks, hemostatic barriers, clamps, clips, vascular implants, tissue adhesives and sealants, tissue scaffolds, intraluminal devices, vascular supports as well as any devices used in connection with general orthopedic, hip replacement, CNS, ocular, gastrointestinal, and endoscopy procedures. [00114] Other examples include cardiovascular devices (e.g., implantable venous catheters, venous ports, tunneled venous catheters, chronic infusion lines or ports, including hepatic artery infusion catheters, pacemaker wires, implantable defibrillators); neurologic/neurosurgical devices (e.g., ventricular peritoneal shunts, ventricular atrial shunts, nerve stimulator devices, dural patches and implants to prevent epidural fibrosis post-laminectomy, devices for continuous 38 subarachnoid infusions); gastrointestinal devices (e.g., chronic indwelling catheters, feeding tubes, and shunts), splints for failed dacrocystalrhinostomy, implants for diabetic retinopathy; otolaryngology devices (e.g., ossicular implants, Eustachian tube splints or stents for glue ear or chronic otitis as an alternative to transtempanic drains); plastic surgery implants (e.g., prevention of fibrous contracture in response to gel- or saline-containing breast implants in the subpectoral or subglandular approaches or post-mastectomy, or chin implants), and orthopedic implants (e.g., cemented orthopedic prostheses). [00115] Examples of stents include intravascular and intraductal stents, and see also, for example, Pepine et al., "Coronary Artery Stents, JACC Vol. 28, No. 3, September 1996:782-94; D. Stoeckel, "A survey of stent designs," Min Invas Ther & Allied Technol 2002: 11(4) 137 147. Stents may also include, for example, balloon-expandable stents and self-expanding stents. Balloon-expandable stents include those of the sort available from a number of commercial suppliers, including Cordis Johnson & Johnson Interventional Systems, Medi-Tech, Cook, ACS, and Metronic. Self-expanding stents are typically composed, for example, from a shape memory alloy and are available from suppliers, such as Instent. In the case of stents, a balloon expandable stent is typically composed of a stainless steel framework or, in the case of self expanding stents, from nickel/titanium alloy. While typically stents are made of a metallic material -for strength purposes, polymeric or plastic materials may also be utilized in the stent construction. While it is preferred that the stent be coated in an expanded position, coating the stent in an unexpanded position is also contemplated. Exemplary coated balloons include, for example, coated balloons and coated balloon catheters, including inflatable and self inflatable coated balloons and balloon catheters. The inflatable coated balloon may be a non-dispensable balloon, for example, typically composed of polyethyleneterephthalate, or it may be an elastic balloon, for example, typically being composed of latex or silicone rubber. Preparation of Devices [00116] Implants and other surgical and medical devices may be coated with (or otherwise adapted to release) agents of the invention (e.g., anti-connexin agents and compositions) in a variety of manners, including for example: (a) by directly affixing to the implant or device an anti-connexin agent or composition (e.g., by either spraying the implant or device with a polymer/drug film, or by dipping the implant or device into a polymer/drug solution, or by other covalent or noncovalent means); (b) by coating the implant or device with a substance such as a hydrogel which will in turn absorb the anti-connexin composition (or anti-connexin factor above); (c) by interweaving anti-connexin composition coated thread (or the polymer itself 39 formed into a thread) into the implant or device; (d) by inserting the implant or device into a sleeve or mesh which is comprised of or coated with an anti-connexin composition; (e) constructing the implant or device itself with an anti- connexin agent or composition; or (f) by otherwise adapting the implant or device to release the anti-connexin agent, for example by providing multiple layers or other delivery vehicles, layers or other delivery vehicles with differing release characteristics, or by preparing a device with different parts or regions that include (by layers or otherwise) different compounds (with or without different release characteristics). Within preferred embodiments of the invention, the composition should firmly adhere to the implant or device during storage and at the time of insertion. The anti- connexin agent or composition should also preferably not degrade during storage, prior to insertion, or when warmed to body temperature after insertion inside the body (if this is required). In addition, it should preferably coat the implant or device smoothly and evenly, with a uniform distribution of anti-connexin agent, while not changing the stent contour. Within preferred embodiments of the invention, the anti- connexin agent or composition should provide a uniform, predictable, prolonged release of the anti-connexin factor into the tissue surrounding the implant or device once it has been deployed. For vascular stents, in addition to the above properties, the composition should not render the stent thrombogenic (causing blood clots to form), or cause significant turbulence in blood flow (more than the stent itself would be expected to cause if it was uncoated). [00117] Delivery of anti-connexin agents utilizing a stent can be carried out in a number of ways, including, for example, from the struts of a stent, a stent graft, the catheter used to deliver the stent, the stent cover or sheath. Various methods of applying a therapeutic agent to a stent and administering the therapeutic agent via the stent are disclosed in U.S. Patent Nos. 6,702,850; 6,585,764; 6,358,556; 6,344,028; 6,251,136; 5,697,967; 5,599,352; 5,591,227; 5,464,650; 5,304,121; 5,163,952; 5,092,877; 4,994,071; and 4,916,193, the disclosures of which are incorporated in their entirety herein by reference. Other devices may be coated or impregnated using these or other techniques in the art, including those now known or later developed. [00118] Any one or more of the foregoing medical devices can include an overlayer of any type, including, for example, a fabric such as a sheath, an encasement, a layer, or a coating, such that the fabric overlayer is in contact with body tissue or fluids such as blood. Alternatively, instead of a fabric overlayer, the medical device may include any other type of layer such as, for example, a mesh, coil, wire, inflatable balloon, bead, sheet, or any other structure which is capable of being used or implanted at a target location, including, for example, intravascular 40 target locations, intra-joint locations, intraluminal target locations, intra-orbital and intra-ocular target locations, target locations within solid tissue, joints, heart, intestine, eyes, etc. Impregnated Dressings and Matrices [00119] In one aspect, medical devices are provided in the form of a dressing or matrix comprising one or more anti-connexin agents, one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents.

[00146] In one embodiment, the release rate of the anti-connexin agent is controlled. In one embodiment of the invention, the anti-connexin agent may be released slowly or over a sustained period. In one embodiment the anti-connexin agent is released, for example, over the period of the resorption or degradation of the body of the medical device, or a portion thereof. [00147] In one embodiment of the invention, the surface of the medical device comprises an anti-connexin agent, e.g., an anti-connexin 43 agent. In one aspect of the invention an anti connexin agent is bound, either directly or indirectly, to a medical device. In another aspect of the invention, an anti-connexin agent is bound, directly or indirectly, to a surface of a medical device. In another aspect of the invention, this surface contacts a tissue within a subject. In one embodiment, the target tissue is heart tissue, vascular tissue, muscle tissue, or connective tissue. In yet another embodiment, this surface contacts a site of injury or potential injury. In another 45 embodiment, the medical device provides for surface contact release of the anti-connexin agent, e.g., an anti-connexin 43 agent. [00148] In one embodiment, an anti-connexin agent, e.g., an anti-connexin 43 agent, is present in a coating on a surface of the medical device. Such coatings include, for example, synthetic or natural matrices, for example, fibrin or acetate-based polymers, mixtures of polymers or copolymers, which can also be bioresorbable or biodegradable matrices, and which matrices have or include or incorporate an anti-connexin agent. Such matrices can, for example, provide for surface contact or metered or sustained release of one or more anti-connexin agent. [00149] In another embodiment, the device comprising an anti-connexin agent, e.g., an anti connexin 43 agent, may be formed, at least in part, for example, from a biodegradable or bioresorbable polymer material.

Examples of such materials include, but are not limited to, for example, synthetic polymers or copolymers containing one or more anti-connexin agents, surfaces upon which a functionalized monolayer containing the anti-connexin agent is adsorbed or otherwise attached, or synthetic polymeric materials or proteins blended with one or more anti-connexin agents. [00151] In another aspect, all or a portion of the medical device is coated with an anti connexin agent, e.g., an anti-connexin 43 agent, either as the coating per se or in a coating matrix, for example; or all or a portion of the medical device may be produced from a material which includes an anti-connexin agent, for example, a polymer which has admixed therewith an anti-connexin agent or which includes a functionalized anti-connexin agent; or all or a portion of the tissue-contacting surfaces of the medical device may be derivatized with an anti-connexin agent. [00152] The medical device can be coated using any one or more methods known in the art, for example, dip coating, spray coating, sponging or brushing. The coating may contain the anti connexin agent, e.g., an anti-connexin 43 agent, in a weight percentage range of from about 0.0001% to about 30%, for example, although other amounts are contemplated and may be used. 46 Thus, according to one option, the coating may contain anti-connexin agent in a weight percentage range of about 0.001% to about 25%, alternatively in a range of about 0.01% to about 20%, about 0.1% to about 15%, about 0.5% to about 12%, about 1% to about 10%, about 2% to about 10%, about 5% to about 10%, about 0.01% to about 5%, about 0.1% to about 5% or about 0.5% to about 5%. The weight percentage for the anti-connexin agent will be adjusted as appropriate, in view of considerations which include, but are not limited to, the following: the dose of anti-connexin agent to be delivered locally, the rate of release of anti-connexin agent from the coating and the time period for delivery of anti-connexin agent. Included within the coating may be further suitable excipients, for example, a polymer and/or those excipients that aid in the binding of the coating to the anti-connexin agent (or visa versa) and/or that aid in the release of the anti-connexin agent. Alternatively, excipients can be bound to the anti-connexin agent, for example, a polymer or other substance that entraps the anti-connexin agent on or within the surface of the medical device. [00153] The medical device can also be coated using any one or more methods known in the art, to deliver amounts of an anti-connexin agent ranging from about 0.1 micrograms to about 1 milligram or more, in amounts ranging from about 1 micrograms to about 750 micrograms, in amounts ranging from about 5 micrograms to about 600 micrograms, in amounts ranging from about 10 micrograms to about 500 micrograms, in amounts ranging from about 20 micrograms to about 400 micrograms, in amounts ranging from about 30 micrograms to about 300 micrograms, in amounts ranging from about 50 micrograms to about 200 micrograms, and in amounts ranging from about 50 micrograms to about 100 micrograms, for example, although other amounts are contemplated and may be used, including ranges that include only the lower amounts (or the upper amounts) from the above ranges, for example, amounts ranging from about 1-10 micrograms, about 1-5 micrograms, about 10-50 micrograms, and so on (and amounts ranging from about 100-200 micrograms, about 500-600 micrograms, about 300-400 micrograms, and so on). The amounts of the anti-connexin agent will be adjusted as appropriate, in view of considerations that include, but are not limited to, the following: the dose of anti-connexin agent to be delivered locally, the rate of release of anti-connexin agent from the coating and the time period for delivery of anti-connexin agent, the size and nature of the injury, the extent of anticipated tissue damage, inflammation, and so on. [00154] In certain embodiments, methods or coating and dosing/dosage information for the exemplary compounds useful in accordance with the present disclosure may be found in U.S. Pat. 47 No. 7,153,822 to Jensen et al., U.S. Pat. No. 7,250,397, Green et al., W02006134494; Gourdie et al., see W02006069181, and Tudor et al., see W02003032964. [00155] In another aspect, all or a portion or portions of the medical device may be coated with the anti-connexin agent per se or with a pharmaceutically acceptable carrier or excipient comprising the anti-connexin agent which serves as a coat or coating matrix. This may be a solid, liquid, gel or semisolid consistency, for example. [00156] The carrier or matrix can be made of or include agents which provide, for example, for metered or slow or sustained release of the anti-connexin agent and/or other therapeutic agent(s). The coating, for example, can include albumin that can be either, for example, human or bovine, including humanized bovine serum albumin. [00157] A coating may be applied as a single coating or in multiple coatings or layers. The multiple coatings or layers can include varying ratios of anti-connexin agent-to-carrier to vary the release rate of the drug over time. The multiple coatings or layers can also include different medicaments in accordance with a desired treatment plan. In one embodiment, the coating comprises a plurality of coatings or layers of a polymer/anti-connexin agent mixture, e.g., an anti-connexin 43 agent mixture, applied to the medical device. In another embodiment, the anti connexin agent-to-polymer ratio in the plurality of coatings or layers varies. [00158] In another aspect, anti-connexin agents, e.g., an anti-connexin 43 agents, may be impregnated or otherwise incorporated into the body of all or a portion of the medical device. [00159] Additionally, the anti-connexin agent, e.g., an anti-connexin 43 agent, may be provided in one or more reservoirs or channels formed in the medical device, optionally with a coating or membrane of biocompatible material applied over the medical device to control diffusion of the drug from the reservoirs/channels to the tissue. In one embodiment, the medical device comprises at least one channel formed in an outer surface thereof, and wherein the anti connexin agent is included on and/or within at least one channel. [00160] In another aspect, if a "burst effect" is desired, the anti-connexin agent, e.g., an anti connexin 43 agent, may be applied at the outer layer of the medical device (and/or within the device, as well) so that an initial amount of the anti-connexin agent is promptly released when it comes into contact with tissue. Remaining amounts, if any, of anti-connexin agent included in the inner layers will be released over time as the anti-connexin agent diffuses through the material. The anti-connexin agent may be provided either in liquid or solid form. [00161] In another aspect, the coating applied to the medical device can be "recharged", for example, by way of a catheter or other tubing capable of infusing an anti-connexin agent donor to 48 a previously coated surface or impregnated or other device comprising an anti-connexin agent. For example, in one embodiment, the anti-connexin agent may be functionalized to form an anti connexin agent-protein that will lose potency in vivo as the functionalized-anti-connexin agent protein is metabolized, leaving un-derivatized protein. The surface coating can be "recharged" by infusing an anti-connexin agent or anti-connexin agent donor capable of binding the un derivatized protein. [00162] In another aspect of the invention, the derivatization.of an artificial surface with an anti-connexin agent provides for the amelioration of tissue damage, and/or enhancement of tissue repair, as well as the prevention and/or amelioration of inflammation. The artificial surfaces may be composed of organic materials or a composite of organic and inorganic materials. Examples of such materials include synthetic polymers or copolymers containing one or more anti-connexin agents, surfaces upon which a functionalized monolayer containing the anti connexin agent is absorbed, or synthetic polymeric materials or proteins which are blended with the anti-connexin agent. [00163] In one embodiment of the invention, the localized and/or time-related presence of an anti-connexin agent, e.g., an anti-connexin 43 agent, administered in a physiologically effective form is efficacious in diminishing, deterring or preventing tissue damage, including inflammation, after or as a result of instrumental intervention, such as angioplasty, catheterization, or the introduction of a stent (e.g., a Palmaz-Schatz stent), shunt, mesh, joint replacement, or other surgical or indwelling medical device. Local administration of a stable anti-connexin agent inhibits neutrophil and/or macrophage migration following vascular arterial balloon injury, for example, as well as inflammation, swelling and hypeplasia. This strategy for the local delivery of an anti-connexin agent is useful, among other things, for the treatment of vascular injury following angioplasty, and other treatments that can result in vessel or tissue disturbance. [00164] In a further embodiment, the invention provides for the localized use of a functionalized anti-connexin agent-polypeptide or polynucleotide, particularly those which do not elicit any significant or otherwise undesired immune response. Such functionalized anti connexin agent-polypeptides or polynucleotides, such as, for example, functionalized anti connexin agent-albumins, can be present as polymeric chains or three dimensional aggregates where the functionalized anti-connexin agent-polypeptide or polynucleotide is the monomeric unit. The polypeptide or polynucleotide of the monomeric unit can also be used to aid, for example, in localization. The aggregates may be multiple inter-adherent monomeric units which 49 can optionally be linked by disulfide bridges or -0- linkages, for example. Additionally, devices which have been substituted or coated with one or more functionalized anti-connexin agent polypeptides or polynucleotides may be dried and stored. [00165] In another aspect, the invention relates to a method of preventing and/or treating damage, including inflammation, associated with the use or implantation of a medical device in a subject comprising introducing into said subject a medical device of which at least a portion comprises an anti-connexin agent, wherein said damage and/or inflammation is prevented, reduce, ameliorated and/or delayed. [00166] In another aspect, the invention related to a method of preventing and/or treating damage and/or inflammation associated with the use or implantation of a medical device in a subject comprising use or implantation of a medical device which comprises an anti-connexin agent that is releasable at its point of contact, wherein the damage and/or inflammation is prevented, amerliorated and/or delayed. [00167] In yet another aspect, the invention relates to a method of preventing and/or treating adverse effects associated with the use or insertion of a medical device in a subject, wherein an anti-connexin agent is locally administered at the site of contact of said medical device, before, during and/or after said use or insertion, wherein said adverse effects are prevented, ameliorated, reduced or delayed. Such adverse effects include inflammation, swelling, hyperplasia, neutrophil migration, and macrophage migration, as well as blood vessel disturbance and/or leakage. [00168] In another aspect, the invention relates to a method of treating a damaged vessel in a subject in need thereof which comprises introducing into said vessel at the site of damage a catheter, a balloon, a graft, a mesh, a stent or a shunt comprising an anti-connexin agent, e.g., an anti-connexin 43 agent. [00169] In another aspect, the invention comprises a method of ameliorating tissue damage and/or enhancing tissue repair by locally administering one or more anti-connexin agents, e.g., an anti-connexin 43 agent, to the site of tissue in need thereof. Such tissue may be damaged, or have been damaged, for example, as a result of the use of a medical device in an invasive procedure. Thus, for example, in treating blocked vasculature, by, for example, angioplasty, damage to the blood vessel can result. Additionally, tissue damage can result when medical devices are left within a subject for an extended period of time. Such damage may be treated by use of an anti-connexin agent. In addition to ameliorating tissue damage and/or enhancing repair of the damaged tissue, such treatment can also be used to prevent and/or alleviate and/or delay occlusions, including for example, acute occlusion and reocclusions. Treatment may also be 50 used to prevent and/or ameliorate and/or delay thrombosis and restenosis. Treatment may also be used to prevent and/or ameliorate and/or delay inflammation. Treatment may also be used to prevent and/or ameliorate and/or delay hyperplasia. Treatment may also be used to prevent and/or ameliorate and/or delay oxidative damage, including, for example oxidative damage by free radicals, including superoxide damage. In other aspect, the invention, treatment may also be used to treat and/or prcvcnt and/or alleviate and/or delay atherosclerotic lesions, and undesired cell proliferation and migration. [00170] In one embodiment the invention comprises a method of ameliorating tissue damage and/or enhancing tissue repair wherein the subject is a mammal. In another embodiment the invention comprises a method of ameliorating tissue damage and/or enhancing tissue repair wherein the subject is human. In another embodiment the invention comprises a method of ameliorating tissue damage and/or enhancing tissue repair wherein the subject is selected from the group consisting of domestic and pet animals (for example, horses, dogs and cats), sports animals (for example, horses and dogs), farm animals, and zoo animals, as well as birds. [00171] In one embodiment the medical device comprising an anti-connexin agent can include one or more other therapeutic agents and /or wound healing agents. In one embodiment, the therapeutic agents may be applied or included directly with the anti-connexin agent, e.g., an anti-connexin 43 agent. In another embodiment, the therapeutic agent may be applied or included in the same coating or coating layer with the anti-connexin agent. In yet another embodiment, the therapeutic agent may be applied or included in separate coating or coating layer or a separate portion of the device. [00172] In one embodiment, the anti-connexin agent is an anti-connexin 43 compound. In another embodiment, the anti-connexin agent downregulates or inhibits connexin 43 mRNA. In another embodiment, the anti-connexin agent suppresses the formation of connexin 43 gap junctions. In another embodiment, the anti-connexin agent suppresses the joining of connexin 43 hemichannels to form gap junctions. In another embodiment, the anti-connexin agent suppresses connexin 43 hemichannel opening. [00173] In another embodiment, the the anti-connexin agent targets connexin 31, connexin 31.1, or connexin 43. Preferably, the anti-connexin agent targets connexin 43. [00174] There are various techniques known in the art for the localized delivery of therapeutic agents, for example, but not limited to, by means of a small catheter which extends from the exterior of the subject to the internal tissue site, with a mechanical delivery system being provided to administer a therapeutic agent in a continuous or periodic controlled dosage. 51 This method can be utilized for subjects in need of therapeutic treatment by repeat application. Anti-connexin agents, e.g., an anti-connexin 43 agents, can also be delivered arthoscopically using devices known in the art, which may themselves be coated or impregnated, for example, with an anti-connexin agent, e.g., an anti-connexin 43 agent. [00175] Any catheter, however, is within the scope of the invention, including those for the delivery of therapeutic agents or otherwise. These include, for example, urological catheters (including intermittent catheters, external catheters, and Foley catheters), pancreatic catheters, hepatic catheters, infusion catheters, cardiovascular catheters, renal catheters, hemodynamic monitoring catheters, neurological catheters, and so on. Cannulae, as noted above, are also included. [00176] The method of applying one or more anti-connexin agents, e.g., an anti-connexin 43 agent, to an internal tissue site of a subject comprises, for example, advancing an elongate member, such as a catheter (which may itself be coated or impregnated with one or more anti connexin agents), internally into the subject to cause a portion of the elongated member to occupy the internal tissue site. A portion of the elongated member comprises a lateral wall section which carries the anti-connexin agent in a manner permitting release thereof from the lateral wall section at the internal tissue site once the site has been reached. This can be determined by the usual methods, such as for example, fiber optic television, x-ray, etc. [00177] The release of the anti-connexin agent at the internal tissue site can occur for example by the use of a catheter balloon, which when inflated causes the anti-connexin agent to be pressed into and/or onto the tissue at the internal tissue site. This allows at least some of the anti-connexin agent to be retained at the tissue site once the catheter balloon is deflated. [00178] The anti-connexin agent can also be mixed with a controlled release carrier and administered in the manner discussed above, for example. Such controlled release carriers can be biodegradable over a period of time, for example, over a period of hours or days, so that as the controlled release carriers are brought into contact with the tissues and/or fluids the controlled release carriers degrade over time to allow for a relatively slow, controlled diffusion of the anti connexin agent to the tissue and/or fluids. The carrier over time will be removed by natural bodily processes. [00179] The catheter or balloon catheter or other device used to apply a stent to the coronary artery or elsewhere may also be provided with a coating of heparin or other anti-thrombogenic agent, for example, in conjunction with one or more anti-connexin agents, e.g., an anti-connexin 43 agent, that may be combined with a carrier or a controlled release carrier for the anti-connexin 52 agent. Thus, simultaneously with the application of the anti-connexin agent, the heparin or other anti-thrombogenic agent, for example, is applied to the internal tissue site for the long term suppression of thrombogenic activity in the vicinity of the stent in addition to therapeutic effects from the anti-connexin agent. [00180] In addition, while the catheter or other elongate member, for example, is being used to position the stent and is being advanced to the internal tissue site, the portion of the catheter carrying the anti-connexin agent may be enclosed in a protective sheath. The sheath is used to prevent removal of substantial amounts of the anti-connexin agent from the catheter before reaching the desired internal site. When the site is reached, the protective sheath may be withdrawn to expose the catheter portion carrying the anti-connexin agent. The anti-connexin agent, e.g., an anti-connexin 43 agent, can then be applied to the internal site, for example, by expansion of a catheter balloon upon which the anti-connexin agent resides, or by other processes such as spontaneous dispersion off the catheter into the tissues. If desired, the protective sheath may be a conventional introducer catheter, or it may be a split introducer sheath to facilitate removal of the sheath from the catheter after its withdrawal, for example. [00181] One example of a method of coating a medical device having more than one surface or requiring only a portion of a surface of the medical device to be treated is to treat the device with gas plasma that may, for example, be composed of a molecular species containing the anti connexin agent. In the case of stents, it is particularly desirable to treat the entire surface. In the case of balloons mounted on catheters, it is desirable to coat at least the outer cylindrical surface of the balloon that will be in contact with a blood vessel or other tissue when the balloon is inflated. [00182] Alternatively, the anti-connexin agent can be mixed with polymers (both degradable and non degradable), for example, to hold a anti-connexin agent(s) to a stent or graft or other device, or the anti-connexin agent can be entrapped into the material of, for example, a stent or graft body, or other device. [00183] Alternatively the anti-connexin agent can be covalently bound to, for example, a stent or other device via solution chemistry techniques or dry chemistry techniques (for example, vapour deposition methods such as rf-plasma polymerization) and combinations thereof. [00184] Another method of coating a surface of a medical device with one or more anti connexin agents, e.g., an anti-connexin 43 agent, comprises contacting the surface with an anti connexin agent(s) so as to cause the surface to be coated with the particular anti-connexin agent. 53 Coating of the artificial surface may be accomplished using the methods described in the Examples, or other methods known in the art. [00185] For example, coating a surface with an anti-connexin agent, e.g., an anti-connexin 43 agent, can be achieved by bathing the artificial surface, either by itself or within a device, in a solution containing the anti-connexin agent. In addition, synthetic anti-connexin agents may be coated onto an artificial surface by a variety of chemical techniques which are well known in the art. Such techniques include attaching the anti-connexin agent, for example, a functionalized compound, by means of a linking group, or to a nucleophilic center, epoxide, lactone, an alpha or beta-saturated carbon chain, alkyl halide, carbonyl group, or Schiff base, by way of a reactive group, for example, a free thiol. [00186] A medical device may be coated using a variety of different techniques. The coating may be applied as a mixture, solution or suspension of polymeric material, for example, and one or more finely divided anti-connexin agents dispersed in an organic vehicle or a solution or partial solution of such anti-connexin agent(s) or binding compound(s) in a solvent or vehicle for the polymer and/or anti-connexin agent(s) or binding compound(s). For the purposes of this patent, the term "finely divided" means any type or size of included material from dissolved molecules through suspensions, colloids and particulate mixtures, or that otherwise serve the intended purpose. One or more anti-connexin agents can be disbursed in the carrier material, which may be the polymer, a solvent, or both, for example. The coating may be applied as a single layer or as a plurality of layers, typically relatively thin layers, sequentially applied, for example, in relatively rapid sequence. In some applications, the coating may further be characterized as a composite initial tie coat, or undercoat, and a composite topcoat. The coating thickness ratio of the topcoat to the undercoat may vary with the desired effect and/or the elution system. Typically, the topcoat and undercoat are of different formulations, but need not be. Providing an anti-connexin agent(s) and/or binding compound(s) as a plurality of layers on the medical device enables both an initial burst effect of drug elution and the drug release kinetic profile associated with long term therapeutic effect to be controlled. [00187] Various combinations of coating materials, such as polymer coating materials, for example, can be coordinated with biologically or chemically active species of interest to produce desired effects when coated on stents or other medical devices to be implanted, or inserted, in accordance with the invention. Loadings of therapeutic materials may vary, as well as the types of therapeutic material. The mechanism of incorporation of the biologically or chemically active species into the surface coating, as well as the egress mechanism, depends both on the nature of 54 the surface coating polymer and the therapeutic material to be incorporated. The mechanism of release also depends on the mode of incorporation. The therapeutic material may elute via interparticle paths or be administered via transport or diffusion through the encapsulating material itself. [00188] Suitable polymers for use in the coating include, for example, a polymer that is biocompatible and minimizes irritation to the vessel wall when a medical device is implanted. It is advantagous that such polymer exhibit high elasticity/ductility, resistance to erosion, elasticity, and controlled drug release. Such polymer may be either a biostable or a bioabsorbable polymer depending on the desired rate of release or the desired degree of polymer stability. Bioabsorbable polymers that may be used include poly(L-lactic acid), polycaprolactone, poly(lactide-co-glycolide), poly(ethylene-vinyl acetate), poly(hydroxybutyrate-co-valerate), polydioxanone, polyorthoester, polyanhydride, poly(glycolic acid), poly(D,L-lactic acid), poly(glycolic acid!co-trimethylene carbonate), polyphosphoester, polyphosphoester urethane, poly(amino acids), cyanoacrylates, poly(trimethylene carbonate), poly(iminocarbonate), copoly(ether-esters) (e.g. PEO/PLA), polyalkylene oxalates, polyphosphazenes and biomolecules such as fibrin, fibrinogen, cellulose, starch, collagen and hyaluronic acid. [00189] Also, biostable polymers with a relatively low chronic tissue response such as polyurethanes, silicones, and polyesters could be used and other polymers may also be used if they can be dissolved and cured or polymerized on the medical device such as polyolefins, polyisobutylene and ethylene-alphaolefin copolymers; acrylic polymers and copolymers, ethylene-co-vinylacetate, polybutylmethacrylate, vinyl halide polymers and copolymers, such as polyvinyl chloride; polyvinyl ethers, such as polyvinyl methyl ether; polyvinylidene halides, such as polyvinylidene fluoride and polyvinylidene chloride; polyacrylonitrile, polyvinyl ketones; polyvinyl aromatics, such as polystyrene, polyvinyl esters, such as polyvinyl acetate; copolymers of vinyl monomers with each other and olefins, such as ethylene-methyl methacrylate copolymers, acrylonitrile-styrene copolymers, ABS resins, and ethylene-vinyl acetate copolymers; polyamides, such as Nylon 66 and polycaprolactam; alkyd resins; polycarbonates; polyoxymethylenes; polyimides; polyethers; epoxy resins, polyurethanes; rayon; rayon-triacetate; cellulose, cellulose acetate, cellulose butyrate; cellulose acetate butyrate; cellophane; cellulose nitrate; cellulose propionate; cellulose ethers; and carboxymethyl cellulose. [00190] Accordingly, the coating comprising an anti-connexin agent, e.g., an anti-connexin 43 agent, may be formed, at least in part, for example, from a biodegradable or bioresorbable polymer material. Polymer materials can include, for example, but are not limited to, nylon, 55 polyethylene perthalate, polytetrafluoroethylene, etc. Other polymers may also include, for example, hexafluoropropylene (HFP), tetrafluoroethylene (TFE), vinylidenefluoride, 1 hydropentafluoropropylene, perfluoro(methyl vinyl ether), chlorotrifluoroethylene (CTFE), pentafluoropropene, trifluoroethylene, hexafluoroacetone and hexafluoroisobutylene. [00191] The desired release rate profile can be tailored by, for example, varying the coating thickness, the radial distribution (layer to layer) of bioactive materials, the number of layers, the mixing method, and the amount of bioactive material(s), the combination of different materials, for example, matrix polymer materials, at different layers, and the crosslink density of a polymeric material. The crosslink density is related to the amount of crosslinking which takes place and also the relative tightness of the matrix created by the particular crosslinking agent used. Thus, the curing process of such a coating typically determines the amount of crosslinking and also the crosslink density of the polymer material. For bioactive materials released from a crosslinked matrix, a crosslink structure of greater density will increase release time and reduce burst effect. By applying at least one therapeutically active anti-connexin agent at the outer layer of the medical device, a burst effect may be made to occur where a large amount of the anti connexin agent is immediately or promptly released when it comes into contact with the tissue. Subsequently, longer term release of the anti-connexin agent will occur as it diffuses through the material, for example, a polymeric material. [00192] The elution kinetics of an anti-connexin agent, e.g., an anti-connexin 43 agent, can be modified to meet the needs of the particular medical device application. For example, medical devices can be coated using a combination of an anti-connexin agent with one, two or more other medicaments, where the release sequence can be rate controlled. For example, one or more anti connexin agents may be combined in the undercoat layer, and anti-thrombotic drugs, for example, heparin, may be provided in the topcoat layer. In this manner, the anti-thrombotic drugs will elute first, followed by the anti-connexin agent(s). In the case where the medical device is an implanted stent, this combination of drugs may better enable safe encapsulation of the implanted stent. Any desired drug may be included in this manner. [00193] Alternately, the drug coating may include a base coat layer applied directly to the surfaces of the medical device, a second layer which includes a pharmacological agent, for example, an anti-connexin agent, e.g., an anti-connexin 43 agent, and a third layer in the form of a continuous membrane encapsulating the entire device. The base coat serves as a primer by readily adhering to the surface of the medical device and then readily accepting and retaining the anti-connexin agent(s) applied thereto. The base coat may include materials such as vitronectin, 56 fibronectin, gelatin, collagen, and/or other similar materials, for example, which are relatively inexpensive and dry to form a sticky coating. An anti-connexin agent may be supplied in the form of dry, micronized particles, for example, that readily adhere to the sticky base layer surface. It is preferred that the anti-connexin agent may have a particle size of about 0.005 to about 3.0 micro metres, or such size may be different, if desired. Other particle sizes are contemplated depending on the particular medical application and device to which the anti connexin agent(s) is/are being applied. The outer membrane or layer may encapsulate the entire medical device to cover all of its surfaces, including any bare device structure, any exposed base coating or the layer of micronized anti-connexin agent(s) or other medicament particles. [00194] The material selected to form the membrane is dependent on its membrane forming characteristics and its biocompatibility, as well as its permeability to an anti-connexin agent, e.g., an anti-connexin 43 agent. The chemical composition of the membrane forming polymer, for example, and that of an anti-connexin agent, in combination with the thickness of the applied outer layer, will determine the diffusion rate of the anti-connexin agent. [00195] The overall -coating should be thin enough so that it will not significantly increase the profile of the medical device when inserted into a mammal. In the case of implantable stents, the coating is, for example, from between 0.005 microns to about 400 microns thick. However, other thicknesses may be utilized without departing from the spirit and scope of the present invention. The adhesion of the coating and the rate at which the drug is delivered can be controlled by the selection of an appropriate bioabsorbable or biostable material, such as a polymer, and by the ratio of the drug-to-polymer in the solution. In the case where multiple layers are utilized to coat the medical device, the release rate can be further controlled by varying the ratio of, for example, anti-connexin agent-to-polymer, in the multiple layers. For example, a higher anti-connexin agent-to-polymer ratio in the outer layers than in the inner layers would result in a higher early dose which would decrease over time. [00196] In an alternate form, the medical device can include reservoirs, or channels, which may be loaded with one or more anti-connexin agents, e.g., an anti-connexin 43 agent. Such reservoirs can aid in decreasing the profile of the coated device, since the anti-connexin agent or a portion of the anti-connexin agent would be provided within the reservoir or channel. In such an embodiment, the anti-connexin agent is provided in the reservoirs, and a coating or membrane of biocompatible material is applied over the reservoir which controls the diffusion of the anti connexin agent from the reservoirs to the tissue. Further layers of anti-connexin agent and/or 57 materials, for example, polymeric materials, may be applied to the device in accordance with the teachings herein without departing from the spirit and scope of the present invention. [00197] The amount of anti-connexin agent included in the layer(s) will vary depending on the dosage required for effective therapeutic treatment. A therapeutically effective amount of a anti-connexin agent may be determined from the doses of such compounds administered topically that typically will vary from about 0.1 micrograms to about I milligram or more per square millimeter or per square centimeter of device surface, in amounts ranging from about 1 micrograms to about 750 micrograms, in amounts ranging from about 5 micrograms to about 600 micrograms, in amounts ranging from about 10 micrograms to about 500 micrograms, in amounts ranging from about 20 micrograms to about 400 micrograms, in amounts ranging from about 30 micrograms to about 300 micrograms, in amounts ranging from about 50 micrograms to about 200 micrograms, and in amounts ranging from about 50 micrograms to about 100 micrograms, for example, although other amounts are contemplated and may be used, including ranges that include only the lower amounts (or the upper amounts) from the above ranges, for example, amounts ranging from about 1-10 micrograms, about 1-5 micrograms, about 10-50 micrograms, and so on (and amounts ranging from about 100-200 micrograms, about 500-600 micrograms, about 300-400 micrograms, and so on). The amounts of the anti-connexin agent will be adjusted as appropriate, in view of considerations that include, but are not limited to, the following: the dose of anti-connexin agent to be delivered locally, the rate of release of anti connexin agent from the coating and the time period for delivery of anti-connexin agent, the size and nature of the injury, the extent of anticipated tissue damage, inflammation, and so on. [00198] The amount of anti-connexin agent in the coating or layer is adjusted so that the desired dose of anti-connexin agent, e.g., an anti-connexin 43 agent, is delivered at the desired delivery rate for the desired time of delivery. The time of delivery will depend on factors which include the time period for which the device is intended to be implanted in the subject. [00199] In one embodiment the coating may contain anti-connexin agent in a weight percentage of from about 0.0001% to about 30%. As noted above, depending on dose, rate of delivery, period of delivery and other factors, other amounts are contemplated and may be used. Thus, according to one option, the coating may contain anti-connexin agent in a weight percentage range of about 0.001% to about 25%, alternatively in a range of about 0.01% to about 20%, about 0.1% to about 15%, about 0.5% to about 12%, about 1% to about 10%, about 2% to about 10%, about 5% to about 10%, about 0.01% to about 5%, about 0.1% to about 5% or about 0.5% to about 5%. The weight percentage for the anti-connexin agent will be adjusted as 58 appropriate, in view of considerations which include, but are not limited to, the following: the dose of anti-connexin agent to be delivered locally, the rate of release of anti-connexin agent from the coating and the time period for delivery of anti-connexin agent. [00200] Other therapeutically effective dosage ranges may be useful. One skilled in the art can customize the desired rate and/or dosage of anti-connexin agent delivery by evaluation and/or selection of an appropriate bioabsorbable or biostable polymer and by the ratio of anti-connexin agent-to-polymer in the coating, for example. [00201] The particular surface or surfaces on which the anti-connexin agent is deposited determines where the anti-connexin agent will be delivered upon implantation. For example, in the case of a stent, anti-connexin agent deposited on the outer exterior surfaces of the stent will cause the anti-connexin agent to pass directly into the lumen wall, while deposition of the anti connexin agent on the outer interior surfaces of the stent will cause the anti-connexin agent to be released directly into the blood stream. Alternately, coating only the upstream edge or only the downstream edge of the stent may be desirable to achieve a desired effect. By selectively coating the stent, or other medical device, surfaces with the anti-connexin agent or other medicaments, the distribution of the anti-connexin agent may be precisely controlled. [00202] It is also contemplated that artificial surfaces will vary depending on the nature of the surface, and such characteristics as contour, crystallinity, hydrophobicity, hydrophilicity, capacity for hydrogen bonding, and flexibility of the molecular backbone and polymers. Therefore, using routine methods, one of ordinary skill will be able to customize the coating technique by adjusting such parameters as the amount of anti-connexin agent, length of treatment, temperature, diluents, and storage conditions, in order to provide optimal coating of each particular type of surface. [00203] After the device or artificial material has been coated or impregnated with one or more anti-connexin agents, it will be suitable for its intended use, for example, implantation as a heart valve, insertion as a catheter, or insertion as a stent, and so on. The coated device or artificial surface will be suitable for use in conjunction with an animal, generally mammals, including humans. [00204] Another embodiment of an anti-connexin agent pertains to the derivatization of synthetically derived polymeric materials by attachment of a functionalized anti-connexin agent such as, for example, a functionalized compound as described herein. Dosage Forms and Formulations 59 [00205] A therapeutically effective amount of each of the combination partners (e.g. an anti connexin agent and a wound healing agent) may be administered simultaneously, separately or sequentially and in any order. The agents may be administered separately or as a fixed combination. When not administered as a fixed combination, preferred methods include the sequential administration of one or more anti-connexin agents and one or more agents useful for wound healing, either or both of which are provided in amounts or doses that are less that those used when the agent or agents are administered alone, i.e., when they are not administered in combination, either physically or in the course of treatment of a wound. Such lesser amounts of agents administered are typically from about one-twentieth to about one-tenth the amount or amounts of the agent when administered alone, and may be about one-eighth the amount, about one-sixth the amount, about one-fifth the amount, about one-fourth the amount, about one-third the amount, and about one-half the amount when administered alone. Preferably, the agents are administered sequentially within at least about one-half hour of each other. The agents may also be administered with about one hour of each other, with about one day to about one week of each other, or as otherwise deemed appropriate. Preferably, the anti-connexin agent is administered first. Preferably, where one or more anti-connexin agents are used, an anti-connexin peptide or anti-connexin peptidomimetic, e.g., an anti-connexin agent that can block or reduce hemichannel opening, is administered prior to the administration of an anti-connexin agent that blocks or reduce connexin expression or the formation of hemichannels or gap junctions, e.g., by downregulation of connexin protein expression. Preferably, the anti-connexin agent or agents is/are anti-connexin 43 agent(s). [00206] The agents of the invention of the may be administered via a medical device to a subject in need of treatment, such as a subject with any of the diseases or conditions mentioned herein. The condition of the subject can thus be improved. The anti-connexin agent and combinational partner may thus be used in the treatment of the subject's body by therapy using the device. They may be used in the manufacture of a medical device as mentioned herein. Thus, in accordance with the invention, there are provided formulations by which cell-cell communication can be downregulated in a transient and site-specific manner. [00207] The anti-connexin agent may be present in a substantially isolated form. It will be understood that the product may be mixed with carriers or diluents which will not interfere with the intended purpose of the product and still be regarded as substantially isolated. A product of the invention may also be in a substantially purified form, in which case it will generally 60 comprise about 90%, e.g. at least about 95%, at least about 98% or at least about 99% of the polynucleotide (or other anti-connexin agent) or dry mass of the preparation. [00208] Depending on the intended route of application, the products of the invention may, for example, take the form of solutions, suspensions, instillations, salves, creams, gels, foams, ointments, emulsions, lotions, paints, sustained release formulations, or powders, and typically contain about 0.1 %-95% of active ingredient(s), preferably about 0.2%-70% as applied to medical devices. Other suitable formulations include pluronic gel-based formulations, carboxymethylcellulose(CMC)-based formulations, and hyroxypropylmethylcellulose(HPMC) based formulations. Other useful formulations include slow or delayed release preparations. [00209] Gels or jellies may be produced using a suitable gelling agent including, but not limited to, gelatin, tragacanth, or a cellulose derivative and may include glycerol as a humectant, emollient, and preservative. Ointments are semi-solid preparations that consist of the active ingredient incorporated into a fatty, waxy, or synthetic base. Examples of suitable creams include, but are not limited to, water-in-oil and oil-in-water emulsions. Water-in-oil creams may be formulated by using a suitable emulsifying agent with properties similar, but not limited, to those of the fatty alcohols such as cetyl alcohol or cetostearyl alcohol and to emulsifying wax. Oil-in-water creams may be formulated using an emulsifying agent such as cetomacrogol emulsifying wax. Suitable properties include the ability to modify the viscosity of the emulsion and both physical and chemical stability over a wide range of pH. The water soluble or miscible cream base may contain a preservative system and may also be buffered to maintain an acceptable physiological pH. [00210] Foam preparations may be formulated to be delivered from a pressurized aerosol canister, via a suitable applicator, using inert propellants. Suitable excipients for the formulation of the foam base include, but are not limited to, propylene glycol, emulsifying wax, cetyl alcohol, and glyceryl stearate. Potential preservatives include methylparaben and propylparaben. [00211] Preferably the agents of the invention are combined with a pharmaceutically acceptable carrier or diluent to produce a pharmaceutical composition for use in or on a medical device. Suitable carriers and diluents include isotonic saline solutions, for example phosphate buffered saline. Suitable diluents and excipients also include, for example, water, saline, dextrose, glycerol, or the like, and combinations thereof. In addition, if desired substances such as wetting or emulsifying agents, stabilizing or ph buffering agents may also be present. [00212] The term "pharmaceutically acceptable carrier" refers to any pharmaceutical carrier that does not itself induce the production of antibodies harmful to the individual receiving the 61 composition, and which can be administered without undue toxicity. Suitable carriers can be large, slowly metabolized macromolecules such as proteins, polysaccharides, polylactic acids, polyglycolic acids, polymeric amino acids, and amino acid copolymers. [00213] Pharmaceutically acceptable salts can also be present, e.g., mineral acid salts such as hydrochlorides, hydrobromides, phosphates, sulfates, and the like; and the salts of organic acids such as acetates, propionates, malonates, benzoates, and the like. [00214] Suitable carrier materials include any carrier or vehicle commonly used as a base for creams, lotions, gels, emulsions, lotions or paints for topical administration. Examples include emulsifying agents, inert carriers including hydrocarbon bases, emulsifying bases, non-toxic solvents or water-soluble bases. Particularly suitable examples include pluronics, HPMC, CMC and other cellulose-based ingredients, lanolin, hard paraffin, liquid paraffin, soft yellow paraffin or soft white paraffin, white beeswax, yellow beeswax, cetostearyl alcohol, cetyl alcohol, dimethicones, emulsifying waxes, isopropyl myristate, microcrystalline wax, oleyl alcohol and stearyl alcohol. [00215] The pharmaceutically acceptable carrier or vehicle may a gel, for example a nonionic polyoxyethylene-polyoxypropylene copolymer gel, for example, a Pluronic gel, preferably Pluronic F-127 (BASF Corp.). This gel is is a liquid at low temperatures but rapidly sets at physiological temperatures, which confines the release of the agent to the site of application or immediately adjacent that site. [00216] An auxiliary agent such as casein, gelatin, albumin, glue, sodium alginate, carboxymethylcellulose, methylcellulose, hydroxyethylcellulose or polyvinyl alcohol may also be included in the formulation of the invention. [00217] Other suitable formulations for coating or imprenating devices include pluronic gel based formulations, carboxymethylcellulose(CMC)-based formulations, and hyroxypropylmethylcellulose(HPMC)-based formulations. The composition may be formulated for any desired form of delivery. Other useful formulations include slow or delayed release preparations. [00218] Where the anti-connexin agent is a nucleic acid, such as a polynucleotide, uptake of nucleic acids by mammalian cells is enhanced by several known transfection techniques for example those including the use of transfection agents. Such techniques may be used with certain anti-connexin agents, including polynucleotides. The formulation which is used may contain such transfection agents. Examples of these agents include cationic agents (for example calcium 62 phosphate and DEAE-dextran) and lipofectants (for example lipofectam TM and transfectam

TM

), and surfactants. [00219] Where the anti-connexin agent comprises a polynucleotide, the formulation may also includes a surfactant to assist with polynucleotide cell penetration or the formulation may contain any suitable loading agent. Any suitable non-toxic surfactant may be included, such as DMSO. Alternatively a transdermal penetration agent such as urea may be included. [00220] The effective dose for a given device can be determined by routine experimentation or other methods known in the art or later developed. For example, in order to formulate a range of dosage values, cell culture assays and animal studies can be used. The dosage of such compounds preferably lies within the dose that is therapeutically effective for at least 50% of the population, and that exhibits little or no toxicity at this level. [00221] The effective dosage of each of the anti-connexin agents employed in the devices of the invention may vary depending on a number of factors including the particular anti-connexin agent or agents employed, the combinational partner, the mode of administration, the frequency of use of the device or whether it is implanted, the condition being treated using the device, etc. [00222] A suitable amount may be from about 0.001 to about 1 mg/kg body weight such as about 0.01 to about 0.4 mg/kg body weight. A suitable dose may however be from about 0.001 to about 0.1 mg/kg body weight such as about 0.01 to about 0.050 mg/kg body weight. Doses from about 1 to 100, 100-200, 200-300, 300-400, and 400-500 micrograms as well as 500-750 and 750-1000 micrograms are appropriate. [00223] For example, in certain embodiments, the anti-connexin agent composition may be delivered using about 0.01 micromolar (pM) or 0.05 pM to about 200 ptM final concentration at the treatment site and/or adjacent to the treatment site. Preferably, the antisense polynucleotide composition is applied at about 0.05 pM to about 100 pM final concentration, more preferably, the anti-connexin agent composition is applied at about 1.0 PM to about 50 pM final concentration, and more preferably, the anti-connexin agent composition is applied at about 5-10 pM to about 30-50 pM final concentration. Additionally, the combined anti-connexin agent composition is applied at about 8 pM to about 20 pM final concentration, and alternatively the anti-connexin agent composition is applied at about 10 pM to about 20 pM final concentration, or at about 10 to about 15 pM final concentration. In certain other embodiments, the anti connexin agent is applied at about 10 pM final concentration. In yet another embodiment, the anti-connexin agent composition is applied at about 1-15 p.M final concentration. Anti-connexin agent dose amounts include, for example, about 0.1-1, 1-2, 2-3, 3-4, or 4-5 micrograms (pg), 63 from about 5 to about 10 pg, from about 10 to about 15 pg, from about 15 to about 20 pg, from about 20 to about 30 pg, from about 30 to about 40 pg, from about 40 to about 50 jig, from about 50 to about 75 pg, from about 75 to about 100 pg, from about 100 pg to about 250 pg, and from 250 pg to about 500 pg. Dose amounts from 0.5 to about 1.0 milligrams or more or also provided, as noted above. Dose volumes will depend on the size of the site to be treated, and may range, for example, from about 25-100 jL to about 100-200 PL, from about 200-500 pL to about 500-1000 pL. Milliliter doses are also appropriate for larger treatment sites. [00224] Still other dosage levels between about 1 nanogram (ng)/kg and about 1 mg/kg body weight per day of each of the agents described herein. In certain embodiments, the dosage of each of the subject compounds will generally be in the range of about 1 ng to about 1 microgram per kg body weight, about 1 ng to about 0.1 microgram per kg body weight, about 1 ng to about 10 ng per kg body weight, about 10 ng to about 0.1 microgram per kg body weight, about 0.1 microgram to about 1 microgram per kg body weight, about 20 ng to about 100 ng per kg body weight, about 0.00 1 mg to about 100 mg per kg body weight, about 0.01 mg to about 0.1 mg per kg body weight, or about 0.1 mg to about 1 mg per kg body weight. In certain embodiments, the dosage of each of the subject compounds will generally be in the range of about 0.001 mg to about 0.01 mg per kg body weight, about 0.01 mg to about 0.2 mg per kg body weight, about 0.1 mg to about I mg per kg body weight,. If more than one anti-connexin agent is used, the dosage of each anti-connexin agent need not be in the same range as the other. For example, the dosage of one anti-connexin agent may be between about 0.01 mg to about 1 mg per kg body weight, and the dosage of another anti-connexin agent may be between about 0.1 mg to about 0.5 mg per kg body weight. [00225] Conveniently, the anti-connexin agent is administered in a sufficient amount to downregulate or inhibit expression of a connexin protein, or modulate gap junction formation or connexon opening for at least about 0.5 to 1 hour, at least about 1-2 hours, at least about 2-4 hours, at least about 4-6 hours, at least about 6-8 hours, at least about 8-10 hours, at least about 12 hours, or at least about 24 hours post-administration. [00226] The dosage of each of the anti-connexin agents in the compositions and methods of the subject invention may also be determined by reference to the concentration of the composition relative to the size, length, depth, area or volume of the area to which it will be applied. For example, in certain dosing of the pharmaceutical compositions may be calculated based on mass (e.g. micrograms) of or the concentration in a pharmaceutical composition (e.g. pg/pl) per length, depth, area, or volume of the area of application. 64 [00227] Agents useful for wound healing suitable for the preparation of the pharmaceutical compositions described herein may be prepared and administered using methods as known in the art (see, for example, U.S. Patent Nos. 7,098,190, 6,319,907, 6,331,298, 6,387,364, 6,455,569, 6,566,339, 6,696,433, 6,855,505, 6,900,181, 7,052,684 and EPl 100529 B1. The concentration of each anti-connexin agent and agents useful for wound healing need not be in the same range as the other. Other amounts will be known to those of skill in the art and readily determined. For example, suitable combination dosages and formulations in accordance with various aspects and embodiments as described herein may be administered according to the dosing regimen as described in US6903078 to Lewis entitled "Combination PDGF, KGF, IGF, and IGFBP for wound healing." [00228] The wound healing agent may be used in conjuction with a medical device directed towards any tissue. An effective dose of PDGF has been reported to be 5 ng/mm 2 or higher when applied topically as described in U.S. Pat. No. 4,861,757, and at least I ng/ml local concentration of an isoform of PDGF (for example, PDGF-AA, PDGF-BB, or PDGF-AB), up to about 30 ng/ml local concentration applied to a population of fibroblasts as described in Lepisto et al., Biochem Biophys Res. Comm 209: 393-399 (1995). PDGF can be administered in a carboxymethyleellulose gel formulation at concentrations of about 10 jg/gm to about 500 pig/gm of gel, about 20 ptg/gm to about 200 jg/gm, and about 30 jg/gm to about 100 R g/gm of gel, optimally about 100 pg/gm of gel. Efficacy of PDGF has been achieved within the range of about 3 ptg/ml solution to about 300 pg/ml of solution administered. [00229] About 50 pl of KGF of a concentration of about 5 pg/ml may be effective for wound healing by topical application to epithelial tissue as described in Sotozono et al, Invest. Opthal. Vis. Science 36: 1524-29 (1995). As described in U.S. Pat. No. 4,861,757, an effective amount of IGF when co-administered with PDGF is in the range of at least 2.5 ng/mm 2 to about 5 ng/mm 2 , with a ratio of PDGF to IGF in the range of about 1:10 to about 25:1 weight to weight, with the most effective ratios being PDGF to IGF of about 1:1 to about 2:1 weight to weight. IGFBP administered in combination with IGF has been shown to increase wound healing at dose levels of about 5 jig of IGF with about 1.5 ig of phosphorylated IGFBP in a molar ration of about 11:1 IGF:IGFBP, as described in Jyung etal, Surgery 115:233-239 (1994). [00230] For administration of polypeptide therapeutics, for example, PDGF, KGF, IGF and IGFBP polypeptides, the dosage can be in the range of about 5 jig to about 50 pig/kg of tissue to which the application is directed, also about 50 jg to about 5 mg/kg, also about 100 jig to about 500 jg/kg of tissue, and about 200 to about 250 pg/kg. For polynucleotide therapeutics, for 65 example in a gene therapy administration protocol, depending on the expression strength the polynucleotide in the patient, for tissue targeted administration, vectors containing expressible constructs including PDGF, KGF, IGF, and IGFBP coding sequences can be administered in a range of about 100 ng to about 200 mg of DNA for local administration in a gene therapy protocol, also about 500 ng to about 50 mg, also about I pg to about 2 mg of DNA, about 5 pg of DNA to about 500 pg of DNA, and about 20 pg to about 100 pg during a local administration in a gene therapy protocol, and about 250 pg, per injection or administration. Factors such as method of action and efficacy of transformation and expression are therefore considerations that will effect the dosage required for ultimate efficacy for administration of DNA therapeutics. Where greater expression is desired, over a larger area of tissue, larger amounts of DNA or the same amounts re-administered in a successive protocol of administrations, or several administrations to different adjacent or close tissue portions of for example, a wound site may be required to effect a positive therapeutic outcome. [00231] Therapeutic agents and gap junction modifying agents suitable for the preparation of the medical devices described herein may be formulated using methods as known in the art. [00232] As noted herein, the doses of either an anti-connexin agent or another agent administered in combination can be adjusted down from the doses administered when given alone. [00233] The combined use of several agents may reduce the required dosage for any individual agent because the onset and duration of effect of the different agents may be complementary. In a preferred embodiment, the combined use of one or more anti-connexin agents and one or more therapeutic agents, agents useful for wound healing, and/or gap junction modifying agents has an additive, synergistic or super-additive effect. [00234] In some cases, the combination of one or more anti-connexin agents and one or more therapeutic agents and/or one or more agents useful for wound healing, and/or one or more gap junction modifying agents have an additive effect. In other cases, the combination can have greater-than-additive effect. Such an effect is referred to herein as a "supra-additive" effect, and may be due to synergistic or potentiated interaction. [00235] The term "supra-additive promotion of wound healing" refers to a mean wound healing produced by administration of a combination of an anti-connexin agent and one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents, is statistically significantly higher than the sum of the wound healing produced by the individual administration of either any of the agents alone. Whether produced by combination 66 administration of an anti-connexin agent and one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents is "statistically significantly higher" than the expected additive value of the individual compounds may be determined by a variety of statistical methods as described herein and/or known by one of ordinary skill in the art. The term "synergistic" refers to a type of supra-additive inhibition in which both the anti-connexin agent and one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents individually have the ability to promote wound healing or reduce fibrosis and scarring. The term "potentiated" refers to type of supra-additfve effect in which one of the anti connexin agent or one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents individually has the increased ability to promote wound healing. [00236] In general, potentiation may be assessed by determining whether the combination treatment produces a mean wound healing increase in a treatment group that is statistically significantly supra-additive when compared to the sum of the mean wound healing increases produced by the individual treatments in their treatment groups respectively. The mean wound healing increase may be calculated as the difference between control group and treatment group mean wound healing. The fractional increase in wound healing, "fraction affected" (Fa), may be calculated by dividing the treatment group mean wound healing increase by control group mean wound healing. Testing for statistically significant potentiation requires the calculation of Fa for each treatment group. The expected additive Fa for a combination treatment may be taken to be the sum of mean Fas from groups receiving either element of the combination. The Two-Tailed One-Sample T-Test, for example, may be used to evaluate how likely it is that the result obtained by the experiment is due to chance alone, as measured by thep-value. Ap-value of less than.05 is considered statistically significant, that is, not likely to be due to chance alone. Thus, Fa for the combination treatment group must be statistically significantly higher than the expected additive Fa for the single element treatment groups to deem the combination as resulting in a potentiated supra-additive effect. [00237] Whether a synergistic effect results from a combination treatment may be evaluated by the median-effect/combination-index isobologram method (Chou, T., and Talalay, P. (1984) Ad. Enzyme Reg. 22:27-55). In this method, combination index (CI) values are calculated for different dose-effect levels based on parameters derived from median-effect plots of the anti connexin agent alone, the one or more agents useful for wound healing alone, and the combination of the two at fixed molar ratios. CI values of & lt; 1 indicate synergy, Cl-I indicates an additive effect, and CP1 indicates an antagonistic effect. This analysis may be performed 67 using computer software tools, such as CalcuSyn, Windows Software for Dose Effect Analysis (Biosoft(D, Cambridge UK). [00238] Any method known or later developed in the art for analyzing whether a supra additive effect exists for a combination therapy is contemplated for use in screening for suitable anti-connexin agents for use in combination with one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents. [00239] In another preferred embodiment, the combined use of one or more anti-connexin agents and one or more therapeutic agents, agents useful for wound healing, and/or gap junction modifying agents reduces the effective dose of any such agent compared to the effective dose when said agent administered alone. In certain embodiments, the effective dose of the agent when used in combination with one or more anti-connexin agents is about 1/15 to about 1/2, about 1/10 to about 1/3, about 1/8 to about 1/6, about 1/5, about 1/4, about 1/3 or about 1/2 the dose of the agent when used alone. [00240] In another preferred embodiment, the combined use of one or more anti-connexin agents and one or more therapeutic agents, agents useful for wound healing, and/or gap junction modifying agents reduces the frequency in which said agent is administered compared to the frequency when said agent is administered alone. Thus, these combinations allow the use of lower and/or fewer doses of each agent than previously required to achieve desired therapeutic goals. [00241] In one aspect of the invention the anti-connexin agent is administered in one composition and the therapeutic agent, wound healing agent and/or gap junction modifying agent is administered in a second composition. In one embodiment the first composition comprising one or more anti-connexin agents is administered before the second composition comprising one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents. In one embodiment the first composition comprising one or more anti-connexin agents is administered after the second composition comprising one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents. In one embodiment the first composition comprising one or more anti-connexin agents is administered via the medical device before and after the second composition comprising one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents. In one embodiment the first composition comprising one or more anti-connexin agents is administered via the medical device about the same time as the second composition comprising one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents. 68 [00242] Preferably one or more anti-connexin agents and one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents are delivered by topical application via the medical device, including but not limited to application using solid supports (such as matrices) and medicinal layers or coatings as described herein or otherwise known in the art. In one embodiment, the solid support comprises a biocompatible membrane. In another embodiment, the solid support comprises a matrix. In one embodiment of the invention, the solid support composition may be a slow release solid support composition, in which the one or more anti-connexin agents and one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents is dispersed in a slow release solid matrix such as a matrix of alginate, collagen, or a synthetic bioabsorbable polymer. Preferably, the solid support composition is sterile or low bio-burden. [00243] The delivery of one or more anti-connexin agents and one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents of the formulation over a period of time via the medical device, in some instances for about 1-2 hours, about 2-4 hours, about 4-6 hours, about 6-8, or about 24 hours or longer, may be a particular advantage in implanted devices. In some instances, cell loss may extend well beyond the site of a procedure to surrounding cells. Such loss may occur within 24 hours of the original procedure and is mediated by gap junction cell-cell communication. Administration of anti-connexin agent(s), e.g., for downregulation or inhibition of connexin expression, or blockade of connexon opening, therefore will modulate communication between the cells, or loss into the extracellular space in the case of connexon regulation, and minimize additional cell loss or injury or consequences of injury. [00244] While the delivery period will be dependent upon both the site at which the downregulation is to be induced and the therapeutic effect which is desired, continuous or slow release delivery via the medical device for about 1-2 hours, about 2-4 hours, about 4-6 hours, about 6-8, or about 24 hours or longer is provided. In accordance with the present invention, this is achieved by inclusion of the anti-connexin agents and/or one or more therapeutic agents, agents useful for wound healing and/or gap junction modifying agents in a medical device together with a pharmaceutically acceptable carrier, coating, layer or other vehicle, particularly in a form for continuous or slow-release administration. [00245] Various aspects of the invention will now be described with reference to the following experimental section which will be understood to be provided by way of illustration only and not to constitute a limitation on the scope of the invention. 69 EXAMPLES EXAMPLE 1 Determination of Effects from Use of an Anti-connexin Agent-Treated Device in an Animal Model [00246] The following experiment is directed to coating artificial surfaces with an anti connexin agent for amelioration of tissue damage and/or enhanced tissue repair and their testing in an animal model. [00247] Materials: Sodium bicarbonate, sodium chloride, sodium phosphate, sodium nitrite, potassium phosphate-monobasic, 40% formaldehyde solution and sucrose are available from Fischer Scientific, Fairlawn, N.J. Sephadex G25 is available from Pharmacia, Piscataway, N.J. Monoclonal mouse anti-proliferating cell nuclear antigen is available from Dako A/S, Denmark. All other chemicals are available from Sigma Chemical Co., St. Louis, Mo. [00248] Tris-buffered saline consisted of 10 mM tris[hydroxymethyl]aminoethane, pH 7.4, and 150 mM NaCl. Phosphate-buffered saline contained 10 mM sodium phosphate and 150 mM NaCl, pH 7.4. [00249] Anti-Connexin Agent Species: Anti-connexin agent-BSA is synthesized as follows: Fatty acid-free bovine serum albumin (200 mg/ml) is exposed to a 1.4 molar-fold excess of anti connexin agent in PBS for 30 minutes at room temperature. [00250] Thiolated bovine serum albumin (pS-BSA) is prepared after Benesch and Benesch (Benesch R & Benesch RE, "Preparation and properties of hemoglobin modified with derivatives of pyridoxal". Methods Enzymol., 76:147-159 (1981)). Briefly, essential fatty acid-free bovine serum albumin (50 mg/ml) is dissolved in water with N-acetyl-homocysteine thiolactone (35 mM) and 0.05% polyethylenesorbitan monolaurate. Equimolar Silver nitrate is slowly added at room temperature over 90 minutes at pH 8.5. Excess thiourea (70 mM) is added and the pH lowered to 2.5. Excess silver nitrate is removed by Dowex 50 chromatography with the mobile phase consisting of IM thiourea, pH 2.5, and excess thiourea is removed by Sephadex G-25 chromatography. The pS-BSA is prepared within two days of subsequent derivitization and stored at 4'C. Derivitization of pS-BSA is accomplished with 1.4 fold molar excess S triethylenetetramine in 0.5 N HCl for 30 minutes at room temperature. The solution is adjusted to pH 4.0 with 0.5 N NACH after derivitization. Protein content is determined using the method of Lowry and colleagues (Marcus Salier, FASEB.J., 7:516-522, 1993). [00251] Animal Preparation: All animal preparations are performed within institutional guidelines of the host institution. New Zealand white rabbits (3.5-4.2 kg) of either sex are 70 premedicated with 5 mg/kg intramuscular (IM) xylazine hydrochlolide (Miles Pharmaceuticals, Shawnee Mission, Kans.), and 0.1 mg/kg subcutaneous (SC) atropine sulfate (Lyphomed, Deerfield, Ill.) fifteen minutes prior to the induction of anesthesia. Anaesthesia is induced with 40 mg/kg IM ketamine hydrochloride (Fort Dodge Laboratories, Fort Dodge, Iowa) and 5 mg/kg IM acepromazine maleate (Aveco Company, Inc., Fort Dodge, Iowa). Additional doses of ketamine hydrochloride are administered as necessary to maintain anesthesia. For survival studies, 100,000 U penicillin G (Apothecon of Bristol-Myers Squibb, Princeton, N.J.), is administered IM perioperatively. The skin over the femoral arteries is infiltrated with 1% lidocaine (Astra Pharmaceuticals, Inc., Westborough, Mass.), and the common femoral arteries are exposed from the inguinal ligament to the superficial femoral artery. Arteries are cleared of connective tissue, side branches are ligated, and the superficial femoral artery is suspended with silk ties. A 1.5-to-2.0 cm length of femoral artery is isolated from the circulation proximally and distally with neurosurgical microaneurysm clips. The superficial femoral artery is cannulated with a S-triethylenetetramine-BSA coated 2F Fogarty balloon catheter (American Edwards Laboratories, Santa Ana, Calif.), that is passed into the isolated segment of femoral artery. The balloon is inflated with sufficient air to generate slight resistance and withdrawn three times. The contralateral femoral artery is prepared identically as an appropriate control, i.e., using a balloon catheter coated with underivatized BSA. Following removal of the balloon catheter, the superficial femoral artery is ligated and flow re-established. The area of balloon injury is marked by surgical staples in the adjacent muscle fascia. The incision is closed with subcuticular absorbable suture and the animals allowed to recover. In some experiments, a distant control vessel, the right carotid artery, is isolated and harvested without any other manipulation. [00252] Tissue Processing and Analysis: On the 14th postoperative day, animals are euthanized with 120 mg/kg intravenous sodium pentobarbital (Anpro Pharmaceuticals, Arcadia, Calif.), and the abdominal aorta and inferior vena cava interrupted by silk ties. A 7F plastic cannula is inserted into the abdominal aorta and the vessels perfused clear with saline followed by fixation at 100 mm Hg pressure with 10% buffered formalin. The vessels are stored in 10% buffered formalin and the samples paraffin-embedded and microtome-sectioned. Six sections are made along the length of each injured segment of vessel and stained with Verhoeff's stain for elastic tissue. The areas within the lumen, internal elastic membrane, and external elastic membrane are measured by a blinded observer using computerized digital planimetry (Zeiss, West Germany). The areas within the lumen, internal elastic membrane and external elastic membrane are analyzed. Sections with obstructive thrombus impairing analysis are discarded. 71 [00253] In a separate set of animals, vessels are perfusion-fixed with 10% buffered formalin seven days after injury and processed for analysis of proliferating cells within 12 hours. Sections are stained for proliferating cell nuclear antigen (PCNA) and adjacent sections are stained with hematoxylin and eosin. Five representative sections from each segment are examined. Total nuclei are counted from the hematoxylin and eosin slides and percent PCNA positive cells are defined as the number of PCNA-positive nuclei divided by the total number of nuclei multiplied by 100. [00254] Statistics: Treatments are administered in a paired fashion with one femoral artery cannulated with an anti-connexin agent-BSA coated balloon catheter while the other femoral artery is cannulated with an underivatized BSA coated balloon catheter. Data is tested for normality using appropriate statistical methods, for example, the Kolmogorov-Smimov algorithm and for equal variance with the Levene Median test. Normally distributed variables are compared using, for example, the paired t-test and non-normally distributed variables using, for example, the Wilcoxon sign-ranks test or the Mann-Whitney rank-sum test. Non-paired data are compared using, for example, an independent t-test. Statistical significance is accepted if the null hypothesis is rejected with P<0.05. [00255] Anti-Connexin Agent-BSA Effect on Platelet Binding to Injured Vessel: Platelet adhesion to the injured arterial surface has been reported to be important in the proliferative response to injury. Accordingly the effects of anti-connexin agent-BSA on platelet deposition after balloon injury are investigated. Platelet deposition is assessed at the site of cannulation with anti-connexin agent-BSA coated balloon catheter, and compared to that at the site of cannulation with an underivatized BSA coated balloon catheter. Decreased platelet deposition at the site of cannulation with anti-connexin agent-BSA coated balloon catheter is indicatitve of ameliorated tissue damage and/or enhanced tissue repair. [00256] Anti-connexin agent-BSA Effects on Neointimal Proliferation: Neointimal proliferation after local delivery of anti-connexin agent-BSA and appropriate controls are evaluated by comparing absolute neointimal area and neointima/media ratios. The absolute neointimal area and neointima/media ratio at the site of cannulation with an anti-connexin agent BSA coated balloon catheter is assessed and compared to a neointimal area and neointima/media ratio at the site of cannulation with an underivatized BSA coated balloon catheter. A decrease in neointimal area or reduction in the neointima/media ratio is indicative of an inhibition of neointimal proliferation and of amelioration of tissue damage and/or enhanced tissue repair. 72 [00257] Anti-connexin agent-BSA Effects on Cellular Proliferation: Mouse monoclonal antibody staining against PCNA is used to assay the degree of Si-phase activity at 7 days after injury. At this time, the percent of proliferating cells is assessed in vessels cannulated with an anti-connexin agent-BSA coated balloon catheter and in vessels cannulated with an underivatized BSA coated balloon catheter. Histological assessment determines the cellular populations undergoing proliferation. [00258] These experiments are directed to the effect on neointimal proliferation and amelioration of tissue damage and/or enhanced tissue repair by localised delivery of an anti connexin agent by, for example, the coating of a balloon catheter with anti-connexin agent-BSA. [00259] The endothelium is reported to be essential for vascular integrity, control of thrombosis, (Clowes et al., Lab. Invest. 49:327-333, 1983); (Rees et al., Proc. Natl. Acad. Sci. USA. 86:3375-3378, 1989) and the regulation of intimal growth (Kubes et al., Proc. Natl. Acad. Sci. USA, 88:4651-4655, 1991), and has been proposed to be important in the local control of vascular smooth muscle growth. Balloon angioplasty reportedly removes the endothelium from arterial smooth muscle, and these endothelial functions can often be lost during the procedure. In particular, removal of the endothelium and damage to the smooth muscle cells have been reported to be associated with intimal proliferation (McNamara et al., Biochem. Biophys. Res. Commun., 193:291-296, 1993). The mechanism for this response is complex and reportedly involves platelet deposition and activation, cytokine elaboration, smooth muscle cell migration and proliferation, and extra-cellular matrix production. It has been reported that after balloon injury, the endothelium rcgcncrates rapidly but is often dysfunctional, (Saville, Analyst 83:670 672, 1958). [00260] A limitation of neointimal proliferation after a single, local administration of an anti connexin agent is indicative of amelioration of tissue damage and/or enhanced tissue repair. Anti-platelet activity may explain such findings. Inhibition of platelet binding has been said to result in many effects that are likely to reduce the proliferative response after injury. For example, platelet adhesion and aggregation is said to be associated with the release of PDGF, basic fibroblast growth factor, epidermal growth factor, and transforming growth factor-p, potent stimuli for smooth muscle cell proliferation and matrix production. [00261] There may additionally or alternatively be a direct effect on vascular smooth muscle gene expression, migration, proliferation or synthesis of extracellular matrix. Such an effect may be in addition to an amelioration of tissue damage and/or enhancement in tissue repair by, for example, restoration of normal tissue stem cell responses. 73 [00262] It has been reported that the mechanical removal of the endothelium abolishes the vasodilator responses to endothelium-dependent vasoactive stimuli, while leaving the vasoconstrictor effects of agonists to smooth muscle unopposed (Furchgott Zawadzki, Nature 288:373-376 (1980). This process reportedly occurs with balloon angioplasty especially at sites where platelet thrombus is noted (Uchida et al., Am. Heart. J., 117:769-776 (1989); Steele et al., Circ. Res., 57:105-112 (1985). The strategy of administration of an anti-connexin agent as therapy for, for example, acute thrombotic phenomena and restenosis following angioplasty is supported by results indicating an amelioration of tissue damage and/or enhancement in tissue repair. EXAMPLE 2 Preparation and Use of an Anti-connexin Agent Coated Medical Device for Ameliorating Tissue Damage and/or Enhancing Tissue Repair [00263] The following experiment is directed to application of anti-connexin agents to coated artificial surfaces, such as, for example, synthetic vascular graft material, or stents, for use in ameliorating tissue damage and/or enhancing tissue repair. [00264] First, dacron grafts and cardiac catheters are coated with a functionalized anti connexin agent, such as for example, anti-connexin agent-bovine serum albumin (BSA). In three separate experiments, an identical pair of 6 mm (internal diameter) knitted dacron grafts, 5 cm in length, are prepared for surgical placement in the transected carotid arteries of six anesthetized dogs. For each experiment, three control dogs receive grafts coated in underivatized BSA, while for each of the three trial dogs, one graft is soaked in 5% BSA and the other graft is soaked in 5% BSA combined with 0.5 mM anti-connexin agent producing, anti-connexin agent-BSA, an example of a functionalized anti-connexin agent protein, for one hour prior to insertion, and then rinsed in saline. The grafts are sutured in place with a continuous 6-0 proline suture. [00265] Following graft insertion, the dogs are observed for two months. [00266] Histological examination of the site of insertion is performed at the end of the two month period. Amelioration of tissue damage or enhanced tissue repair is evidenced by, for example, the appearance of normal vascular epithelial cells at the site of graft insertion. Tissue repair at the site of anti-connexin agent-BSA-coated graft insertion is compared to that at the site of underivatized, BSA-coated graft insertion. [00267] Evidence of amelioration of tissue damage and/or enhanced tissue repair at the site of anti-connexin agent-BSA coated graft insertion compared to that at the site of underivatized BSA-coated graft insertion is shown by amelioration of tissue damage and/or enhanced tissue 74 repair at the site of insertion of the synthetic grafts treated with anti-connexin agent-BSA during exposure of the graft to circulating blood over a period of two months. EXAMPLE 3 Application of Anti-Connexin Agents to Damaged Vascular Surfaces to Ameliorate Tissue Damage and/or Enhance Tissue Repair [00268] The following experiment is directed to application of anti-connexin agents to damaged vascular surfaces, for example, arterial surfaces, to ameliorate tissue damage and/or enhance tissue repair. [00269] In five anesthetized dogs, both carotid arteries are exposed. Two 3 FR USC1 catheters are prepared for arterial implantation. One catheter is soaked in a 5% BSA solution for 12 hours, while the other is soaked in a 5% BSA solution which also contains 1 mg/ml of test anti-connexin agent. One each of the two coated catheters is placed randomly in the right or left carotid artery of the dog through a small incision sealed with a 6-0 proline suture. The catheters are advanced for 5 cm into the arterial lumen. Following catheter insertion, the dogs are observed for two weeks. [00270] Histological examination of the site of insertion is performed at the end of the two week period. Lessened tissue damage, and/or tissue repair, is evidenced by, for example, the appearance of normal vascular epithelial cells at the site of catheter insertion. Tissue at the site of anti-connexin agent-BSA coated catheter insertion is compared to that at the site of underivatized BSA-coated catheter insertion. [00271] Evidence of enhanced tissue repair and/or amelioration of tissue damage at the site of anti-connexin-BSA coated catheter insertion compared to that at the site of underivatized BSA-coated catheter insertion is shown by enhanced tissue repair and/or amelioration of tissue damage at the site of insertion of the catheter treated with anti-connexin agent-BSA during exposure of the catheter to circulating blood over a period of two weeks. EXAMPLE 4 Determination of Tissue Damage Using an Anti-connexin Agent Treated Medical Device in a Pig Model [00272] The following experiment is directed to determining the tissue damage using a treated medical device in a pig model. [00273] Pigs are subjected to coronary balloon-injury using standard methods. Prior to balloon injury, an angiogram is performed. Thereafter, in trial pigs, a test anti-connexin agent BSA coated balloon catheter, for example, is used for balloon injury, whereas in control pigs, an 75 underivatized BSA coated balloon catheter is used. The balloon of the catheter is inflated for 15 min, then deflated and the catheter is removed. Another angiogram is performed 30 minutes after injury to determine the degree of spasm. Coronary catheters are placed in the coronary ostea, radiocontrast is infused into the coronary arteries and measurements are made of the degree of so-called "recoil spasm" that exists at the point of angioplasty. The degree of spasm or recoil is defined quantitatively, again using the computer-driven quantitative coronary angiography algorithm that compares the segment at the site of balloon injury with a proximal segment that is uninjured as a reference standard. All catheters are then removed and incision sites repaired. The animals are awakened and maintained with normal chow diets over the next four weeks. At the end of that period of time, the animals are again sedated, undergo coronary angiography to determine coronary stenoses at the site of angioplasty. Catheters are placed in the coronary ostea and radiocontrast fluid is infused. The angiograms are recorded and subsequently processed by a computer-driven quantitative coronary angiography algorithm to determine lumen diameter. The degree of stenosis represents the percentage reduction in the lumen diameter compared with a reference segment proximal to the area of stenosis using standard methods. The animals are euthanized by an overdose of pentobarbital. Their coronary arteries are perfusion fixed with formalin at 100 mm Hg of perfusion pressure, harvested and sectioned for quantitative morphometric assessment of the lumen diameter, the neointimal dimension and cross-section, as well as the neointimal area. The arteries are stained with hematoxylin and eosin. The neointima to lumen diameter ratio is determined and is compared between trial and control animals. EXAMPLE 5 Determination of Effect on Tissue Damage and/or Tissue Repair Using an Anti-connexin Agent Coated Medical Device [00274] This experiment is directed to coating a Palmaz-Schatz stent with an anti-connexin agent to reduce the degree and severity of neointimal hyperplasia leading to restenosis. Palmaz Schatz stents are dip-coated in 800-10OOpM test anti-connexin agent-BSA, for example, or underivatized BSA three times for 10 minutes followed by 10 minutes of air drying time. One test anti-connexin agent-BSA coated and one underivatized BSA-coated stent is placed under sterile conditions in the carotid arteries of 10 pigs, one in each carotid artery. They are followed for 28 days and then the carotid arteries are removed. They are examined histologically for the degree of neointimal hyperplasia, and tissue damage/repair. Tissue repair is evidenced by, for example, the appearance of normal vascular epithelial cells at the site of insertion of the stent. 76 Tissue damage/repair at the site of test anti-connexin agent-BSA coated stent insertion is compared to that at the site of underivatized BSA-coated stent insertion. [00275] Evidence of amelioration of tissue damage and/or enhanced tissue repair at the site of test anti-connexin agent-BSA coated stent insertion compared to that at the site of underivatized BSA-coated stent insertion shows that during exposure of the stent to circulating blood, therc is amelioration of tissue damage and/or enhanced tissue repair at the site of insertion of the stent coated with anti-connexin agent, and that delivery of an anti-connexin agent is able to ameliorate tissue damage enhance tissue repair. EXAMPLE 6: Method of coating pharmaceutical agents onto sutures [00276] A 4-0 VICRYL (Polyglactin 910) Suture (Ethicon, Somerville, N.J.) is coated with suitable anti-connexin agent and gelatin. The coating solution comprises of 4 ml gelatin solution and 2 ml of anti-connexin agent solution. The gelatin component is prepared by heating a 10 wt % solution of medical grade soluble bovine collagen (Semed-S, Kensey-Nash, Exton, Pa.) to 800 C. for 10 minutes followed by incubation at 370 C. The anti-connexin agent, e.g., an anti connexin 43 agent (for example, a connexin 43 antisense ODN, or an anti-connexin 43 peptide or peptidomimetic, such as one that blocks or inhibits hemichannel opening), is prepared at suitable concentrations, such as, for example, 10, 3, 0.6, and 0 pg/ml. The resulting concentrations in the coating solutions can then be determined. The coating solutions are kept at 37* C. until use. Prior to coating, the sutures are pretreated with a bath of 70% ethanol solution for 10 minutes, followed by a wash with saline. The suture is then placed in the coating solution and incubated at 370 C. for 30 minutes with gentle agitation. The suture is then removed from the solution and is then air-dried overnight. [00277] The concentration of the anti-connexin agent on the suture is quantified by an ELISA method. The anti-connexin agent is first eluted from a 4 cm segment of suture in 2 ml of 6M Urea solution (75 mM NaH2PO 4, pH 2.7) at 37* C for 1 hour. The elution solutions are analyzed by a sandwich ELISA assay that detects the presence of the anti-connexin agent. The concentration of the anti-connexin agent on the suture is measured in pig/cm. EXAMPLE 7 [00278] A 0 ETHIBOND EXCEL Polyester Suture (Ethicon, Somerville, N.J.) is coated with anti-connexin agent and gelatin in a similar manner as described in Example 6. An anti-connexin agent solution is concentrated to appropriate concentration (in mg/ml) with a centrifugal filter device (e.g. Centriplus YM-10, Regenerated Cellulose 10,000 MWCO, Amicon Bioseparations). 77 The coating solution comprises of 0.5 ml concentrated anti-connexin solution and I ml 10 wt % gelatin solution. The concentration of anti-connexin solution on the coated suture, as quantified by ELISA, is then measured. [00279] Sutures are pulled through a sample of goat ACL tissue to evaluate if any of the anti connexin agent coating is sheared off during its use. The concentration of anti-connexin agent post-surgcry is measured. If appropriate concentration is obtained, it is an indication that the gelatin is effective in maintaining the anti-connexin agent on the suture even while passing through tissue. [00280] Preferred anti-connexin agents for sutures areanti-connexin 43 agent, particularly connexin 43 antisense (e.g., ODN) molecules, or an anti-connexin 43 peptide or peptidomimetic, such as one that blocks or inhibits hemichannel opening), or both together, EXAMPLE [00281] A 0 Plain Surgical Gut Suture (Ethicon, Somerville, N.J.) is coated with anti connexin agent. The coating solution comprises of I ml anti-connexin agent solution concentrated to the appropriate concentration (in mg/ml) with a centrifugal filter device (e.g. Centriplus YM-10, Regenerated Cellulose 10,000 MWCO, Amicon Bioseparations). The gut suture is pretreated in a bath of 200 mM NaH 2PO4 (pH 11.2) for 10 minutes followed by a wash in PBS prior to coating. The concentration of the anti-connexin coating on the coated gut suture is then quantified by ELISA assay. EXAMPLE 9 [00282] A partially resorbable composite suture (e.g., 2 ORTHOCORD Orthopaedic Suture, DePuy Mitek, Raynham, Mass.) is coated with anti-connexin agent and gelatin in a similar manner as described in Example 6. The coating solution comprises of suitable volume of anti connexin agent solution at a desired concentration (e.g. 3.5 mg/ml and 1.4 ml 10 wt % gelatin solution). The concentration of the anti-connexin agent on the coated partially resorbable composite suture is then quantified by ELISA (e.g. tg/cm).
