Abstract
Description
Die Erfindung betrifft eine Dilatationssonde und ähnliche/zusätzliche Vorrichtungen für die Behandlung erkrankter Leitungsbahnen wie der stenosierenden Arteriosklerose.The invention relates to a dilatation probe and the like / additional Devices for the treatment of diseased conduits such as the stenosing arteriosclerosis.
Große Bedeutung für die Herzinfarktentstehung und als Todesursache hat die stenosierende Herzkranzschlagadersklerose. Seit 12 Jahren wird für dabei erforderliche Gefäßdilatationen die percutane transluminale Angioplastie mit fast 2 Meter langen und kaum 2 Millimeter dicken Ballonkathetern durchgeführt. Bei solchen aufwendigen zweilumigen Kathetern bildet vorn der aus einer Kunststoffolie bestehende Ballon die dickste und zudem auch eine raue Stelle, wodurch das Vorbringen des Katheters besonders in Leitungsbahnstenosen erschwert sein muß. Mit etwa 10 atü wird zur Angioplastie der Ballon schlagartig über den zweiten dünnen Kanal dieses speziellen Katheters aufgedehnt. Nicht selten ergeben sich verständlicherweise dabei Gefäßwandblutungen, manchmal Einrisse, so daß erneut Stenosen beispielsweise durch Thrombenbildung an solcher Gefäßstelle entstehen oder sogar eine herzchirurgische Operation angeschlossen werden muß. Ziel bei Stenocardie/Ischämie des Coronarsystems sollte auf weite Sicht sein, das auch zahlreiche Anastomosen (Querverbindungen) besitzende Coronarsystem völlig unblutig zur Verbesserung der Durchströmung und Ernährung der Herzmuskulatur zu behandeln. Beispielgebend für die unblutige Therapie ist die Stoßwelleneinbringung der nun schon zahlreichen eingesetzten Lithotripter.Of great importance for the development of heart attacks and as a cause of death the stenosing coronary artery sclerosis. For 12 years the percutaneous transluminal for the necessary vascular dilatation Angioplasty with almost 2 meters long and barely 2 millimeters thick Balloon catheters performed. With such complex two-lumen The balloon consisting of a plastic film forms catheters at the front the thickest and also a rough spot, which makes the argument of the catheter must be difficult, especially in conduction stenoses. The angioplasty of the balloon is abruptly over the second thin channel of this special catheter expanded. Not Understandably, there is rarely vascular wall bleeding, sometimes tears, so that stenoses again, for example Thrombus formation at such a vascular site or even one cardiac surgery must be connected. Aim at Stenocardia / ischemia of the coronary system should be in the long run, that also possesses numerous anastomoses (cross-connections) Coronary system completely bloodless to improve the flow and to treat heart muscle nutrition. Exemplary for the bloodless therapy, the shock wave introduction is now already used numerous lithotripters.
Mit DE P 33 16 186 wird über eine Vorrichtung zum Einbringen mechanischer Schwingungen des Niederfrequenzbereiches in tiefere Körperschichten und Organe berichtet, mit der berührungslos über den Brustkorb die Begünstigung der Rückemulsion von übermäßig bei der Coronarsklerose abgelagerter Lipide aus der Innenschicht der Arterienwandungen zu erreichen ist. Die in das Coronarsystem über den Brustkorb eingebrachte Energie, die zur Schädigung gesunden Gewebes nicht führen darf, ist gering und erforderlich ist, möglichst am Ort der Erkrankung selbst eine Fokussierung derartiger Wellenenergie zu erreichen. Selbstfokussierung in Körpern wie in Leitungsbahnen eines Patienten ist nach neueren Er kenntnissen möglich wie in DE 35 17 020, wenn am Ort der Erkrankung verstreut zahlreiche feine Gasblasen bzw. sogenannte Microspheres vor handen sind. Bekannt ist, daß Microspheres zur Zerstörung anorganischer Werkstoffe benutzt werden wie beispielsweise, um bereits verfestigten Knochenzement durch Stoßwellen nach Schenkelhalsbrüchen zu zerstören (Firma Dornier).With DE P 33 16 186 is via a device for introducing mechanical vibrations of the low frequency range in deeper body layers and organs reports with the non-contact on the chest favor the back emulsion of excessively deposited in coronary sclerosis Lipids can be reached from the inner layer of the artery walls. The energy introduced into the coronary system via the rib cage, the must not lead to damage to healthy tissue is minor and is necessary, if possible at the location of the disease itself To achieve focusing of such wave energy. Self-focusing in bodies as in a patient's pathways, according to recent Er knowledge possible as in DE 35 17 020 if at the site of the disease scattered numerous fine gas bubbles or so-called microspheres are available. It is known that microspheres for the destruction of inorganic Materials are used such as to solidify already Bone cement destroyed by shock waves after fractures of the femoral neck (Dornier company).
Der Erfindung liegt die Aufgabe zugrunde, zur Behandlung verschiedener Erkrankungen in Leitungsbahnen des Körpers in den Körper von außen gesteuert berührungslos eingebrachte Wellenenergie/Stoßwellenenergie im Bereich der Erkrankung so zu verstärken, daß ausreichend physikalische Kräfte am Ort der Erkrankung zur Verfügung stehen, um eine schonende und dennoch effiziente Behandlung vornehmen zu können beispielsweise der stenosierenden Coronarsklerose wie auch eines Darmkrebses.The invention has for its object to treat various Diseases in pathways of the body to the body from the outside controlled contactlessly introduced wave energy / shock wave energy in the area of the disease so that it is sufficiently physical Forces at the site of the disease are available to be gentle and still be able to perform efficient treatment, for example stenosing coronary sclerosis as well as colon cancer.
Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Die weitere Ausgestaltung der Erfindung ist den Unteransprüchen, der Zeichnung und deren Beschreibung zu entnehmen. This task is performed in a generic device by the characterizing features of claim 1 solved. The further embodiment of the invention is the dependent claims Drawing and their description can be found.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß eine schonende Kombinationstherapie verschiedener Er krankungen in/von Leitungsbahnen des Körpers wie vor allem der klinisch so bedeutsamen stenosierenden Coronarsklerose eingesetzt werden kann. Die eine Komponente dieser Therapie besteht in der berührungslosen Einbringung von Wellenenergie, gegebenenfalls auch mit Stoßwellen in den Krankheitsherd, ohne daß die Körperober fläche oder gesundes Gewebe beschädigt wird in der Art der Lithotripsie. Die genaue Fokussierung der Stoßwellen auf eine sich dauernd bei der Herzaktion bewegenden Stenose bei fortgeschrittener Coronarsklerose ist aus mehreren technischen Gründen kaum oder nicht möglich. Für die von außen vorgebrachte Wellenenergie kann aber in der erkrankten Leitungsbahn selbst, und entsprechend auch in einer stenosierten Coronarie die Selbstfokussierung der von außen eingebrachten Wellen energie erreicht werden. Statt des Ballonkatheters ist nun die weniger aufwendige auch seitlich stauchbare, sich innerhalb der Stenose ver jüngende Dilatationssonde percutan transluminal vergleichsweise zum Ballonkatheter schonend auch durch die Stenose einer Coronar-Arterio sklerose vorzubringen. Da diese Dilatationssonde zahlreiche Luft bläschen neben dem axialen Führungsdraht in der gummiartigen Grund substanz besitzt, ist in diesem von Kardiologen relativ leicht herbei zuführenden Zustand die Selbstfokussierung von von außen vorgebrachter Wellenenergie im Krankheitsherd/Krankheitsbereich zur Rückemulsion von Lipiden und Abdrängung/Beseitigung der Stenose ohne weiteres zu erreichen. Analog kann auch in anderen Leitungsbahnen zur Selbst fokussierung vorgegangen werden, wie beispielsweise bei einem Krebs des Verdauungstraktes. Der Patient mit Darmkrebs hätte somit zur Selbstfokussierung von Stoßwellen/Wellenenergie relativ geringer Intensität vor der Applikation der Stoßwellen, die gradlinig verlaufen und besser ausrichtbar sind als andere Wellen, einen Brei mit zahl reichen Gasbläschen in der Art von Microsphereses einzunehmen.The advantages achieved with the invention are in particular in that a gentle combination therapy of different Er diseases in / from body conduits, especially the clinically important stenosing coronary sclerosis can be. One component of this therapy is the contactless introduction of wave energy, if necessary also with shock waves in the focus of the disease, without the upper body Area or healthy tissue is damaged in the way of lithotripsy. The exact focus of the shock waves on one is constantly at the Cardiac action-moving stenosis in advanced coronary sclerosis is hardly or not possible for several technical reasons. For the externally applied wave energy can, however, in the diseased Cableway itself, and accordingly also in a stenosed Coronary the self-focusing of the waves brought in from outside energy can be achieved. Instead of the balloon catheter, there is now less complex also laterally compressible, ver ver within the stenosis recent dilation probe percutaneously transluminally comparable to Balloon catheter also gentle through the stenosis of a coronary artery to bring sclerosis. Because this dilation probe has lots of air blister next to the axial guidewire in the rubbery base possesses substance, is relatively easy for cardiologists self-focusing from the outside Wave energy in the focus of the disease / disease area for the back emulsion of Lipids and displacement / elimination of the stenosis are easy to do to reach. Analog can also be used in other conduits focus, such as cancer of the digestive tract. The patient with colon cancer would therefore have Self-focusing of shock waves / wave energy relatively less Intensity before the application of the shock waves, which run in a straight line and can be aligned better than other waves, a pulp with a number rich gas bubbles in the manner of microsphereses.
Vergleichsweise zum differenziert aufgebauten Ballonkatheter mit zwei Kanälen und Führungsdraht ist die einen einheitlichen Körper be sitzende Dilatationssonde wenig aufwendig. Für ihre Herstellung sind erforderlich eine biegsame stauchungsfeste vor allem aus Metall be stehende Achse, darum eine langgestreckte gummiartige Grundsubstanz, in der verstreut zahlreiche Luft- oder Gasbläschen zur Absorbtion der Wellenenergie mit Rückschlag sozusagen auf den Krankheitsherd wie zur Beseitigung von Stenosen vorhanden sind. Um das Gleiten dieser Sonde in der Leitungsbahn zu verbessern, wird es zweckmäßig sein, die Ober fläche mit einer feinen gummiartigen Schicht zu glätten. Auch andere herkömmliche katheterartige Instrumente können in dieser Weise für die Selbstfokussierung von Wellenenergie umgerüstet werden, beispielsweise indem ein Katheter mit Düsenkopf vorn axial den für die Funktion der Selbstfokussierung von Wellenenergie wichtigen Teil einer Dilatations sonde mit zahlreichen Luftbläschen trägt. Ein solches langgestrecktes im Lumen einer erkrankten Leitungsbahn vorgebrachtes Instrument er möglicht somit dem Untersucher Medikamente zu injizieren, Blut oder einen anderen Körpersaft zu entnehmen und außerdem die Selbstfokussierung von Wellenenergie im Krankheitsbereich vorzunehmen. An einem solchen Katheter vorhandene nach hinten gestellten Düsen ermöglichen auch durch zur Seite wie nach hinten austretendem Fluid eine Abdrängung der Leitungsbahnwand wie einen mäßigen Vorschub der Sonde bzw. des Katheters. Fraglos ist bei genanntem Aufbau eine Dilatationssonde besser als der vordere Teil eines Ballonkatheters (Grüntzig) durch eine Leitungsbahnstenose hindurchzubringen. Es zeigtCompared to the differentiated balloon catheter with two Channels and guidewire is the one unified body sedative dilatation probe not very expensive. For their manufacture required a flexible, compression-resistant, especially metal standing axis, therefore an elongated rubber-like basic substance, in the scattered numerous air or gas bubbles for the absorption of the Wave energy with a setback, so to speak, on the focus of the disease as for Eliminating stenoses are present. About the sliding of this probe to improve in the conduit, it will be appropriate to the waiter smooth the surface with a fine rubber-like layer. Others too Conventional catheter-like instruments can be used for the Self-focusing of wave energy can be converted, for example by a catheter with a nozzle head at the front for the function of the Self-focusing of wave energy is an important part of a dilation probe with numerous air bubbles. Such an elongated one Instrument brought up in the lumen of a diseased conduit thus allows the examiner to inject medication, blood or to take another body juice and also the self-focus of wave energy in the disease area. On one Catheters provided to the rear also enable due to fluid exiting to the side and backwards the track wall like a moderate advance of the probe or Catheters. A dilatation probe is unquestionable given the structure mentioned better than the front part of a balloon catheter (Grüntzig) to bring a stenosis through. It shows
