Abstract

Percutaneous vertebral implant (A) for straightening collapsed vertebral plates and to consolidate damaged vertebrae and/or intervertebral spaces, comprises an envelope of biocompatible material, formed as an elongated balloon, or some other shape of balloon, open at one end to allow threading on a carrier.

Description

La présente invention concerne un implant vertébral percutané en la formeThe present invention relates to a percutaneous vertebral implant in the form

d'un ballon destiné à redresser des plateaux vertébraux affaissés, consolider la vertèbre et son dispositif pour l'installer.  a balloon to straighten sagging vertebral trays, consolidate the vertebra and its device to install it.

L'état actuel des matériels à implanter et des procédures d'installation est générateur de 5 fuites veineuses et de complications (embolies pulmonaires).  The current state of the material to be implanted and the installation procedures is generating 5 venous leaks and complications (pulmonary embolism).

Le dispositif selon l'invention permet de remédier à ces inconvénients. II s'agit d'une enveloppe en matériau biocompatible et notamment en silicone sphérique (3) en la forme d'un ballon ouvert à une extrémité pour être monté sur un cathéter (1). Autour du cathéter est placé un coaxial permettant le largage (2). La base du ballon est entourée d'une ligature (4) ou dans une variante d'un clapet anti-retour (5).  The device according to the invention overcomes these disadvantages. It is an envelope of biocompatible material and in particular spherical silicone (3) in the form of a balloon open at one end to be mounted on a catheter (1). Around the catheter is placed a coaxial for the release (2). The base of the balloon is surrounded by a ligature (4) or in a variant of a non-return valve (5).

La mise en place du ballon dans le corps vertébral ou dans l'espace intersomatique se fait au moyen d'une aiguille de 11 ou 13 gauges (1,9 mm) introduite auparavant par voie transpédiculaire. Installé, la ballon est gonflé jusqu'à 13 atmosphères, le ballon est ensuite rempli de ciment biocompatible (polymetacrilate de méthyle), ligaturé ou fermé grâce au clapet évitant les fuites de ciment. Il est ensuite largué pour rester dans la position implantée. Un deuxième ballon controlatéral installé de la même façon permet d'obtenir un redressement des plateaux vertébraux.  The placement of the balloon in the vertebral body or in the intersomatic space is done by means of a needle of 11 or 13 gauges (1.9 mm) previously introduced by transpedicular way. Installed, the balloon is inflated to 13 atmospheres, the balloon is then filled with biocompatible cement (polymetacrilate methyl), ligated or closed thanks to the valve avoiding cement leaks. It is then dropped to stay in the implanted position. A second contralateral balloon installed in the same way allows to obtain a recovery of the vertebral trays.

L'avantage de l'invention et de sa procédure d'implantation est l'absence de fuites veineuses, l'intégration dans les jours qui suivent du silicone et sa bonne tolérance, et le fait que seul le noyau de ciment demeure, permettant de solidifier la vertèbre. En outre, l'invention permet d'éviter la migration du ciment en cours de procédure, de diminuer les phénomènes algiques et de redresser la cyphose vertébrale.  The advantage of the invention and its implantation procedure is the absence of venous leakage, the integration in the following days of the silicone and its good tolerance, and the fact that only the cement core remains, allowing solidify the vertebra. In addition, the invention makes it possible to avoid the migration of the cement during the procedure, to reduce the pain phenomena and to correct the vertebral kyphosis.

Selon les modes particuliers de réalisation: - le ballon peut être équipé à sa base d'un col entouré d'une ligature élastique, - le ballon peut être équipé d'un clapet anti-retour interne occultant l'orifice après remplissage, - le ballon comprend un dispositif porteur sous forme d'une sonde, - la sonde d'introduction comporte un robinet à trois voies à la base pour faire le vide, (6) - le coaxial permet le largage du ballon par coulissage.  According to the particular embodiments: the balloon may be equipped at its base with a collar surrounded by an elastic ligature; the balloon may be equipped with an internal check valve concealing the orifice after filling; balloon comprises a carrier device in the form of a probe, - the introduction probe comprises a three-way valve at the base to evacuate, (6) - the coaxial allows the release of the balloon by sliding.

Le mode opératoire consiste par un abord vertébral par voie transpédiculaire en lombaire et latéro-pédiculaire en dorsal ou encore transpédiculaire en cervical destiné à vérifier l'existence et l'état du retour veineux.  The procedure consists of a vertebral approach by transpedicular approach in lumbar and latero-pedicular in dorsal or cervical transedicular intended to check the existence and the state of the venous return.

L'injection de ciment est satisfaisante lorsque celui-ci respecte une composition adaptée.  The injection of cement is satisfactory when it respects a suitable composition.

En référence à ce dessin, ce dispositif comporte un implant en la forme d'un ballon consistant en une enveloppe en matériau biocompatible et notamment en silicone (3) dont la base est munie d'un orifice et d'un clapet anti-retour (5) ou dans une variante d'un col entouré d'une ligature élastique (4) installée sur un cathéter porteur (1) autour duquel est placé un coaxial (2) permettant le largage par coulissage. Le cathéter porteur est muni à son extrémité d'un robinet à trois voies pour faire le vide (6).  The attached drawing illustrates the invention: FIG. 1 represents in section the device of the invention. With reference to this drawing, this device comprises an implant in the form of a balloon consisting of an envelope of biocompatible material and in particular silicone (3) whose base is provided with an orifice and a non-return valve ( 5) or in a variant of a neck surrounded by an elastic ligation (4) installed on a carrier catheter (1) around which is placed a coaxial (2) for the release by sliding. The carrier catheter is provided at its end with a three-way valve for evacuation (6).

L'implant vertébral est un ballon consistant en une enveloppe en matériau biocompabile et notamment en silicone (3) résistant à une pression de 10 atmosphères de 2 à 3 cm de long et de 5 mm de diamètre environ (gonflé). II peut être introduit dans une aiguille de 11 gauges. II peut être constitué d'une ou de plusieurs sphères en matériau biocompatible et notamment en silicone de formes différentes en vue de réduire certains tassements ou cyphoses vertébrales.  The vertebral implant is a balloon consisting of an envelope of biocompatible material and in particular silicone (3) resistant to a pressure of 10 atmospheres of 2 to 3 cm long and about 5 mm in diameter (inflated). It can be introduced into an 11-gauge needle. It may consist of one or more spheres of biocompatible material and in particular silicone of different shapes in order to reduce certain settlements or vertebral kyphosis.

L'orifice à la base est équipé d'un col entouré d'une ligature élastique (4) et dans une variante non illustrée d'un clapet anti-retour (5).  The orifice at the base is equipped with a collar surrounded by an elastic ligature (4) and in a non-illustrated variant of a non-return valve (5).
