Description

La présente invention est relative à un outil de mise en place d'une endoprothèse autoexpansible pour organe tubulaire humain ou animal. The present invention relates to a setting tool of a self-expanding endoprosthesis for human or animal tubular member. Elle s'applique en particulier au traitement des anévrismes et aux dilatations par voie endoluminale. It applies in particular to the treatment of aneurysms and expansions by endoluminal.

Les endoprothèses autoexpansibles sont généralement constituées d'un simple treillis métallique autoexpansible. The self-expanding stents are generally comprised of a single self-expanding wire mesh. Après une dilatation transluminale, elles sont introduites, au moyen d'une sonde, par voie endoluminale, puis libérées. After transluminal expansion, they are introduced by means of a probe, for endoluminal and then released.

L'invention a pour objet un outil de mise en place d'une endoprothèse autoexpansible telle que définie ci-dessus. The invention relates to a setting tool of a self-expanding stent as defined above. Cet outil comprend This tool includes
- un conduit-guide pourvu à son extrémité distale d'une tulipe sécable de logement de l'endoprothèse à l'état contracté; - a guide conduit provided at its distal end with a breakable tulip housing of the stent in the contracted state; et and
- des moyens pour découper la tulipe en plusieurs pétales. - means for cutting the tulip into several petals.

Suivant un mode de réalisation, lesdits moyens comprennent des fils de découpe de la tulipe reliés à une poignée d'actionnement. According to one embodiment, said means comprise the tulip cutting son connected to an actuating handle.

- la Figure 7 illustre la dilatation correspondante de l'endoprothèse. - Figure 7 illustrates the corresponding expansion of the stent.

L'endoprothèse 1 représentée aux Figures 1 et 2 est constituée d'un treillis tubulaire 2 noyé dans un film 3. The stent 1 shown in Figures 1 and 2 consists of a tubular mesh 2 embedded in a film 3.

Le treillis 2 est constitué d'acier inoxydable de qualité biocompatible. The mesh 2 consists of biocompatible stainless steel quality. Il peut être réalisé par tissage ou tricotage d'un fil, déploiement axial d'un tube, ou par toute autre technique appropriée. It can be produced by weaving or knitting a yarn axial deployment of a tube, or by any other suitable technique. I1 est plastiquement déformable, c'est-à-dire qu'il possède une première forme stable de petit diamètre, représentée à la Figure 1, dans laquelle les mailles forment des losanges allongés parallèlement à son axe, et une seconde forme stable de diamètre très agrandi et de plus courte longueur, représentée à la Figure 2, dans laquelle les mailles forment des losanges allongés dans le sens circonférentiel. I1 is plastically deformable, that is to say it has a first stable shape of smaller diameter, shown in Figure 1, wherein the meshes form elongated diamond parallel to its axis, and a second stable diameter greatly enlarged and shorter in length, shown in Figure 2, in which the meshes form elongated diamonds in the circumferential direction.

Le treillis 2 est entièrement noyé dans un film 3 d'une matière extensible et étanche aux liquides qui en remplit les mailles. The mesh 2 is completely embedded in a film 3 of an expandable and impermeable material liquid which fills the meshes. L'extensibilité de cette matière est suffisante pour que le film 3 puisse suivre la déformation du treillis 2 de son état contracté à son état dilaté sans déchirure ni décollement, malgré la déformation des mailles du treillis. The extensibility of the material is sufficient for the film 3 can follow the deformation of the mesh 2 to its contracted state to its expanded state without tearing or peeling, despite the deformation of the lattice mesh. Des matières appropriées sont un élastomère biocompatible, qui peut être un caoutchouc naturel ou synthétique, ou bien un polymère biocompatible tel qu'un polyuréthanne. Suitable materials are a biocompatible elastomer, which may be a natural or synthetic rubber, or a biocompatible polymer such as polyurethane.

L'enrobage du treillis 2 par le film 3 peut être obtenu par des techniques de co-extrusion ou de trempage, après dégraissage du métal et son traitement par une substance primaire d'adhérence. The coating of the mesh 2 with the film 3 can be obtained by co-extrusion or dipping procedures, after degreasing the metal and its treatment with an adhesion primer substance.

On obtient donc, à l'état dilaté (Figure 2), un tronçon tubulaire étanche aux liquides qui peut être utilisé comme endoprothèse ou "stent" après une dilatation transluminale. is thus obtained, in the expanded state (Figure 2), a sealed tubular section to liquids which may be used as a stent or "stent" after transluminal dilatation. Cette endoprothèse ne traumatise pas les tissus et ne crée pratiquement pas de turbulences dans le flux sanguin, puisque les tissus et le sang sont au contact d'un surface pratiquement lisse en élastomère ou en polymère. This stent does not traumatise the tissue and creates practically no turbulence in the blood flow, as the tissues and the blood are in contact with a substantially smooth surface elastomer or polymer.

Du fait de son étanchéité, l'endoprothèse peut être utilisée pour traiter par voie endoluminale un anévrisme, en la faisant ponter l'anévrisme, chacune de ses extrémités s'appliquant radialement contre la paroi intérieure d'un tronçon d'artère sain adjacent à l'anévrisme. Because the seal, the stent may be used to treat an aneurysm by endoluminal way, by making bridging the aneurysm, each of its ends applying radially against the inner wall of a healthy artery section adjacent the aneurysm.

Dans un autre mode de réalisation, illustré aux Figures 3 à 7, le treillis 2 de l'endoprothèse 1A est autoexpansible, ce qui s'obtient de façon classique par utilisation d'un acier inoxydable ayant des propriétés de ressort. In another embodiment, shown in Figures 3-7, the mesh 2 of the stent is self-expanding 1A, which is obtained in conventional manner by use of a stainless steel having spring properties.

Pour mettre en place l'endoprothèse lA, on la comprime radialement jusqu a sa configuration de la To insert the stent lA, it compresses radially up to its configuration
Figure 1, qui n'est pas stable, et on l'introduit dans la tulipe d'extrémité 4 d'un outil 5 représenté sur les Figure 1 which is not stable, and is introduced into the end bell 4 of a tool 5 shown in
Figures 3 à 5. Figures 3 to 5.

L'extrémité distale de la tulipe 4 est ouverte et présente trois échancrures 6 à 120C les unes des autres. The distal end of the socket 4 is open and has three indentations 6 to 120C from one another. Son extrémité proximale forme un épaulement intérieur 7 d'où part un conduit de guidage 8. Dans le plan de chaque échancrure 6, un canal 9 formé dans l'épaisseur de paroi du conduit 8 débouche à l'extérieur par des orifices radiaux 10, 11, d'une part près de l'épaulement 7, d'autre part près de l'extrémité proximale du conduit 8. Its proximal end forms an inner shoulder 7 from which a guiding duct 8. In the plane of each recess 6, a channel 9 formed in the wall thickness of the conduit 8 opens to the outside through radial openings 10, 11, first near the shoulder 7 on the other hand near the proximal end of the conduit 8.

On peut également prévoir dans l'épaisseur de paroi du conduit 8, comme représenté, des canaux longitu dinaux 12, 13 d'injection de fluides, qui partent de l'extrémité proximale de ce conduit et débouchent dans la lumière intérieure du conduit 8 près de l'épaulement 7. Can also be provided in the wall thickness of the conduit 8, as shown, the longitu Dinaux channels 12, 13 fluid injection, which extend from the proximal end of the conduit and opening into the inner lumen of the duct 8 near of the shoulder 7.

Dans chacun des trois plans précités, un fil souple 14 passe dans l'échancrure 6. Un brin intérieur 15 de ce fil longe la paroi intérieure de la tulipe 4, traverse un orifice 16 prévu dans l'épaulement 7, pénètre dans l'orifice 10, s'étend le long du canal 9, sort par l'orifice 11 et rejoint une poignée d'actionnement 17 (Figure 3). In each of the above three planes, a flexible wire 14 passes through the notch 6. An inner end 15 of this thread runs along the inner wall of the bell 4, passes through an orifice 16 provided in the shoulder 7, enters the orifice 10, extends along the channel 9 exits through the orifice 11 and reaches an operating handle 17 (Figure 3). Un brin extérieur 18 du fil 14 longe la paroi extérieure de la tulipe, suit le même trajet 19, 11 que le brin 15, et rejoint également la poignée 17. Celle-ci est donc reliée à six brins de fils, et les trois brins intérieurs 15 sont plaqués contre la paroi intérieure de la tulipe par la tendance à l'expansion de l'endoprothèse 1A. An outer strand 18 of wire 14 runs along the external wall of the tulip, follows the same path 19, 11 as the strand 15, and also joins the handle 17. The latter is therefore connected to son six strands, and the three strands interior 15 are pressed against the inner wall of the bell by the tendency to expand the stent 1A.

Pour l'utilisation de l'endoprothèse, après une dilatation transluminale ou pour traiter un anévrisme, l'outil 5 est enfilé sur un guide, introduit à travers la peau et conduit par voie endoluminale jusqu'à l'emplacement désiré. For the use of the stent, after transluminal dilatation or to treat an aneurysm, the tool 5 is threaded onto a guide, introduced through the skin and leads endoluminally to the desired location.

L'opérateur tire alors sur la poignée 17. The operator then pulls on the handle 17.

Celle-ci met les trois fils 15 en tension, et ces fils découpent chacun la tulipe 4 suivant une génératrice. The latter puts the three son 15 in tension, and these son each cut tulip 4 along a generatrix. La tulipe libère donc progressivement l'endoprothèse, laquelle se dilate d'elle-même, comme illustré sur la The tulip therefore progressively releases the stent, which expands by itself, as illustrated in
Figure 6. Lorsque la tulipe est entièrement ouverte, on retire l'outil par traction sur le conduit 8. Figure 6. When the socket is fully open, the tool is withdrawn by pulling on the conduit 8.

A l'état dilaté (Figure 7), on constate que les deux extrémités de l'endoprothèse se sont évasées dTellesmêmes, ce qui procure deux effets avantageux d'une part, l'étanchéité entre 1 'endoprothèse et l'artère est renforcée, et d'autre part, les extrémités 19 des fils du treillis 2 dépassent légèrement du film 3 et constituent autant de pointes d'accrochage de l'endoprothèse dans l'artère. In the expanded condition (Figure 7) shows that the two ends of the stent are flared dTellesmêmes, providing two beneficial effects on the one hand, the seal between one stent and artery is strengthened, and secondly, the ends 19 of the mesh 2 son protrude slightly from the film 3 and are all fastening spikes of the stent in the artery. La stabilité du positionnement de l'endoprothèse est ainsi assurée. The stability of the positioning of the stent is ensured.

D'autres matériaux peuvent être utilisés pour constituer le treillis 2. Par exemple, pour réaliser une endoprothèse autoexpansible, on peut utiliser du fil d'un polymère relativement rigide et à propriétés de ressort tel que le polytétrafluoroéthylène (PTFE), rendu radioopaque. Other materials may be used to form the mesh 2. For example, to achieve a self-expanding stent, one may use wire of a relatively rigid polymer and spring properties such as polytetrafluoroethylene (PTFE), made radiopaque.
