Abstract
Description
La présente invention est relative à un outil de mise en place d'une endoprothèse autoexpansible pour organe tubulaire humain ou animal. Elle s'applique en particulier au traitement des anévrismes et aux dilatations par voie endoluminale. The present invention relates to a tool for fitting a self-expanding stent for a human or animal tubular organ. It applies in particular to the treatment of aneurysms and dilations by the endoluminal route.
Les endoprothèses autoexpansibles sont généralement constituées d'un simple treillis métallique autoexpansible. Après une dilatation transluminale, elles sont introduites, au moyen d'une sonde, par voie endoluminale, puis libérées. Self-expanding stents generally consist of a simple self-expanding wire mesh. After a transluminal dilation, they are introduced, by means of a probe, by the endoluminal route, then released.
L'invention a pour objet un outil de mise en place d'une endoprothèse autoexpansible telle que définie ci-dessus. Cet outil comprend
- un conduit-guide pourvu à son extrémité distale d'une tulipe sécable de logement de l'endoprothèse à l'état contracté; et
- des moyens pour découper la tulipe en plusieurs pétales.The invention relates to a tool for fitting a self-expanding stent as defined above. This tool includes
- a guide duct provided at its distal end with a breakable tulip for housing the stent in the contracted state; and
- 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 wires for cutting the tulip connected to an actuating handle.

L'endoprothèse 1 représentée aux Figures 1 et 2 est constituée d'un treillis tubulaire 2 noyé dans un film 3. The endoprosthesis 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. Il peut être réalisé par tissage ou tricotage d'un fil, déploiement axial d'un tube, ou par toute autre technique appropriée. 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. Mesh 2 is made of biocompatible quality stainless steel. It can be produced by weaving or knitting a thread, axial deployment of a tube, or by any other suitable technique. I1 is plastically deformable, that is to say it has a first stable shape of small diameter, shown in Figure 1, in which the meshes form elongated diamonds parallel to its axis, and a second stable shape of diameter very enlarged and of shorter length, shown in Figure 2, in which the meshes form diamonds elongated 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. 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. Des matières appropriées sont un élastomère biocompatible, qui peut être un caoutchouc naturel ou synthétique, ou bien un polymère biocompatible tel qu'un polyuréthanne. The mesh 2 is entirely embedded in a film 3 of an extensible and liquid-tight material which fills the meshes. The extensibility of this material is sufficient for the film 3 to be able to follow the deformation of the mesh 2 from its contracted state to its expanded state without tearing or detachment, despite the deformation of the mesh of the mesh. Suitable materials are a biocompatible elastomer, which can be natural or synthetic rubber, or a biocompatible polymer such as a 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 techniques, after degreasing of the metal and its treatment with a primary adhesion 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. 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. One thus obtains, in the dilated state (Figure 2), a liquid-tight tubular section which can be used as a stent or "stent" after transluminal dilation. This stent does not traumatize the tissues and practically does not create turbulence in the blood flow, since the tissues and the blood are in contact with a practically smooth surface of 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. Due to its tightness, the endoprosthesis can be used to treat an aneurysm by the endoluminal route, by making it bridge the aneurysm, each of its ends applying radially against the interior wall of a healthy artery section adjacent to 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, illustrated in Figures 3 to 7, the mesh 2 of the stent 1A is self-expanding, which is obtained conventionally by using a stainless steel having spring properties.
Pour mettre en place l'endoprothèse lA, on la comprime radialement jusqu a sa configuration de la
Figure 1, qui n'est pas stable, et on l'introduit dans la tulipe d'extrémité 4 d'un outil 5 représenté sur les
Figures 3 à 5.To set up the stent lA, it is compressed radially until its configuration of the
Figure 1, which is not stable, and is introduced into the end tulip 4 of a tool 5 shown in the
Figures 3 to 5.
L'extrémité distale de la tulipe 4 est ouverte et présente trois échancrures 6 à 120C les unes des autres. 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. The distal end of the tulip 4 is open and has three notches 6 at 120C from each other. Its proximal end forms an internal shoulder 7 from which a guide duct 8 starts. In the plane of each notch 6, a channel 9 formed in the wall thickness of the duct 8 opens out to the outside by radial orifices 10, 11, on the one hand near the shoulder 7, on the other hand near the proximal end of the duct 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. One can also provide in the wall thickness of the conduit 8, as shown, longitudinal channels 12, 13 for injecting fluids, which leave from the proximal end of this conduit and open into the interior lumen of the conduit 8 near 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). 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. In each of the three aforementioned planes, a flexible wire 14 passes through the notch 6. An inner strand 15 of this wire runs along the inner wall of the tulip 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 joins an actuating handle 17 (Figure 3). An outer strand 18 of the wire 14 runs along the outer 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 six strands of wire, and the three strands Interiors 15 are pressed against the interior wall of the tulip by the tendency of the stent 1A to expand.
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 endoprosthesis, after a transluminal dilation or to treat an aneurysm, the tool 5 is threaded on a guide, introduced through the skin and led by the endoluminal route 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. La tulipe libère donc progressivement l'endoprothèse, laquelle se dilate d'elle-même, comme illustré sur la
Figure 6. Lorsque la tulipe est entièrement ouverte, on retire l'outil par traction sur le conduit 8.This puts the three wires 15 in tension, and these wires each cut the tulip 4 according to a generator. The tulip therefore gradually releases the stent, which expands by itself, as illustrated in the
Figure 6. When the tulip is fully open, the tool is removed by pulling on line 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. La stabilité du positionnement de l'endoprothèse est ainsi assurée. In the dilated state (FIG. 7), it can be seen that the two ends of the endoprosthesis have flared themselves, which gives two advantageous effects on the one hand, the seal between the endoprosthesis and the artery is reinforced, and on the other hand, the ends 19 of the wires of the mesh 2 protrude slightly from the film 3 and constitute as many attachment points of the endoprosthesis in the artery. Stability of positioning of the stent is thus 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 can be used to form the mesh 2. For example, to produce a self-expanding stent, it is possible to use wire of a relatively rigid polymer with spring properties such as polytetrafluoroethylene (PTFE), made radio-opaque.
