Abstract
Description
La présente invention a trait à une endoprothèse aortoiliaque pour le traitement, par exemple, des anévrismes aortiques ou aorto-iliaques sous-rénaux. The present invention relates to an aortoiliac stent for the treatment, for example, of aortic or aortoiliac aneurysms.
A ce jour, les traitements des anévrismes aortiques ou aorto-iliaques sous-rénaux sont réalisés soit par voie chirurcale, soit par voie endoluminale. To date, the treatment of aortic or aortoiliac aneurysms under renal is carried out either by surgical way, or by endoluminal way.
Dans le premier cas, c'est-à-dire par voie chirurgicale, le traitement est assez délicat et nécessite des anesthésies assez longues. De manière succinte, on procède à une intervention au niveau de l'anévrisme pour mettre en place une prothèse aortique. In the first case, that is to say by the surgical route, the treatment is fairly delicate and requires fairly long anesthesia. Briefly, we proceed to an aneurysm intervention to put in place an aortic prosthesis.
Il faut tout d'abord disposer des pinces supérieure et inférieure de part et d'autre de l'anévrisme. Ensuite, on coupe l'artère au niveau de l'anévrisme pour permettre la mise en place de la prothèse qui est suturée à chaque extrémité de l'artère. Enfin, la prothèse est enveloppée dans l'épaisseur de l'artère pour l'isoler des éléments vivants voisins. La circulation sanguine est ensuite réalisée par le retrait des pinces et le chirurgien procède à la fermeture de tous les éléments vivants annexes. On note que cette opération est très délicate pour les personnes agées et l'on rencontre à long terme des ennuis pariétaux, c'est-à-dire des risques d'éventration. First you need the upper and lower clamps on either side of the aneurysm. Then, the artery is cut at the aneurysm to allow the placement of the prosthesis which is sutured at each end of the artery. Finally, the prosthesis is wrapped in the thickness of the artery to isolate it from neighboring living elements. The blood circulation is then carried out by removing the forceps and the surgeon proceeds to close all of the living ancillary elements. It is noted that this operation is very delicate for the elderly and there are long-term parietal problems, that is to say risks of eventration.
Dans le second cas, le traitement est réalisé sans intervention chirurgicale. En effet, les endoprothèses sont introduites à distance de la zone pathologique et positionnées à l'aide d'une installation radiologique. Le principe est d'amener la prothèse ou l'endoprothèse sur les lieux à partir d'un accès fémoral ou iliaque externe, c'est-à-dire superficiel et peu traumatisant. In the second case, the treatment is carried out without surgical intervention. Indeed, the stents are introduced at a distance from the pathological area and positioned using a radiological installation. The principle is to bring the prosthesis or endoprosthesis to the site from an external femoral or iliac access, that is to say superficial and not very traumatic.
La présente invention a pour but de perfectionner les traitements par voie endoluminale afin de faciliter la pose des endoprothèses au niveau d'un anévrisme aortique ou aorto-biiliaque. The object of the present invention is to improve the endoluminal treatments in order to facilitate the placement of stents at the level of an aortic or aorto-biiliac aneurysm.
L'endoprothèse aorto-iliaque suivant la présente invention comprend au moins un tube souple à profil conique susceptible de se déformer élastiquement dans toutes ses directions et dont chaque extrémité est solidaire d'un manchon déformable réalisé en une matière métallique bio-compatible à mémoire de forme muni de moyens d'accrochage pour la retenue de l'endoprothèse. The aortoiliac endoprosthesis according to the present invention comprises at least one flexible tube with conical profile capable of deforming elastically in all its directions and each end of which is integral with a deformable sleeve made of a bio-compatible metallic material with memory of form provided with attachment means for retaining the stent.
En outre, l'endoprothèse aorto-iliaque comprend deux tubes souples à profil conique susceptibles de se déformer élastiquement dans toutes leurs directions et dont les extrémités de chaque tube sont solidaires d'un manchon grillagé déformable qui est réalisé en une matière métallique bio-compatible à mémoire de forme muni de moyens d'accrochage, tandis que les extrémités de plus grand diamètre de chacun des tubes sont réunies par déformation des manchons grillagés de manière que la périphérie externe de chaque tube d'une part épouse parfaitement la paroi interne de l'aorte abdominale et d'autre part est en appui contre la périphérie externe de l'autre tube pour assurer une parfaite étanchéité de l'endoprothèse. In addition, the aortoiliac endoprosthesis comprises two flexible tubes with a conical profile capable of deforming elastically in all their directions and the ends of each tube of which are integral with a deformable mesh sleeve which is made of a bio-compatible metallic material. shape memory provided with hooking means, while the ends of larger diameter of each of the tubes are joined by deformation of the mesh sleeves so that the outer periphery of each tube on the one hand perfectly matches the inner wall of the 'abdominal aorta and on the other is in abutment against the outer periphery of the other tube to ensure a perfect seal of the stent.

- Figures 5 et 6 sont des coupes à plus grande échelle suivant V-V de figure 3 et VI-VI de figure 4 de l'aorte abdominale au niveau de la fixation supérieure de l'endopro- thèse aorto-iliaque. - Figures 5 and 6 are sections on a larger scale along V-V of Figure 3 and VI-VI of Figure 4 of the abdominal aorta at the level of the upper fixation of the aorto-iliac endoprosthesis.
On a représenté schématiquement en figure 1 une aorte abdominale 1 se séparant en une première artère la dite "artère iliaque primitive gauche" et en une seconde artère lb dite "artère iliaque primitive droite". L'aorte abdominale 1 comporte au-dessus des artères iliaques la et lb une artère mésentérique inférieure ic, une artère rénale gauche id et une artère rénale droite le. L'artère iliaque primitive gauche la se prolonge par une artère iliaque externe gauche lq et par une artère iliaque interne gauche 11. Egalement, l'artère iliaque primitive droite lb se prolonge par une artère iliaque externe droite 1h et par une artère iliaque interne droite li. There is shown schematically in FIG. 1 an abdominal aorta 1 dividing into a first artery called the "left primary iliac artery" and into a second artery 1b called "right primary iliac artery". The abdominal aorta 1 has above the iliac arteries la and lb a lower mesenteric artery ic, a left renal artery id and a right renal artery le. The left primary iliac artery la is extended by a left external iliac artery lq and by a left internal iliac artery 11. Also, the right primary iliac artery lb is extended by a right external iliac artery 1h and by a right internal iliac artery li.
On a montré en traits mixtes un exemple de profil d'anévrisme if de l'aorte abdominale 1 qui se situe en dessous des artères rénales ld et le et qui peut se prolonger sur les artères iliaques primitives la et lb. We have shown in dashed lines an example of an aneurysm profile if of the abdominal aorta 1 which is located below the renal arteries ld and le and which can extend over the primary iliac arteries la and lb.
En figure 2, on a représenté une endoprothèse aortoiliaque 2 comprenant deux tubes 2a semblables et de même configuration. Chaque tube 2a est réalisé dans une matière biocompatible pour éviter tout rejet de la part des organes vivants voisins. Les tubes 2a sont prévus suffisamment souples et déformables élastiquement suivant toutes leurs directions. In Figure 2, there is shown an aortoiliac endoprosthesis 2 comprising two similar tubes 2a and of the same configuration. Each tube 2a is made of a biocompatible material to avoid any rejection from neighboring living organs. The tubes 2a are provided with sufficient flexibility and elastically deformable in all their directions.
La matière préférablement utilisée pour la fabrication des tubes peut être par exemple du type dénommé sous l'appellation "DACRON". The material preferably used for the manufacture of the tubes may for example be of the type called under the name "DACRON".
On constate que les tubes 2a sont prévus d'une longueur adéquate pour répondre aux traitements des anévrismes de l'aorte abdominale 1 situés entre les artères rénales id, le et les artères iliaques primitives la, lb. It can be seen that the tubes 2a are provided with an adequate length to respond to the treatment of aneurysms of the abdominal aorta 1 situated between the renal arteries id, le and the primitive iliac arteries la, lb.
Pour cela, chaque tube 2a présente un profil conique afin que les extrémités supérieures 2b, soient d'un diamètre plus important que celui des extrémités inférieures. For this, each tube 2a has a conical profile so that the upper ends 2b, are of a larger diameter than that of the lower ends.
Les extrémités supérieures 2b coopèrent respectivement avec un manchon grillagé 3. Chaque extrémité inférieure 2c est reliée à un manchon grillagé 4 de diamètre inférieur à celui des manchons 3. The upper ends 2b cooperate respectively with a mesh sleeve 3. Each lower end 2c is connected to a mesh sleeve 4 with a diameter smaller than that of the sleeves 3.
Les manchons 3, 4 sont prévus dans un alliage métallique à mémoire de forme. Chaque manchon 3, 4 comporte, par exemple, des petits crochets 5, dirigés en direction de l'extérieur et régulièrement répartis sur le pourtour de chaque manchon. Les extrémités supérieure 2b et inférieure 2c de chaque tube 2a recouvrent en totalité les manchons correspondants 3, 4 ne laissant passer que les crochets 5 pour la retenue de l'endoprothèse 2 dans la paroi interne de l'aorte abdominale 1 ou de l'artère iliaque primitive la, lb. Les crochets 5 sont solidaires des extrémités libres de chaque manchon 3, 4, c'est-à-dire celles dépassant à l'extrémité de chaque tube 2a. The sleeves 3, 4 are provided in a metal alloy with shape memory. Each sleeve 3, 4 has, for example, small hooks 5, directed towards the outside and regularly distributed around the periphery of each sleeve. The upper 2b and lower 2c ends of each tube 2a completely cover the corresponding sleeves 3, 4 allowing only the hooks 5 to retain the stent 2 in the internal wall of the abdominal aorta 1 or the artery primitive iliac la, lb. The hooks 5 are integral with the free ends of each sleeve 3, 4, that is to say those protruding at the end of each tube 2a.
L'endoprothèse 2 est introduite à l'intérieur de l'aorte abdominale 1 par voie endoluminale, c'est-à-dire au moyen d'un dispositif à poches particulier décrit dans une demande de brevet appartenant au Demandeur. The endoprosthesis 2 is inserted inside the abdominal aorta 1 by the endoluminal route, that is to say by means of a particular bag device described in a patent application belonging to the Applicant.
En effet, chaque tube 2a, solidaire de ses manchons 3, 4 est introduit par un dispositif à poches dans respectivement l'artère iliaque externe gauche la et droite 1h ou la fémorale commune correspondante jusqu'à ce que son extrémité supérieure 2b solidaire du manchon 3 soit placée en dessous des artères rénales ld, le, tandis que son extrémité inférieure 2c munie de son manchon 4 coopère, suivant le cas opératoire, avec l'artère iliaque primitive la, lb ou avec l'artère iliaque externe la, 1h (figure 3). Indeed, each tube 2a, integral with its sleeves 3, 4 is introduced by a bag device into the left external iliac artery respectively the 1a and 1h or the corresponding common femoral until its upper end 2b secured to the sleeve 3 is placed below the renal arteries ld, le, while its lower end 2c provided with its sleeve 4 cooperates, depending on the operating case, with the primary iliac artery la, lb or with the external iliac artery la, 1h ( figure 3).
Les extrémités supérieures 2b sont déformées au moyen des dispositifs à poches particuliers de manière que les manchons grillagés 3 viennent plaquer chaque tube 2a contre la paroi interne de l'aorte abdominale 1. On remarque que les crochets 5 de chaque manchon 3 pénètrent dans la paroi interne de l'aorte abdominale 1 pour améliorer l'ancrage de l'endoprothèse 2. The upper ends 2b are deformed by means of special pocket devices so that the mesh sleeves 3 press each tube 2a against the internal wall of the abdominal aorta 1. It is noted that the hooks 5 of each sleeve 3 penetrate the wall internal of the abdominal aorta 1 to improve the anchoring of the stent 2.
De même, les extrémités inférieures 2c sont déformées au moyen des dispositifs à poches particuliers de manière que les manchons grillagés 4 de chaque tube 2a viennent plaquer contre la paroi interne de l'artère iliaque primitive la, lb ou contre la paroi interne de l'artère iliaque externe la, lh. Likewise, the lower ends 2c are deformed by means of particular pocket devices so that the mesh sleeves 4 of each tube 2a press against the internal wall of the primary iliac artery 1a, 1b or against the internal wall of the external iliac artery la, lh.
Il suffit ensuite de retirer les dispositifs à poches particuliers pour permettre à la circulation sanguine de traverser l'endoprothèse 2 et de soulager définitivement l'aorte abdominale 1 pour empêcher toute rupture de l'anévrisme if. It is then sufficient to remove the devices with particular bags to allow the blood circulation to pass through the stent 2 and to permanently relieve the abdominal aorta 1 to prevent any rupture of the aneurysm if.
On remarque, après déformation des extrémités supérieures 2b des tubes 2a et des manchons 3 que la périphérie externe de chaque tube 2a d'une part épouse parfaitement la paroi interne de l'aorte abdominale 1, et d'autre part est en appui contre la périphérie externe de l'autre tube pour assurer une étanchéité entre lesdits tubes 2a de l'endoprothèse 2 (figure 5). It is noted, after deformation of the upper ends 2b of the tubes 2a and of the sleeves 3 that the external periphery of each tube 2a on the one hand perfectly matches the internal wall of the abdominal aorta 1, and on the other hand is pressed against the outer periphery of the other tube to ensure a seal between said tubes 2a of the stent 2 (Figure 5).
Pour cela, il est prévu que le diamètre des manchons 3 soit suffisant pour permettre leur déformation simultanée pour obtenir la configuration de figure 5. For this, provision is made for the diameter of the sleeves 3 to be sufficient to allow their simultaneous deformation to obtain the configuration of FIG. 5.
On a représenté en figures 4 et 6 une variante de l'endo prothèse 2 suivant la présente invention dont l'extrémité supérieure 2b de chaque tube 2a est solidaire d'un manchon 3 ayant la même configuration que ceux décrits préalablement. On remarque que chaque manchon 3 est dans ce cas partiellement engagé à l'intérieur du tube 2a correspondant. There is shown in Figures 4 and 6 a variant of the endo prosthesis 2 according to the present invention, the upper end 2b of each tube 2a is secured to a sleeve 3 having the same configuration as those described above. Note that each sleeve 3 is in this case partially engaged inside the corresponding tube 2a.
En effet, cette solution est prévue lorsque l'anévrisme if remonte à proximité des artères rénales id et le, supprimant ainsi une partie de l'aorte abdominale 1 pour la fixation de l'endoprothèse 2. Dans ce cas, les manchons 3 doivent venir se fixer au-dessus des artères rénales ld et le sans que l'extrémité supérieure 2b de chaque tube 2a vienne les obstruer. Indeed, this solution is provided when the aneurysm if goes back near the renal arteries id and the, thus removing part of the abdominal aorta 1 for fixing the stent 2. In this case, the sleeves 3 must come fix above the renal arteries 1d and the without the upper end 2b of each tube 2a obstructing them.
Ainsi, les manchons 3 sont déformés de la même manière que précédemment, mais les crochets 5 viennent se fixer dans la paroi interne de l'aorte abdominale 1 et au-dessus des artères rénales ld et le, tandis que les extrémités supérieures 2b de chaque tube 2a se trouvent en dessous des artères rénales id et le. La configuration des manchons 3 permet l'écoulement du flux sanguin dans les artères rénales ld et le et ceci sans les obstruer. Thus, the sleeves 3 are deformed in the same manner as above, but the hooks 5 are fixed in the internal wall of the abdominal aorta 1 and above the renal arteries ld and le, while the upper ends 2b of each tube 2a are found below the renal arteries id and the. The configuration of the sleeves 3 allows the flow of blood flow in the renal arteries ld and the and this without obstructing them.
De même, les manchons 4 de chaque tube 2a adaptés à l'extrémité inférieure 2c peuvent n'être engagés que partiellement afin de pouvoir s'ancrer dans l'artère iliaque externe la, 1h sans empêcher le passage du flux sanguin dans l'autre artère iliaque interne li, li. Similarly, the sleeves 4 of each tube 2a adapted to the lower end 2c may only be partially engaged in order to be able to anchor in the external iliac artery la, 1h without preventing the passage of blood flow in the other internal iliac artery li, li.
Chaque fil constituant le grillage des manchons 3 et 4 présente un état de surface adapté pour assurer un ancrage suffisant soit à l'intérieur de chaque tube 2a, soit à l'intérieur de chaque artère. Each wire constituting the mesh of the sleeves 3 and 4 has a surface condition suitable for ensuring sufficient anchoring either inside each tube 2a, or inside each artery.
Il va de soi que les tubes 2a de l'endoprothèse 2 peuvent se croiser sans influencer la méthode de fixation de ladite endoprothèse. It goes without saying that the tubes 2a of the stent 2 can cross without influencing the method of fixing said stent.
Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
