Description

Dispositif implantable comportant une prothèse et des moyens de fixation initialement liés à la prothèse Implantable device comprising a prosthesis and fixing means initially linked to the prosthesis
La présente invention concerne un dispositif implantable comportant une prothèse comportant un corps tubulaire muni à une extrémité d'une collerette de fixation, adaptée pour l'anastomose de la prothèse sur un conduit tubulaire muni d'une ouverture. Des prothèses de ce type sont utilisées couramment pour le remplacement d'un tronçon d'une artère ou d'une veine.The present invention relates to an implantable device comprising a prosthesis comprising a tubular body provided at one end with a fixing flange, suitable for the anastomosis of the prosthesis on a tubular conduit provided with an opening. Prostheses of this type are commonly used to replace a section of an artery or a vein.
Le brevet US 5 893 886 décrit une telle prothèse. La prothèse comprend un corps muni d'une collerette annulaire à une extrémité. Cette collerette est formée de deux couronnes annulaires coaxiales. Une première cou- ronne annulaire est liée au corps tubulaire depuis sa périphérie externe. Une seconde couronne annulaire est solidaire du bord extérieur de la première couronne et s'étend depuis ce bord extérieur autour du corps tubulaire de la prothèse. Le corps tubulaire s'étend au travers de l'orifice défini par la seconde couronne annulaire. La seconde couronne annulaire permet la liaison de la prothèse au vaisseau.US Patent 5,893,886 describes such a prosthesis. The prosthesis comprises a body provided with an annular collar at one end. This collar is formed by two coaxial annular rings. A first annular crown is linked to the tubular body from its external periphery. A second annular ring is integral with the outside edge of the first ring and extends from this outside edge around the tubular body of the prosthesis. The tubular body extends through the orifice defined by the second annular ring. The second annular crown allows the connection of the prosthesis to the vessel.
Pour la mise en place d'une telle prothèse, le chirurgien pratique une incision dans la paroi d'un vaisseau et glisse la collerette de la prothèse dans l'ouverture ainsi créée. La prothèse est ensuite fixée au vaisseau par des clips ou des agrafes, déformables plastiquement ou élastiquement, qui mettent en prise la seconde couronne annulaire et la paroi du vaisseau. Des premiers clips connus sont formés d'une pince en forme de V dont les mors sont lisses. Des seconds clips sont de structure identique et comportent en outre des crochets sur les faces en regard des mors. Ces clips sont, rapportés grâce à un outil approprié tel qu'une pince. Toutefois, la mise en place de ces clips est difficile. En effet, les clips dépourvus de crochets ont tendance à glisser une fois posés. Les clips munis de crochets, quant à eux, s'accrochent aux tissus pendant la mise en place et se détachent de la pince du chirurgien pendant la pose.For the establishment of such a prosthesis, the surgeon makes an incision in the wall of a vessel and slides the collar of the prosthesis into the opening thus created. The prosthesis is then attached to the vessel by clips or clips, plastically or elastically deformable, which engage the second annular crown and the vessel wall. The first known clips are formed of a V-shaped clamp whose jaws are smooth. Second clips are of identical structure and also have hooks on the facing faces of the jaws. These clips are attached using a suitable tool such as pliers. However, the installation of these clips is difficult. In fact, clips without hooks tend to slide once installed. The clips with hooks, on the other hand, hang on to the tissues during placement and detach from the surgeon's forceps during placement.
L'invention a pour but de permettre l'implantation d'une prothèse vas- culaire de façon aisée, rapide et fiable. A cet effet, l'invention a pour objet un dispositif implantable comportant une prothèse à collerette comprenant un corps tubulaire muni à une extrémité d'une collerette de fixation adaptée pour l'anastomose de la prothèse sur un conduit tubulaire muni d'une ouverture, caractérisé en ce qu'il com- porte au moins une pince de liaison, chaque pince comportant un premier mors fixé à ladite collerette, et un second mors solidaire du premier mors et déplaçable par rapport au premier mors entre une position de mise en place de la prothèse dans laquelle les deux mors sont écartés et une position de liaison dans laquelle les deux mors sont maintenus rapprochés définissant entre eux un espace de pincement.The object of the invention is to allow the implantation of a vascular prosthesis in an easy, rapid and reliable manner. To this end, the subject of the invention is an implantable device comprising a flange prosthesis comprising a tubular body provided at one end with a fixing flange suitable for the anastomosis of the prosthesis on a tubular conduit provided with an opening, characterized in that it comprises at least one connecting clamp, each clamp comprising a first jaw fixed to said flange, and a second jaw integral with the first jaw and movable relative to the first jaw between a position for placing the prosthesis in which the two jaws are separated and a connecting position in which the two jaws are kept close together defining between them a nip space.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins, sur lesquels : - la figure 1 est une vue en coupe transversale d'un premier mode de réalisation d'une prothèse selon l'invention ;The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the drawings, in which: - Figure 1 is a cross-sectional view of a first mode of production of a prosthesis according to the invention;
- la figure 2 est une vue en perspective d'un moyen de fixation d'une prothèse selon l'invention, pris isolément ; - la figure 3 est une vue en coupe transversale d'une prothèse, selon le premier mode de réalisation de l'invention, en cours d'implantation; et- Figure 2 is a perspective view of a means of fixing a prosthesis according to the invention, taken in isolation; - Figure 3 is a cross-sectional view of a prosthesis, according to the first embodiment of the invention, during implantation; and
- la figure 4 est une vue en coupe transversale d'un deuxième mode de réalisation d'une prothèse selon l'invention. Sur la figure 1 est représenté un dispositif implantable 10 comportant une prothèse à collerette 11 et des moyens 12 de fixation initialement soli- daires de la prothèse.- Figure 4 is a cross-sectional view of a second embodiment of a prosthesis according to the invention. In FIG. 1 is shown an implantable device 10 comprising a flange prosthesis 11 and means 12 for initially fixing the prosthesis.
La prothèse 11 est réalisée en un matériau tissé ou tricoté. Elle comporte un corps tubulaire 13 souple et une collerette de fixation 14 disposée à une extrémité du corps. Le corps tubulaire 13 est constitué d'un conduit tubulaire annelé, c'est-à-dire présentant sur l'essentiel de sa longueur un déformation permanente en hélice, également appelée cosselage.The prosthesis 11 is made of a woven or knitted material. It comprises a flexible tubular body 13 and a fixing flange 14 disposed at one end of the body. The tubular body 13 consists of a corrugated tubular conduit, that is to say having over most of its length a permanent deformation in a helix, also known as a shell.
Deux couronnes annulaires superposées 16, 18 forment la collerette de fixation 14. Une première couronne annulaire 16 prolonge le corps tubu- laire 13 au niveau de son extrémité de raccordement avec la collerette 14, ladite couronne 16 est liée au corps tubulaire 13 selon sa périphérie intérieure. Une seconde couronne annulaire 18 prolonge la première couronne 16. Cette seconde couronne 18 est sensiblement appliquée sur la face de la première couronne 16. La seconde couronne 18 est liée à la première cou- ronne selon leur périphérie extérieure commune. La seconde couronne 18 entoure ainsi l'extrémité du corps tubulaire 13.Two superimposed annular rings 16, 18 form the fixing flange 14. A first annular ring 16 extends the tubular body 13 at its connection end with the flange 14, said ring 16 is linked to the tubular body 13 along its periphery interior. A second annular ring 18 extends the first ring 16. This second ring 18 is applied substantially to the face of the first ring 16. The second ring 18 is linked to the first ring along their common external periphery. The second ring 18 thus surrounds the end of the tubular body 13.
Une pluralité d'orifices 19 est pratiquée dans la seconde couronne annulaire 18.A plurality of holes 19 is made in the second annular ring 18.
Les moyens de fixation 12 comportent un ensemble de pinces 20, chacune fixée à la collerette 14. Les pinces 20 sont réalisées en un matériau implantable tel qu'un polymère.The fixing means 12 comprise a set of clips 20, each fixed to the flange 14. The clips 20 are made of an implantable material such as a polymer.
Chaque pince 20 présente un premier mors 21, solidarisé à la seconde couronne annulaire 18 suivant sa surface en regard de la première couronne 16 par couture. A cet effet et comme on peut le voir sur la figure 2, le premier mors 21 présente, à sa périphérie, des trous 22 de fixation au travers desquels des fils de solidarisation sont engagés pour assurer la retenue de chaque pince par couture contre la seconde couronne 18. En variante, le premier mors 21 présente des zones de collage 24, réalisées par exemple en polymère thermofusible. Ainsi, le premier mors 21 est thermosoudé à la seconde couronne 18.Each clamp 20 has a first jaw 21, secured to the second annular ring 18 along its surface facing the first ring 16 by sewing. To this end and as can be seen in FIG. 2, the first jaw 21 has, at its periphery, fixing holes 22 through which connection wires are engaged to ensure the retention of each clamp by sewing against the second crown 18. As a variant, the first jaw 21 has bonding zones 24, produced for example from hot-melt polymer. Thus, the first jaw 21 is heat sealed to the second ring 18.
Le premier mors 21 présente un orifice 25 à une de ses extrémités. Cet orifice 25 est aligné avec un orifice 19 pratiqué dans la seconde couronne 18 de la collerette.The first jaw 21 has an orifice 25 at one of its ends. This orifice 25 is aligned with an orifice 19 formed in the second ring 18 of the collar.
Les pinces 20 comportent en outre chacune un second mors 26 articulé par rapport au premier mors 21 par l'intermédiaire d'une zone de charnière 28. Ainsi le second mors est déplaçable entre une position de mise en place, illustrée sur la partie gauche de la figure 3 et une position de fixation, illustrée sur la partie droite de la figure 3. Dans cette position de fixation, les deux mors 20, 21 définissent un espace de pincement. Le second mors 26 s'étend du côté opposé au premier mors 21 par rapport à la seconde couronne 18. La zone de charnière 28 est située au voisinage du bord intérieur de la seconde couronne, c'est-à-dire au voisinage du corps tubulaire 13. Ainsi, les pinces s'ouvrent à l'opposé du corps tubulaire 13.The clamps 20 each further comprise a second jaw 26 articulated with respect to the first jaw 21 by means of a hinge zone 28. Thus the second jaw is movable between a positioning position, illustrated on the left part of Figure 3 and a fixing position, illustrated on the right side of Figure 3. In this fixing position, the two jaws 20, 21 define a nip space. The second jaw 26 extends on the side opposite to the first jaw 21 relative to the second ring 18. The hinge zone 28 is located in the vicinity of the inner edge of the second ring, that is to say in the vicinity of the body. tubular 13. Thus, the clamps open opposite the tubular body 13.
Le second mors 26 comporte, sur son extrémité opposée à la zone de charnière 28, une broche crantée 32 adaptée pour s'engager par enclenchement élastique dans les orifices 19, 25 dans la position de fixation des moyens de fixation 12. La broche crantée 32 a une forme de tête de harpon, le diamètre extérieur des crans de la broche 32 étant supérieur au diamètre des orifices 19, 25 afin d'assurer le maintien de la pince en position de fixa- tion après engagement de la broche dans l'orifice 19.The second jaw 26 comprises, on its end opposite to the hinge zone 28, a notched pin 32 adapted to engage by elastic engagement in the orifices 19, 25 in the fixing position of the fixing means 12. The notched pin 32 has the shape of a harpoon head, the outside diameter of the notches of the spindle 32 being greater than the diameter of the orifices 19, 25 in order to ensure that the clamp is kept in the fixing position after engagement of the spindle in the orifice 19.
Pour la mise en place de la prothèse selon l'invention, et comme illus- tré sur la figure 3, le chirurgien pratique une incision dans une paroi 34 d'un vaisseau 36 et glisse la collerette 14 dans l'ouverture ainsi créée. Le second mors 26 des moyens de fixation est maintenu à l'extérieur du vaisseau 36. Le second mors 26 de chaque pince est ensuite rabattu, par exemple à l'aide d'une pince. La broche crantée 32 perfore la paroi 34 du vaisseau 36 et vient en prise avec le premier mors 21 , par enclenchement élastique au travers des orifices 19, 25. Ce procédé de fixation est plus rapide que celui consistant à placer des clips ou des agrafes initialement libres afin de fixer la collerette à la paroi du vaisseau. Qui plus est, les clips ne peuvent se détacher.For the fitting of the prosthesis according to the invention, and as illustrated in FIG. 3, the surgeon makes an incision in a wall 34 of a vessel 36 and slides the collar 14 into the opening thus created. The second jaw 26 of the fastening means is held outside the vessel 36. The second jaw 26 of each clamp is then folded down, for example using a clamp. The notched pin 32 perforates the wall 34 of the vessel 36 and engages the first jaw 21, by elastic engagement through the orifices 19, 25. This fixing process is faster than that of placing clips or staples initially free in order to fix the flange to the wall of the vessel. What's more, the clips cannot come off.
Sur la figure 4 est représenté un dispositif implantable 110 selon un second mode de réalisation de l'invention. Le dispositif implantable 110 comporte une prothèse à collerette 111 et des moyens de fixation 112. La prothèse 111 comporte un corps tubulaire 113 souple et une collerette de fixation 114 formée d'une unique couronne annulaire 116 reliée intérieurement à l'extrémité du corps 113. La couronne annulaire 116 comporte une pluralité d'orifices 119.In Figure 4 is shown an implantable device 110 according to a second embodiment of the invention. The implantable device 110 comprises a flange prosthesis 111 and fixing means 112. The prosthesis 111 comprises a flexible tubular body 113 and a fixing flange 114 formed by a single annular crown 116 connected internally to the end of the body 113. The annular crown 116 has a plurality of orifices 119.
Des pinces 20 identiques aux pinces 20 utilisées dans le premier mode de réalisation sont solidarisées au droit de chaque orifice avec leur orifice 30 aligné à l'orifice 119. Le premier mors 21 de chaque pince est solidaire de la surface de la couronne annulaire 116 disposée du côté du corps tubulaire 113. Les pinces 20 sont disposées sur la couronne 116 avec leur zone de charnière 28 du côté du corps tubulaire 113, ces pinces s'ouvrant à l'opposé du corps tubulaire 113. La mise en place et la fixation du second mode de réalisation de la prothèse s'effectuent comme exposé précédemment. Clamps 20 identical to the clamps 20 used in the first embodiment are secured to the right of each orifice with their orifice 30 aligned with the orifice 119. The first jaw 21 of each clamp is secured to the surface of the annular crown 116 disposed on the side of the tubular body 113. The clamps 20 are arranged on the crown 116 with their hinge zone 28 on the side of the tubular body 113, these clamps opening opposite the tubular body 113. The positioning and fixing of the second embodiment of the prosthesis are carried out as previously described.
