Title
(EN) DEVICE FOR PLACING AN ENDO-PROSTHESIS
(FR) DISPOSITIF SERVANT A METTRE EN PLACE UNE ENDOPROTHESE
Abstract
(EN) The present invention pertains to the field of medicine and may be used in intra-vascular surgery as well as in endoscopic surgery for placing stents in the biliary ducts, in the transurethral canal as well as in vessels after an angioplasty treatment. The device for placing an endo-prosthesis comprises a main catheter (1) in which an additional catheter (2) is provided. This device also includes an endo-prosthesis (6) in the shape of a hollow reticular body. The additional catheter (2) comprises a string (3) which is arranged inside a capillary catheter (5) and is provided with hooks (4) at the corresponding end. The pleating of the endo-prosthesis (6) hollow and reticular body is made from one thread and its ends are made in the shape of loops. The number of loops at each end is at least equal to four, wherein said loops are made of a material with resilient properties. The material with resilient properties may consist of nitinol and include the following components: from 54.99 to 56 wt.% of nickel, from 45 to 43.8 wt.% of titanium and from 0.01 to 0.2 wt.% of palladium. The material exhibiting resilient properties may also consist of stainless steel.
(FR) Cette invention se rapporte au domaine de la médecine et peut être utilisée en chirurgie intravasculaire ainsi qu'en chirurgie endoscopique afin de placer des extenseurs dans les canaux biliaires, dans le canal transurétral ainsi que dans des vaisseaux après une angioplastie. Ce dispositif de mise en place d'endo-prothèse comprend un cathéter principal (1) à l'intérieur duquel se trouve un cathéter supplémentaire (2). Ce dispositif comprend également une endo-prothèse (6) qui se présente sous forme d'un corps creux réticulé. Le cathéter supplémentaire (2) renferme un filin (3) qui est disposé dans un cathéter capillaire (5) et qui comprend des crochets (4) à l'extrémité correspondante. Le tressage du corps creux et réticulé de l'endo-prothèse (6) est fait d'un seul fil et ses extrémités se présentent sous forme de boucles. Le nombre de boucles à chaque extrémité est au moins égal à quatre, lesquelles boucles sont faites d'un matériau ayant des propriétés élastiques. Le matériau ayant des propriétés élastiques peut consister en du nitinol qui comprend les composants suivants: de 54,99 à 56 % en poids de nickel, de 45 à 43,8 % en poids de titane et de 0,01 à 0,2 % en poids de palladium. Ce matériau possédant des propriétés élastiques peut également se composer d'acier inoxydable.
