Abstract

L'invention concerne la chirurgie vasculaire et porte sur une prothèse (endoprothèse) comprenant un anneau flexible (1) et un anneau élastique (2) fixés l'un à l'autre, l'anneau flexible (1) étant placé à l'intérieur de l'anneau élastique (2), et la cavité de ce dernier servant de siège à la source d'intervention thérapeutique. Le procédé de mise en place à distance d'une prothèse sur un organe tubulaire consiste à déformer la prothèse dans le sens radial, puis dans deux plans frontaux ; la déplacer selon le système de mise en place à distance et la fixer par rapport à une extrémité de travail du système ; introduire l'extrémité de travail du système dans le segment du vaisseau à remplacer et la fixer à ce segment ; retirer la fixation de la prothèse en relation avec l'extrémité de travail du système ; effectuer au moins une inosculation ; retirer la fixation de l'extrémité de travail du système en relation avec le segment du vaisseau à remplacer et l'extraire du vaisseau. Le système de mise en place à distance d'une prothèse sur un organe tubulaire comprend un dispositif de transport pourvu d'un guide tubulaire flexible (14) et un mécanisme de fixation de la prothèse en relation avec l'extrémité de travail du guide tubulaire (14), ainsi qu'un mécanisme de fixation du dispositif de transport précité en relation avec le segment du vaisseau à remplacer.
