Abstract

Une endoprothèse flexible comporte des caractéristiques permettant de minimiser son relâchement et de faciliter son ancrage dans la lumière d'un vaisseau. Sa conception est caractérisée par des courbures à angles vifs (8). Parmi les autres caractéristiques, on trouve une section transversale arrondie au niveau du composant fil métallique (1) ou prothèse, ainsi que la flexion des courbures angulaires (8) dans un plan transversal, ce qui accroît la rigidité et constitue un mécanisme d'ancrage. Des liens (3) alignés ou en zigzags, semi-rigides ou flexibles, permettent à la structure, qui peut être constituée d'anneaux reliés (20) ou d'un dispositif hélicoïdal, d'être plus flexible afin de s'adapter aux courbures du système vasculaire. L'invention concerne également les liens (3, qui comportent un système de verrouillage courbant le fil métallique (1) au moment où l'on donne à celui-ci une forme d'hélice en le combinant à un lien transversal (60) pourvu de boucles (96) qui bloquent la prothèse en position étendue.
