Abstract
Procédé de fabrication d'un clip anévrysmal (10) muni d'un ressort hélicoïdal (22), d'un premier bras (26) se terminant par une première mâchoire de serrage, et d'un deuxième bras (34) se terminant par une deuxième mâchoire de serrage (40). Ce procédé consiste à: (a) prendre une tige de départ cylindrique (1) de titane ou d'alliage de titane; (b) tréfiler la tige afin d'en réduire le diamètre et d'en augmenter la résistance; (c) couper la tige pour former un élément élastique unique (12); (d) enrouler l'élément autour d'un mandrin pour former le ressort hélicoïdal tout en intégrant la déviation des bras dans la force de serrage du clip; (e) profiler l'élément sous forme de deux parties terminales (16) constituant les mâchoires de serrage et de deux parties intermédiaires (18) reliant les mâchoires; (f) forger par matriçage les deux parties terminales de l'élément à une température comprise entre 900 et 1000 ~F; et (g) recourber les parties mâchoires en une position permettant d'assurer qu'elles seront parallèles lorsqu'elles enserreront des tissus (70).
