Abstract:
PCT No. PCT/US93/10054 Sec. 371 Date Jun. 4, 1996 Sec. 102(e) Date Jun. 4, 1996 PCT Filed Oct. 20, 1993 PCT Pub. No. WO95/10983 PCT Pub. Date Apr. 27, 1995A process for manufacturing an aneurysm clip (10) having a coil spring (22), a first arm (26) ending in a first clamping jaw, and a second arm (34) ending in a second clamping jaw (40). The method includes: (a) providing a cylindrical starting rod (1) of titanium or titanium alloy; (b) cold drawing the rod to reduce its diameter and increase its strength; (c) cutting the rod to form a single resilient member (12); (d) winding the member about a mandrel to form the coil spring while incorporating the deflection of the arms into the clamping force of the clip; (e) shaping the member into two end sections (16) forming the clamping jaws and two connecting sections (18) forming connecting elements for the jaws; (f) coining the two end sections of the member a temperature between 900 and 1000 degrees F.; and (g) bending the clamping jaws into a position assuring that the clamping jaws are parallel when clamped onto tissue (70).
