Abstract
A polymeric, surgical clip having first and second curved leg members joined at their proximal end by a hinge portion and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces. The clip includes a coating on its exterior which reduces the friction between the leg members and complementary locking mechanisms disposed at the distal end portions of the leg members, and stabilizes closing of the clip. The coating can be any coating, including a polymer coating such as one which includes polytetrafluoroethylene. The coating may be applied using a solvent such as HFC43-10.

18. A surgical ligating clip comprising:
-
a polymeric clip body having first and second leg members, each having respective proximal and distal end portions, the clip body having an exterior surface, a hinge means coupling the first and second leg members at their respective proximal end portions to enable the first and second leg members to move between an open position of the clip body and a closed position of the clip body, complementary locking means disposed on the distal end portions of the leg members to maintain the clip body in the closed position when moved to the closed position, and a coating layer on at least a portion of the exterior surface of the clip body. - View Dependent Claims (19, 20)
