Non-metallic, bio-compatible hemostatic clips

Claim 1

A hemostatic clip of a relatively nonresilient and nondeformable polymeric material comprising a pair of leg members, said leg members having opposed vessel clamping surfaces, said leg members being attached or attachable at their proximal ends in a rotatable hinge portion, said hinge portion comprising a pin integral with and disposed at the proximal end of one of the leg member and a complementary hook or eye integral with and disposed at the proximal end of the other leg member, a protrusion adjacent said hook or eye member causing the leg members to diverge from one another to hold the clip in an open position, said pin being sized to fit within the hook or eye, said hook or eye contacting the periphery of the pin and being rotatable about a portion of the periphery of the pin to move said protrusion out of its original position to allow said leg member to be moved from an open position wherein the legs diverge from one another to a closed position wherein the legs are substantially parallel with the vessel clamping surfaces adjacent one another and locking means for maintaining the legs substantially parallel when the clip is in a closed position.
