Non-metallic, bio-compatible hemostatic clips with interlocking latch means
First Claim
1. A hemostatic clip comprising first and second leg members, each leg member having an elongated vessel clamping inner face in opposition to a vessel clamping inner face of the other leg member, said first leg member terminating at its distal end in a bend forming a hook member extending from said vessel clamping inner face, said second leg member terminating at its distal end in a complementary bend forming a complementary hook member for engagement by said hook member of said first leg member, resilient hinge means joining said first and second leg members at their proximal end, the hook member of the first leg member extending towards said resilient hinge means and the hook member of said second leg member extending at an angle to said resilient hinge means, said first and second leg members being rotatable about said hinge means from an open position wherein said legs diverge from one another to a closed position wherein said legs are substantially parallel, said hook members being disposed complementary with regard to one another to interlock the legs in the closed position and maintain said legs substantially parallel and to prevent lateral movement between the vessel clamping inner faces of the leg members when the clip is in the closed position.

Abstract
Sterile, non-metallic bio-compatible hemostatic clips of absorbable and non-absorbable materials comprising two leg members joined with a resilient hinge. The distal ends of said leg members include latch means to lock the clip in a closed position. Each leg member has a vessel clamping inner face and the latch means includes means for preventing relative lateral movement between the vessel clamping inner faces when the clip is in a closed position.
