Non-metallic, bio-compatible hemostatic clips (two piece configured to lock tighter the larger the vessel being closed)
First Claim
1. A sterile, two-piece hemostatic clip for occluding vessels, said clip comprising a first piece having a spanning member with a vessel clamping surface, a leg member disposed at each end of said spanning member from the same side as said vessel clamping surface, each of said leg members comprising a U-shaped member with the inner facing surfaces of the legs of the U being beveled from their free ends towards the base of the U, said beveled surfaces terminating above the base of the U to form locking ears, said first piece being adapted to be placed on the vessel to be occluded by placing the associated U-shaped legs on opposite sides of the vessel and the vessel clamping inner surface in contact with said vessel and a straight second piece having a vessel clamping surface, said second piece being sized and configured to extend between and fit within each of said U-shaped members and be held in place by said ears.

Abstract
A sterile, two-piece hemostatic clip for occluding vessels. The first piece has a vessel clamping surface and a pair of legs extending from that surface. The second piece has a vessel clamping surface and locks with the first piece so that the vessel clamping surfaces face each other. The clamping surfaces are configured such that the locking forces are increased the greater the stress placed on the vessel clamping surfaces.
