Latchless surgical clip
First Claim
Patent Images
1. A latchless surgical clip for application to body tissue, which comprises:
- a polymeric clip body possessing a pair of legs, opposed surfaces of which constitute tissue clamping surfaces in the tissue clamping configuration of the applied clip, and a hinge region possessing an elastic spring back property to which one end of each leg is attached, the other end of each leg being free, each leg being movable about the hinge region; and
,latchless tissue clamping means on the tissue clamping surface of at least one leg, the tissue clamping means of said at least one leg cooperating with the opposed tissue clamping surface in the tissue clamping configuration of the clip to impart a tissue clamping force to said tissue,wherein the latchless tissue clamping means comprises upper and lower staggered tooth-like projections on said at least one leg.

Abstract
A latchless surgical clip provides effective hemostasis while avoiding or minimizing the risk of injury to the tissue site to which the clip is applied. The clip includes a hinge region having an elastic spring back property so that the legs are spread apart to engage opposing sides of the tissue and then released to return to their tissue clamping (closed) position. A method for forming the latchless surgical clip and a fixture for use therein are also described.
