Surgical hemostatic clips
First Claim
1. A hemostatic clip comprising first and second legs each leg having a tissue contacting surface and an applier contacting surface and each leg having a distal end and joined at their proximal ends in a hinge region, said first leg including a longitudinal projection extending along at least a substantial length of said first leg for engaging a longitudinal groove formed in said second leg and extending along at least a substantial length of said second leg, whereby engagement of said longitudinal projection and said longitudinal groove affords substantially gapless closure of said clip, and wherein said longitudinal groove and said longitudinal projection are formed on the tissue contacting surface of said legs, said applier contacting surfaces of said legs formed wherein the dimension between the applier contacting surface and tissue contacting surface of said second leg is greater than the dimension between the applier contacting surface and tissue contacting surface of said first leg.

Abstract
A surgical hemostatic clip which afford substantially gapless closure includes a longitudinal groove formed in the tissue-contacting surface of one leg, and an opposing longitudinal tongue formed on the tissue-contacting surface of the other leg. In a preferred embodiment the longitudinal tongue and groove do not extend to the distal ends of the legs so as to provide distal flat surfaces on the tissue-contacting distal leg ends. Transverse grooves may be formed across the tongue and in intersection with the longitudinal groove to enhance the tissue-gripping characteristics of the hemostatic clip.
