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.
