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.

Why it's free to use
- Filed May 22, 1990 and granted March 7, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 22, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 22, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
