Abstract

The invention provides a surgical clip for use in conjunction with a clip applier. The clip may be closed in a curved shape, has improved gripping capabilities, and maximizes the gripping surface relative to clip size. The clip preferably includes a longitudinal channel through the gripping surfaces of the clip legs, the channel having at least one sidewall inclined to form an undercut, such that the channel is wider at its floor than at its opening in the gripping surface. The clip further may have one leg longer than the other such that the clip may be closed in a curved shape with the legs parallel and the tips of the legs substantially even. The clip may also have one or more inverse arcuate portions on at least one of its legs to improve the tightness of clip closure.
