Abstract
A hemostatic clip for surgical use is disclosed having grooves on the inner surfaces of the legs which form an asterisk type pattern upon closure, knee bends in each leg which are opposed by notches or grooves that enhance the ability of the legs to fully straighten upon closure, and distal flat surfaces on the ends of the clip legs to prevent scissoring and ensure hemostasis when the clip is closed.
