Abstract
Abstract A surgical staple of the type which is applied by being bent around an anvil in a surgical stapler has two spaced surfaces transverse to the longitudinal axis of the staple and located so that when the staple is bent around the anvil, the transverse surfaces cooperate with the anvil to prevent the staple from being pulled back into the stapler.
