Abstract

A surgical staple is disclosed comprising an arcuate central region which can be flattened by a stapling tool. Straight legs extend obliquely upwardly from the central region to which are connected downwardly extending side portions. The side portions are curved substantially in the form of an arc of a circle having a center at the center for the central region. When the central region is flattened, the side portions move about an arc of a circle so that automatic puncture channels are produced. Tearing of tissue is thereby prevented.
