ABSTRACT:
An instrument for stapling body tissue including a staple, a retainer, and a plunger. The staple is preformed in a closed state and is made of a body-compatible material. The staple material has a stress plateau such that the staple may be flexed to an open state without permanent deformation. The retainer stores the staple in the open state and the plunger ejects the staple from the retainer such that the staple returns itself to the preformed closed state in the body tissue.
