Abstract
Apparatus and method for applying a surgical staple which experiences some spring back following deformation. The invention enables the surgical staple to assume a rectangular shape with the tips thereof positioned together after the staple is closed. Specifically, the staple is deformed to overlap the tips so that release of deforming pressure results in tip-to-tip contact upon spring back. The invention addresses problems relating to skin being interposed between the spaced tips when a staple is closed. Also, as a result of the square-cornered rectangular shape of the closed staple, the problem of rotation of the staple after it is applied to the tissue is impeded. Preferably, the staple is heat recoverable having an open-shape memory configuration.
