ABSTRACT:
A malleable, bioabsorbable polymeric staple includes a back span with two legs depending perpendicularly therefrom that are deformed along an arcuate path toward each other initially and then upwardly toward the back span such that end points on each leg extend through a gap formed between an underside of the back span and a bend in an opposite leg. A surgical staple-deforming anvil for deforming the staples has a staple-receiving face formed with a pair of guiding path depressions each having an entry end lying on a longitudinal axis parallel to the back span of the staple, and an exit end. The guiding paths are arcuately shaped and form a groove curving and crossing each other approximately at the longitudinal axis. Accordingly, the legs of a staple driven toward the anvil and received in the guiding paths are initially bent toward each other and then steered upwardly and along the horizontally curved path toward the gap formed between the back span and the bend in the opposite leg.
