Abstract:
1. A dynamic bioabsorbable staple for use with a wound in living human tissue having opposed sides, the staple comprising: a bioabsorbable staple body including a pair of staple arms operably joined at a shoulder portion by a backspan, each arm further including an elbow portion having an inwardly projecting cleat, the staple arms, the inwardly projecting cleats and the backspan defining an internal tissue capture zone; and each shoulder portion including an interior shoulder angle generally defined by the backspan and the staple arm, the shoulder portion constructed so that the interior shoulder angle is between 70°–100° in a first position at an insertion time, the interior shoulder angle transitioning to between 120°–180° in a second deformed position at a second time subsequent to the insertion time in response to lateral forces naturally exerted by the opposed sides of the wound and deformation of at least the shoulder portions of the bioabsorbable staple body caused by polymeric creep and adsorption of the bioabsorbable staple body in the living human tissue.
