Abstract
Abstract An apparatus for applying a tissue fastener for fastening soft tissue to bone includes elongated members, one of which holds a loading unit having a tissue fastener mounted therein, and another of which is moved to expel the tissue fastener from the loading unit and expand legs of the tissue fastener to secure it within a predrilled hole in bone. The tissue fastener is preferably a two piece fastener including a body portion with legs flexibly expandable by a setting pin. The loading unit engages both the body and the setting pin.
