1. A surgical apparatus comprising:

  • a first jaw including a plurality of retention slots;

    a second jaw including a plurality of grooves;

    a plurality of fasteners disposed in the plurality of retention slots, each fastener including first and second legs, wherein each groove is configured to direct the legs of the fastener towards each other resulting in a formed portion and an unformed portion in each leg, and wherein the formed portion of the first leg at least partially overlaps the unformed portion of the second leg;

    a first driving mechanism configured to urge the fastener towards the groove and including a first sled and an ejector, and wherein distal longitudinal movement of the first sled through the first jaw causes movement of the ejector towards the second jaw and urges the fastener towards the groove; and

    a second driving mechanism including a second sled and a movable member, wherein distal longitudinal movement of the second sled through the first jaw causes movement of the movable member towards the second jaw, the moveable member of the second driving mechanism operable to deform a backspan of the fastener when a distance between the first and second jaws is less than a predetermined value.
