Abstract

A surgical fastener applier having a handle and a fastener housing extending from the handle. The housing contains at least one anvil movable within the staple housing, the anvil has a proximal position and a distal position. When in the distal position a distal end of the anvil extends distal to the distal end of the staple housing. The housing contains a plurality of surgical fasteners each of which in the shape of a loop. At least one of the fasteners is placed around a portion of the anvil when in the distal position. The applier has a first mechanism for moving the anvil distally after a fastener has been deployed, and a second mechanism for moving the anvil distally after a fastener has been deployed. The second means is independent of the first means.
