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.

Claims

1. A surgical fastener applier comprising:

a. a handle;

b. a fastener housing extending from the handle;

c. said housing containing at least one anvil movable within said staple housing, said anvil having a proximal position and a distal position, wherein when in said distal position a distal end of said anvil extends distal to said distal end of said staple housing;

d. said housing containing a plurality of surgical fasteners each of which in the shape of a loop, wherein at least one of said plurality of surgical fasteners is placed around at least a portion of said at least one anvil when in said distal position;

e. a first means for moving said anvil distally after a fastener has been deployed;

f. a second means for moving said anvil distally after a fastener has been deployed, said second means independent of said first means.
