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 ### Claim 1 A device to deploy surgical fasteners, comprising: a shaft comprising a proximal end, a distal end, and a longitudinal axis between the proximal and distal ends, the distal end of the shaft comprising an exit port; a plurality of fasteners longitudinally arranged in tandem in the shaft, each of the plurality of fasteners being longitudinally spaced apart relative the adjacent fastener; a second fastener arranged in the shaft longitudinally in tandem with and abutting the distal-most fastener of the plurality of fasteners; and a reciprocating drive rod in the shaft having a distal stroke and a proximal stroke, the drive rod being operative to engage and push distally the plurality of fasteners during the distal stroke. ### Claim 2 (depends on 1) The device of claim 1., further comprising an actuator connected to the proximal end of the shaft. ### Claim 3 (depends on 2) The device of claim 2, wherein the actuator is a handle. ### Claim 4 (depends on 1) The device of claim 1, wherein the fasteners are staples. ### Claim 5 (depends on 4) The device of claim 4, further comprising a staple former in the distal in of the shaft. ### Claim 6 (depends on 1) The device of claim 1, wherein the drive rod comprises a plurality of advancers, wherein each of the plurality of fasteners is engaged by one of the plurality of advancers during the distal stroke. ### Claim 7 (depends on 6) The device of claim 6, wherein the advancers do not engage the plurality of fasteners during the proximal stroke. ### Claim 8 (depends on 1) The device of claim 1, a third fastener arranged in the shaft longitudinally in tandem with and abutting the second fastener. ### Claim 9 (depends on 1) The device of claim 1, wherein distal advancement of the plurality of fasteners pushes distally the second fastener towards the exit port. ### Claim 10 A device to deploy surgical fasteners, comprising: a shaft comprising a proximal end, a distal end, and a longitudinal axis between the proximal and distal ends, the distal end of the shaft comprising an exit port; a plurality of fasteners longitudinally arranged in tandem in the shaft, the plurality of fasteners comprising a first group of fasteners longitudinally spaced apart relative the adjacent fastener and a second group of fasteners abutting the adjacent fastener; a reciprocating drive rod in the shaft having a distal stroke and a proximal stroke, the drive rod being operative to engage and push distally the first group of fasteners during the distal stroke. ### Claim 11 (depends on 10) The device of claim 10, wherein the fasteners are staples. ### Claim 12 (depends on 11) The device of claim 11, further comprising a staple former in the distal in of the shaft. ### Claim 13 (depends on 10) The device of claim 10, wherein the drive rod comprises a plurality of advancers, wherein each of the first group of fasteners is engaged by one of the plurality of advancers during the distal stroke. ### Claim 14 (depends on 13) The device of claim 13, wherein the advancers do not engage the plurality of fasteners during the proximal stroke. ### Claim 15 (depends on 10) The device of claim 10, wherein distal advancement of the first group of fasteners pushes distally the second group of fasteners towards the exit port.
