A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween.

What is claimed is: 1. A surgical clip applier, comprising: a housing having a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof; a clip track disposed within the elongate shaft and adapted to seat at least one surgical clip; a feeder shoe slidably disposed within the clip track and adapted to drive at least one surgical clip through the clip track, the feeder shoe having a tang adapted to engage the clip track to prevent proximal movement of the feeder shoe within the clip track, the tang being adapted to allow distal movement of the feeder shoe within the clip track; and a feed bar adapted to advance the feeder shoe distally and to advance a clip into the opposed jaws. 2. The surgical clip applier of claim 1, wherein the feed bar is adapted to initiate advancement of a clip into the opposed jaws prior to initiating advancement of the feeder shoe distally. 3. The surgical clip applier of claim 1, wherein the clip track includes a plurality of openings formed therein for receiving the tang to prevent proximal movement of the feeder shoe within the clip track. 4. The surgical clip applier of claim 1, further comprising a feed bar slidably disposed within the elongate shaft and coupled to the trigger such that movement of the trigger toward a closed position is adapted to advance the feed bar distally thereby advancing the feeder shoe distally. 5. The surgical clip applier of claim 4, wherein a distal end of the feed bar includes an advancer adapted to engage a distal-most clip and to drive the distal-most clip between the jaws. 6. The surgical clip applier of claim 5, wherein the advancer is adapted to remain engaged to a distal-most clip as the clip is closed between the opposed jaws. 7. The surgical clip applier of claim 5, wherein the feed bar includes a plurality of detents formed therein and adapted to engage the tang to move the feeder shoe distally when the feed bar is moved distally. 8. The surgical clip applier of claim 4, wherein the feed bar is coupled to the trigger by a trigger insert mated to the trigger and a link extending between the trigger insert and a proximal end of the feed bar. 9. The surgical clip applier of claim 8, wherein the proximal end of the feed bar includes a coupler that is adapted to receive a portion of the link. 10. A clip advancing assembly for use with a surgical clip applier, comprising: a clip track adapted to seat at least one clip; a feeder shoe adapted to slidably mate to the clip track, the feeder shoe including a tang adapted to engage the clip track to prevent proximal movement of the feeder shoe within the clip track, the tang being adapted to allow distal movement of the feeder shoe within the clip track; and a feed bar adapted to advance the feeder shoe relative to the clip track to move at least one clip disposed within the clip track in a distal direction, and the feed bar being adapted to advance a distal-most clip disposed within the clip track into a jaw assembly. 11. The clip advancing assembly of claim 10, wherein the clip track includes a plurality of openings formed therein for receiving the tang to prevent proximal movement of the feeder shoe within the clip track. 12. The clip advancing assembly of claim 10, wherein the feed bar is adapted to couple to a movable trigger formed on a housing of a surgical clip applier and adapted to slidably move distally when the trigger is closed to advance the feeder shoe and at least one clip disposed within the clip track. 13. The clip advancing assembly of claim 12, wherein a distal end of the feed bar includes an advancer adapted to engage a distal-most clip and to drive the distal-most clip from the clip track and into jaws formed on a distal end of a surgical clip applier. 14. The clip advancing assembly of claim 12, wherein a proximal end of the feed bar includes a coupler adapted to receive a link for coupling the feed bar to a trigger of a surgical clip applier. 15. The clip advancing assembly of claim 10, wherein the feed bar includes a plurality of detents formed therein and adapted to engage the tang to move the feeder shoe distally when the feed bar is moved distally. 16. A clip advancing assembly for use with a surgical clip applier, comprising: a clip track adapted to seat at least one clip; a feeder shoe adapted to slidably mate to the clip track; a feed bar adapted to advance the feeder shoe relative to the clip track to move at least one clip disposed within the clip track in a distal direction, and the feed bar being adapted to advance a distal-most clip disposed within the clip track into a jaw assembly ; and a jaw retainer shaft coupled to the clip track and having a proximal end that is adapted to removably mate to an outer tube that houses the clip track, feeder shoe, and feed bar. 17. The clip advancing assembly of claim 16, wherein the proximal end of the jaw retainer shaft is compressible, and wherein the feed bar is adapted to prevent compression of the proximal end of the jaw retainer shaft when the feed bar is in a predetermined position relative to the clip track. 18. The clip advancing assembly of claim 17, wherein the proximal end of the jaw retainer shaft includes an opening formed therein and adapted to allow the jaw retainer shaft to compress upon insertion thereof into the outer tube, and wherein a proximal end of the feed bar includes at least one protrusion formed thereon and adapted to extend into the opening to prevent compression of the proximal end of the jaw retainer shaft when the feed bar is in a predetermined position relative to the jaw retainer shaft.
