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.

1. A clip advancing assembly for use with a surgical clip applier, comprising: a clip track adapted to seat at least one clip, the clip track having a plurality of openings formed therein for receiving a distal tang to prevent proximal movement of the feeder shoe within the clip track;a feeder shoe
1. A clip advancing assembly for use with a surgical clip applier, comprising: a clip track adapted to seat at least one clip, the clip track having a plurality of openings formed therein for receiving a distal tang to prevent proximal movement of the feeder shoe within the clip track;a feeder shoe slidably coupled to the clip track and having a proximal tang and the distal tang, the distal tang being configured to allow distal movement of the feeder shoe relative to the clip track to drive at least one surgical clip through the clip track while preventing proximal movement of the feeder shoe within the clip track; anda feed bar adapted to engage the proximal tang to advance the feeder shoe distally and to advance a clip into the opposed jaws. 2. The clip advancing assembly of claim 1, wherein the feeder shoe is disposed within the clip track. 3. The clip advancing assembly 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. 4. The clip advancing assembly of claim 1, wherein the feed bar is slidably disposed within an elongate shaft and coupled to a 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 clip advancing assembly 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. 6. The clip advancing assembly of claim 5, wherein the proximal end of the feed bar includes a coupler that is adapted to receive a portion of the link. 7. The clip advancing assembly of claim 1, 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. 8. The clip advancing assembly of claim 7, wherein the advancer is adapted to remain engaged to a distal-most clip as the clip is closed between the opposed jaws. 9. 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 slidably coupled to the clip track and having a proximal tang and a distal tang, the distal tang being configured to allow distal movement of the feeder shoe relative to the clip track to drive at least one surgical clip through the clip track while preventing proximal movement of the feeder shoe within the clip track; anda feed bar adapted to engage the proximal tang to advance the feeder shoe distally and to advance a clip into the opposed jaws, the feed bar including a plurality of detents formed therein and adapted to engage the proximal tang to move the feeder shoe distally when the feed bar is moved distally. 10. 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 configured to seat at least one surgical clip;a feeder shoe slidably coupled to the clip track and configured to drive at least one surgical clip through the clip track when the trigger is squeezed toward the housing, the feeder shoe having proximal and distal tangs; anda feed bar adapted to engage the proximal tang to advance the feeder shoe distally and to advance a clip into the opposed jaws;wherein the distal tang is configured to engage the clip track to prevent proximal movement of the feeder shoe within the clip track and to allow distal movement of the feeder shoe within the clip track. 11. The surgical clip applier of claim 10, wherein the clip track includes a plurality of openings formed therein for receiving the distal tang to prevent proximal movement of the feeder shoe within the clip track. 12. The surgical clip applier of claim 10, wherein the feed bar is adapted to move distally when the trigger is squeezed toward the housing to advance the feeder shoe within the clip track. 13. The clip advancing assembly of claim 12, wherein the feed bar is adapted to advance a distal-most clip disposed within the clip track into the opposed jaws. 14. The surgical clip applier of claim 13, 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. 15. The surgical clip applier of claim 12, wherein the feed bar includes a plurality of detents formed therein configured to engage the proximal tang to move the feeder shoe distally when the feed bar is moved distally. 16. The surgical clip applier 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 the trigger. 17. A surgical clip applier, comprising: an elongate shaft having a handle on a proximal end and opposed jaws on a distal end;a trigger movably coupled to the handle;a clip track disposed within the elongate shaft and configured to hold at least one surgical clip; andan elongate feed bar coupled to the trigger and extending through the elongate shaft between the proximal end and the distal end of the elongate shall, the feed bar being configured to move distally when the trigger is squeezed toward the handle to advance the at least one surgical clip through the clip track and to advance a distal-most clip into the opposed jaws; anda feeder shoe disposed within the clip track and configured to advance the at least one surgical clip through the clip track, the feeder shoe being configured to maintain contact with and not disengage from the feed bar during proximal and distal movement of the feed bar. 18. The surgical clip applier of claim 17, wherein the feed bar is adapted to advance the feeder shoe within the clip track to advance the at least one surgical clip through the clip track. 19. The surgical clip applier of claim 18, wherein the feeder shoe is slidable distally within the clip track and is prevented from moving proximally within the clip track.
