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 method for advancing a surgical clip through an elongate shaft of a surgical clip applier, comprising: distally advancing a feed bar within the elongate shaft of the surgical clip applier such that the feed bar, which includes a plurality of detents, drives a distal-most clip disposed within the elongate shaft into a jaw assembly, and such that the feed bar directly engages and distally drives a feeder shoe disposed within the elongate shaft by one of the plurality of detents engaging a first tang on the feeder shoe and thereby distally advances at least one additional surgical clip disposed within the elongate shaft without the feed bar contacting the at least one additional surgical clip. 2. The method of claim 1, wherein the feed bar initiates advancement of the distal-most clip prior to initiating advancement of the feeder shoe. 3. The method of claim 1, further comprising proximally retracting the feed bar within the elongate shaft while the feeder shoe is maintained in a substantially fixed position. 4. The method of claim 1, wherein the step of distally advancing the feed bar includes actuating a trigger coupled to a housing mated to a proximal end of the elongate shaft. 5. The method of claim 1, wherein a distal end of the feed bar includes an advancer for engaging and advancing the distal-most clip into the jaw assembly. 6. The method of claim 1, wherein the feeder shoe is slidably disposed within a clip track that is adapted to seat a plurality of surgical clips. 7. The method of claim 1, wherein the feeder shoe includes a second tang that engages an opening in a clip track of the elongate shaft, the opening preventing the feeder shoe from moving proximally. 8. The method of claim 1, wherein the first tang on the feeder shoe engages a different one of the plurality of detents each time it is moved distally by the feed bar. 9. The method of claim 1, wherein the feed bar moves proximally after it drives the distal-most clip into the jaw assembly. 10. A method for advancing a surgical clip, comprising: actuating a trigger on a clip applier device to distally advance a feed bar within an elongate shaft and thereby advance a distal-most clip into opposed jaws formed on a distal end of the elongate shaft, the feed bar having a plurality of detents that directly engage a feeder shoe to distally advance the feeder shoe and at least one additional clip through the elongate shaft without contacting the at least one additional clip. 11. The method of claim 10, wherein the feeder shoe includes a tang that engages one of the plurality of detents in the feed bar. 12. The method of claim 10, wherein the feed bar initiates advancement of the distal-most clip into the opposed jaws prior to initiating advancement of the feeder shoe. 13. The method of claim 10, wherein distally advancing the feed bar includes squeezing the trigger, the trigger being coupled to the elongate shaft. 14. The method of claim 13, wherein releasing the trigger retracts the feed bar proximally. 15. The method of claim 14, wherein the feeder shoe remains stationary as the feed bar retracts proximally. 16. A method for advancing surgical clips within a clip applier, comprising: closing a trigger to advance a feed bar distally to move a distal-most clip into opposed jaws of the clip applier, the feed bar directly engaging a feeder shoe disposed proximal to a proximal-most clip to move the feeder shoe distally without the feed bar contacting the proximal-most clip, the feeder shoe having a tang that engages one of a plurality of detents formed in the feed bar during distal movement thereof; andopening the trigger to retract the feed bar proximally, the feed bar disengaging from the feeder shoe such that the feeder shoe remains stationary as the feed bar moves proximally. 17. The method of claim 16, wherein the feed bar initiates movement of the distal-most clip into the opposed jaws before initiating movement of the feeder shoe distally. 18. The method of claim 16, wherein distal movement of the feeder shoe advances the proximal-most clip distally within a clip track of the clip applier.
