First Claim
1. A surgical clip applier, comprising:
- an elongate shaft having opposed jaws formed on a distal end thereof;
an advancer assembly disposed within the elongate shaft and configured to advance one of a plurality of clips disposed within the elongate shaft into the opposed jaws, the advancer assembly being movable between a proximal position and a distal position; and
a feeder shoe disposed within the elongate shaft and configured to engage and prevent the advancer assembly from moving to the proximal position after the advancer assembly has moved to the distal position to advanced a proximal-most clip into the opposed jaws.

Abstract
A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one embodiment, a surgical clip applier is provided and can include a housing having a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof. The clip applier can include an advancer assembly disposed within the elongate shaft and configured to advance one of a plurality of clips disposed within the elongate shaft into the opposed jaws. A feeder shoe can be disposed within the elongate shaft and can be configured to engage and prevent the advancer assembly from moving to a proximal position after the advancer assembly has moved to a distal position to advance a proximal-most clip into the opposed jaws. This can indicate to a user that a clip supply of the surgical clip applier is depleted.
