Clip applier with migrational resistance features
First Claim
1. A surgical method, comprising:
- advancing opposed jaws on a distal end of an elongate shaft of a surgical device into a body;
positioning tissue between the opposed jaws such that the tissue is received within a recess formed in a distal end of a tissue stop disposed between the opposed jaws; and
actuating the surgical device so as to distally advance an advancer along an alignment mechanism on the tissue stop that is proximal to the recess, the distal advancement of the advancer causing a clip to be distally advanced along the alignment mechanism and into the opposed jaws, the advancer and the alignment mechanism each contacting and maintaining the clip in alignment with the opposed jaws as opposed legs of the clip are clipping the tissue between the opposed jaws and until the clip is fully closed.

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 exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and a 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. The surgical clip applier can include a variety of features to facilitate use of the device, including features to align a clip with the jaws, features to prevent unintentional migration of a clip, and features to prevent clip fallout during formation.
