Abstract

Suture passers and methods of use. Described herein are suture passers preloaded with suture, including cartridges that couple to a suture passer to form a loaded suture passer that are configured to prevent a length of suture (e.g., already-passed suture) from re-entering the channel of the suture passer jaw and getting recaptured and/or entangled by the tissue penetrator. In particular, described herein are preloaded and automatically re-loading suture passers that are adapted to include a gate, guide, or shield on one of the jaws of the suture passer, and methods of operating such suture passers for surgical use including repairing tissue.
