Endoscopic suture cinch system with replaceable cinch

摘要

A suture cinch, cinch applicator, and cinch loader for loading the cinch into the cinch applicator are provided and permit re-use of the applicator with multiple cinches during an endoscopic procedure. The applicator can be loaded with a first cinch, apply the first cinch onto a portion of suture to fix the portion of suture relative to anatomical tissue, reloaded with a second cinch optionally using the loader, and subsequently used to apply the second cinch to fix another portion of suture to fix the other portion of suture relative to anatomical tissue. The cinch is a tubular member through which the suture can be advanced when the cinch is loaded within the applicator. The cinch defines multiple ribs and cutter defined in a wall thereof. Operation of the applicator deforms the ribs inward to retain the cinch on the suture, and displaces the cutter to sever the suture.
