摘要： A system for treating tissue includes an applicator including a catheter and a control member extending therethrough, the control member longitudinally movable relative to the catheter and including an abutment structure proximate a distal end thereof, and a clip assembly releasably coupleable to a distal end of the applicator, the clip assembly including a pair of clip arms, a proximal end of each of the clip arms slidably received within a channel of a capsule and configured to be releasably coupled to the distal end of the control member so that the clip arms are movable relative to the capsule between a tissue receiving configuration and a tissue clipping configuration, the capsule including proximal tabs movable between a biased non-engaging and an engaging configuration, in which the proximal tabs engage an engaging portion of the lumen of the catheter, when the abutment structure is received within the capsule.

摘要： A system for treating tissue includes a clip assembly including clip arms movable relative to a channel of a capsule so that the clip arms are movable between a tissue receiving configuration and a tissue clipping configuration. Also, the system includes an applicator releasably coupleable to the clip assembly. The applicator includes a bushing and a control member extending therethrough. The bushing includes deflectable fingers, each of the fingers including an engaging feature at a distal end thereof to engage a corresponding engaging feature of the capsule of the clip assembly and assembled with a pusher element configured to push the fingers to a radially outward position. The pusher element includes a U-shaped portion curving into a channel of the bushing and a longitudinal portion extending distally therefrom. A cam washer is slidable over a length of the control member and positioned distally of the U-shaped portion.
