Abstract: A system includes an adapter, a member and a clip which includes jaws connected to one another such that the jaws are movable between insertion and initial deployed configurations. The member is releasably coupled to the clip and movably connected to the adapter. The member includes a connector at a distal end thereof releasably engages an opening extending through a first jaw such that a longitudinal movement of the member relative to the adapter moves the clip between the insertion configuration, the deployed configuration and toward a review configuration. The member retracts the clip proximally over the adapter so that the clip is forced open as the clip is retracted over the adapter freeing the clip from tissue. The connector includes a deformable portion deforming to release the member from the first jaw toward a final deployed configuration when a distal force exceeds a predetermined threshold value.
