Abstract
A system includes an adapter mounted over a distal end of an insertion device, a clip and a first extending member. The clip includes jaws movable between an insertion configuration, with the jaws separated and an initial deployed configuration with the jaws drawn together. The clip is biased toward the initial configuration. The first jaw includes a connection element and a first member releasably coupled to the first jaw connection element permits movement of the adapter relative to the clip while the first member remains coupled to the clip to enhance visual observation of the clip. The first 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 on which it had been clipped.
