1. A clipping system for treating tissue, comprising:
an adapter extending longitudinally from a proximal end configured to be mounted over a distal end of an insertion device to a distal end, wherein a distal portion of the adapter is tapered toward the distal end of the adapter;
a clip including first and second jaws, a first end of the first jaw being connected to a first end of the second jaw via a first hinge and a second end of the first jaw being connected to a second end of the second jaw via a second hinge so that the first and second jaws are movable between an insertion configuration, in which the clip is mounted over the adapter so that the first and second jaws are separated from one another to receive tissue therebetween, and an initial deployed configuration in which the first and second jaws are drawn toward one another to grip tissue therebetween, at least one of the first and second hinges being biased to draw the clip toward the initial deployed configuration; and
a first extending member releasably coupled to the clip and movably connected to the adapter to permit a movement of the clip relative to the adapter from the insertion configuration to the initial deployed configuration, the first extending member being configured to permit withdrawal of the adapter proximally away from the clip while the first extending member remains coupled to the clip to place the system in a review configuration in which the clip is physically separated from the adapter to enhance a visual observation of the clip, the first extending member being operable to retract 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 has been clipped, and the first extending member configured to release the clip therefrom in a final deployed configuration, when the clip is observed to be clipped in a desired position.
