1. A clipping system for treating tissue, comprising:
a cap configured to be mounted over a distal end of an endoscope, the cap extending longitudinally from a proximal end to a distal end and including a channel extending therethrough so that the cap may be located adjacent to target tissue within a living body;
a clip configured to be mounted over the cap, the clip including first and second jaws movably connected to one via a hinge biased to draw the first and second jaws toward one another, the clip movable relative to the cap between: (a) an insertion configuration, in which the first and second jaws extend over the cap so that the first and second jaws are separated from one another to receive a target tissue therebetween and so that obstruction of an optical system of the endoscope on which the cap is mounted is minimized; (b) a review configuration, in which the clip is moved distally relative to the cap so that a portion of the clip extends distally until at least a portion of the clip extends into a field of view of the optical system on which the cap is mounted; and (c) a deployed configuration in which the clip is moved distally off of the cap so that the first and second jaws are drawn toward one another under the bias of the hinge to close and clip tissue received between the first and second jaws; and
a control element extending from a distal end releasably coupled to the clip, through the channel of the cap and the endoscope to which it is connected, to a proximal end which, in use, remains outside the living body while the cap is adjacent to the target tissue, the control element being configured so that movement of the control element proximally through the cap moves the clip distally relative to the cap, the control element being configured so that movement of the control element proximally through the cap via a first distance moves the clip from the insertion configuration to the review configuration and movement of the control element proximally through the cap via a second distance moves the clip from the review configuration to the deployed configuration.
