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 another via hinges, at least one of the hinges being biased to draw the first and second jaws toward one another, the clip movable relative to the cap between an insertion configuration, in which the first and second jaws extend over opposing portions of the cap so that the first and second jaws are separated from one another to receive a target tissue therebetween, 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 an optical system of the endoscope on which the cap is mounted, and a deployed configuration in which the clip is moved distally off of the clip so that the first and second jaws are drawn toward one another under the bias of the at least one of the hinges to close over tissue received therebetween;
a deployment element extending from a distal end releasably coupled to the clip through the channel of the cap to a proximal end which, in use, remains outside the living body while the cap is adjacent to the target tissue, the deployment element being configured so that a proximal movement of the deployment element relative to the cap moves the clip distally relative to the cap toward the deployed configuration; and
a repositioning element extending from a distal end coupled to one of the cap and the clip proximally through the channel of the cap to a proximal end that, in use, remains outside the living body, the repositioning element being configured so that moving the repositioning element proximally relative to the cap moves the clip proximally relative to the cap from the review configuration to the insertion configuration.
