Repositional clip with extension

A clipping system for treating tissue, comprising:

• an endoscope including a shaft extending longitudinally from a proximal end to a distal end;
• an adapter including a proximal portion mounted over the distal end of the shaft of the endoscope and a distal portion extending distally from the proximal portion;
• a clip circumferentially mounted on the adapter and including first and second jaws, each of the pair of jaws extending along a curve from a first end to a second end, first ends of the pair of jaws connected to one another via a first hinge and second ends of the pair of jaws connected to one another via a second hinge so that the pair of jaws are movable between an open insertion configuration, in which the pair of jaws are separated from one another, and a closed configuration, in which the pair of jaws are moved toward one another;
• a deployment member configured to move the clip distally relative to the adapter from the open insertion configuration to an initial deployed configuration by moving the clip distally off of the adapter so that the clip is moved toward the closed configuration;
• and
• first and second extending members extending from proximal ends accessible to a user via a user interface at the proximal end of the shaft to distal ends releasably coupled to the clip, so that a distal movement of the first or second extending member relative to the endoscope moves the clip distally away from a distal end of the adapter from the initial deployed configuration to a review configuration by a distance selected so that the clip is visible via the endoscope.

A method for treating tissue, comprising:

• inserting a clip to a target area in a body lumen via an endoscope, the clip circumferentially mounted on an adaptor over a distal end of an endoscopic shaft, in an open insertion configuration in which jaws of the clip are separated from one another;
• applying a suction force through a working channel of the endoscope so that tissue is drawn into a channel of the adapter and between the jaws of the clip;
• moving the clip from the open insertion configuration to an initial deployed configuration by pushing the clip distally off of the adapter through a deployment member so that the jaws revert to a biased closed configuration, in which the jaws extend toward one another to grip the tissue received therebetween;
• and
• moving extending members, distal ends of which are releasably coupled to the clip, distally relative to the endoscopic shaft so that the clip is moved distally away from a distal end of the adapter toward a review configuration in which the clip is visible via the endoscope.
