Abstract: A medical device may comprise a handle, wherein the handle includes a movable body and a main body; a cap configured to be coupled to a distal end of a scope; a patch, wherein the patch is moveable relative to the cap; and a petal body. The patch may be removably coupled to the petal body. The medical device may further comprise an actuator body coupling the patch to the moveable body such that movement of the moveable body extends the patch from the cap. The petal body may be configured to transition between a closed configuration in which the patch is retracted, and an open configuration in which the patch is extended radially-outward from a central longitudinal axis of the scope.

Abstract: A system includes a clip, a first control member, and an adapter including a channel extending from a proximal end to a distal end. The clip includes a base portion mounted over a periphery of the adapter and arms extending distally from the portion. The arms are movable relative to one another between insertion and initial deployed configurations. The first member is releasably coupled to the portion and is movably connected to the adapter so that a longitudinal movement of the first member relative to the adapter moves the clip between the insertion configuration, the initial deployed configuration, and a review configuration. The first member is operable to retract the clip proximally over the adapter toward the insertion configuration so that the arms is forced open as the clip is retracted over the adapter freeing the clip from tissue on which it had been clipped.
