1. A device for treating a target tissue, comprising:
a clip including a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, proximal ends of a pair of clip arms slidably received within the channel so that the pair of clip arms are movable between an open configuration, in which distal ends thereof are separated from one another, and a closed configuration, in which the distal ends thereof are moved toward one another, the capsule further including a cap coupled to a distal end of a longitudinal body so that, when a predetermined force is exerted on the cap via engaging features of the clip arms, the cap is moved from a pre-deployed configuration to the deployed configuration, in which the cap is moved proximally relative to the longitudinal body to reduce a length of the capsule; and
a proximal portion configured to permit insertion of the clip through a working channel of an endoscope, the proximal portion including a flexible shaft extending from a proximal end to a distal end configured to be releasably coupled to the proximal end of the capsule and a control member extending through the flexible shaft to a distal end releasably coupled to the proximal ends of the clip arms so that moving the control member longitudinally relative to the flexible shaft moves the clip arms between the open and closed configurations.
