A device for treating tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, the capsule releasably coupled to a proximal portion of the device and clip jaws, proximal ends of which are slidably received within the channel of the capsule so that the clip jaws are movable between an open configuration and a closed configuration. Clip jaws are configured so that a distance between the distal ends of the clip jaws in an open configuration is between 15 and 18 millimeters. Clip jaws further include barbs extending from a distal portion thereof.
