Abstract: An assembly for a closure device includes a cap with a distal portion having a recess to receive tissue and a proximal portion fitting over a face of an endoscope. The proximal portion includes fold(s) between a first region and a first end of a second region. The cap expands from a collapsed state in which an angle of the first region relative to a longitudinal axis of the endoscope is at a minimum to an expanded state in which the angle is increased. Based on the angle and reflectivity of the first region, an endoscopic camera on the face is provided an increased field of view in the expanded state relative to the collapsed state. The device captures tissue when the cap is in the expanded state via an actuation mechanism extending through a channel of the endoscope into the distal portion.
