Gastroenterologists would like to remove, through endoscopy, full-thickness lesions in the stomach, but currently there are no surgical devices capable of sealing the wound left after the lesion is removed. This paper describes the design, analysis, and prototyping of a device meant to address this problem. The device is intended to be used in conjunction with currently available endoscopes and comprises five key components including spikes, a beam, a hinge, a latch, and a positioning mechanism. Trials of positioning and placing a clamp on an in vitro pig stomach tissue were successfully completed.
