摘要

An inflatable medical instrument (18) for tissue damage in gastric reduction surgery includes a main chamber (20) composed of a biocompatible material capable of being selectively inflated. The medical instrument also includes a longitudinally extending tab member (26) secured to an outer surface of the main chamber, a series of suction holes (30) are formed along the tab member and an electrode (38) is mounted on the tab member. The present invention also provides a method for forming a tissue junction used in defining a gastric pouch including damaging opposed tissue layers, apposing the tissue layers and fastening the tissue layers to allow the tissue layers to heal together.
