Abstract

A technique is described for reducing the stomach cavity endoscopically, from within the stomach or, in the alternative, from within the peritoneal cavity via a wall of the digestive tract. This new approach for reducing gastric capacity uses a flexible endoscope and a specially adapted ligating loop that is secured at spaced locations about an inner periphery of the stomach. After attachment, the loop is constricted to draw together the associated gastric wall portions to reduce the food receiving cavity defined at the base of the esophagus. The ligating loop is preferably a slip knotted loop.
