Method and apparatus for creating a restriction in the stomach or other anatomical structure

摘要

A method is for restricting food volume capacity of the stomach. The method comprises manipulating tissue from within the stomach to create an upper pouch and a lower pouch, and the tissue between the upper pouch and the lower pouch forming an opening therethrough, the upper pouch configured adjacent the gastroesophageal junction, the lower pouch configured adjacent the pylorus, and the opening having a periphery formed by drawing together the tissue. A device for creating a restriction in the stomach. The device comprises a retractor configured for deployment through the esophagus into the stomach; a plurality of arms selectively deployable from the retractor, each of the plurality of arms configured to position a securement device adjacent to a given location of tissue of the stomach from within the stomach; and deployment means for deploying the securement device positioned by each of the plurality of arms to the given location of the tissue of the stomach from within the stomach.
