1. A method of retaining an obesity-controlling device within a stomach of a patient, comprising the steps of:
- drawing a first tissue region into contact with a second tissue region;
attaching the first and second tissue regions; and
coupling an obesity-controlling device to the tissue regions, the obesity-controlling device defining a bi-directional flow path in the gastro-esophageal junction region, the obesity-controlling device proportioned to restrict movement of food into the stomach such that ingested food moves into the stomach at a rate that is slower than a rate at which food would move into the stomach in the absence of the obesity-controlling device.

Abstract
A device for inducing weight loss in a patient includes a tubular prosthesis positionable at the gastro-esophageal junction region, preferably below the z-line. In a method for inducing weight loss, the prosthesis is placed such that an opening at its proximal end receives masticated food from the esophagus, and such that the masticated food passes through the pouch and into the stomach via an opening in its distal end.

8. A method of retaining an obesity-controlling device within a stomach, comprising the steps of:
-
drawing a first tissue region into contact with a second tissue region; attaching the first and second tissue regions; and coupling an obesity-controlling device to the tissue regions, the obesity-controlling device proportioned to restrict movement of food into the stomach such that ingested food moves into the stomach at a rate that is slower than a rate at which food would move into the stomach in the absence of the obesity-controlling device, wherein the obesity-controlling device includes a chamber and wherein the method includes the step of introducing inflation fluid into the chamber to inflate the obesity-controlling device.
