Abstract

A bariatric device includes an esophageal member having an esophageal surface that is configured to generally conform to the shape and size of a portion of the esophagus and an anchoring technique anchoring the esophageal member to the portion of the esophagus. The bariatric device includes a cardiac member having a cardiac surface that is configured to generally conform to the shape and size of a portion of the cardiac portion of the stomach and a connector connected with the esophageal member and the cardiac member to cause strain to be applied by the cardiac member to the cardiac portion of the stomach. The strain applied by the cardiac member to the cardiac portion of the stomach causes satiety in the absence of food. The connector is adapted to pass through the gastroesophageal junction while leaving a continuous portion of the gastroesophageal junction substantially unrestrained.
