A bariatric device and method of causing satiety in a patient includes providing a body having a wall defining a lumen. The wall is sized to conform to the shape and size of the abdominal portion of the esophagus and/or at the esophageal-gastric junction and/or the proximal cardiac portion of the stomach of the patient. The wall is adapted to exert radial pressure on the abdominal portion of the esophagus and/or the esophageal-gastric junction, and/or the proximal stomach, or cardia, of the patient. This influences the neurohormonal feedback mechanism present at the distal esophagus and the cardia to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food. |
