BARIATRIC DEVICE AND METHOD
First Claim
1. A bariatric device comprising:
- a body having a wall defining a lumen, said wall configured to generally conform to the shape and size of at least one chosen from i) the abdominal portion of the esophagus and ii) the proximal cardiac portion of the stomach, said wall adapted to exert a force on the at least one chosen from i) the abdominal portion of the esophagus and ii) the proximal cardiac portion of the stomach thereby influencing a neurohormonal feedback mechanism to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food, anda fixation system to resist distal migration of said body, said fixation system including at least a portion of said wall adapted to promote ingrowth of tissue in said wall.

Abstract
A bariatric device and method of causing at least partial satiety includes a body having a wall defining a lumen. The wall is configured to generally conform to the shape and size of i) the abdominal portion of the esophagus and/or ii) the proximal cardiac portion of the stomach. The wall is adapted to exert a force on the i) abdominal portion of the esophagus and/or ii) the proximal cardiac portion of the stomach thereby influencing a neurohormonal feedback mechanism to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food. A fixation system is included to resist distal migration of the body. The fixation system includes at least a portion of the wall having a tissue ingrowth characteristic to promote ingrowth of tissue in the wall.

11. A bariatric device comprising:
a body having a wall defining a lumen, wherein said wall includes a wall portion defining an esophageal member sized to conform to an abdominal portion of the esophagus, another wall portion defining a cardiac member sized to conform to a proximal cardiac portion of the stomach and a further wall portion extending between said esophageal member and said cardiac member, wherein said esophageal member and said cardiac member are adapted to exert a force on the abdominal portion of the esophagus and the proximal cardiac portion of the stomach thereby influencing a neurohormonal feedback mechanism to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food, wherein at least a portion of said wall is adapted to promote ingrowth of tissue, wherein the ingrowth of tissue at said at least a portion of said wall in reaction to the presence of said body in the recipient fixes said body to the anatomy of the recipient to resist distal migration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of causing at least partial satiety comprising:
-
positioning a body at least one chosen from i) an abdominal portion of the esophagus and ii) a proximal cardiac portion of the stomach, said body having a wall defining a lumen, said wall configured to generally conform to the shape and size of the at least one chosen from i) the abdominal portion of the esophagus and ii) the proximal cardiac portion of the stomach; exerting force with the wall at the at least one chosen from i) the abdominal portion of the esophagus and (ii) the proximal cardiac portion of the stomach thereby influencing a neurohormonal feedback mechanism of the patient to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food; and fixing said body against distal migration including promoting ingrowth of tissue at least a portion of said wall. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
