Bariatric device and method
First Claim
Patent Images
1. A bariatric device comprising:
- a body having at least two wall portions, each of said wall portions defining a portion of a lumen, said lumen extending through said body;
one of said wall portions defining an esophageal member sized to conform to an abdominal portion of the esophagus;
another of said wall portions defining a cardiac member sized to conform to a proximal cardiac portion of the stomach; and
at least one tension member extending between said esophageal member and said cardiac member;
wherein said cardiac member is tapered outwardly from a proximal portion with respect to the gastrointestinal tract to a more distal portion with respect to the gastrointestinal tract and is adapted to exert a force on the cardiac portion of the stomach;
wherein the force exerted by said cardiac member on the cardiac portion of the stomach influences a neurohormonal feedback mechanism of a patient to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food.

Abstract
A bariatric device includes a body having a wall defining a lumen, the wall configured to generally conform to the shape and size of at least one chosen from i) the abdominal portion of the esophagus, ii) the esophageal-gastric junction, and iii) the proximal cardiac portion of the stomach, with the wall adapted to exert pressure on the at least one chosen from i) the abdominal portion of the esophagus, ii) the esophageal-gastric junction, and iii) 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.

21. A method of causing at least partial satiety in a recipient comprising:
-
providing a body having a wall defining a lumen, said wall tapered outwardly from a proximal portion with respect to the gastrointestinal tract to a more distal portion with respect to the gastrointestinal tract; positioning said body at a proximal cardiac portion of the stomach; and exerting force with said wall on the proximal cardiac portion of the stomach, wherein the force influences a neurohormonal feedback mechanism of the recipient to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
