Bariatric device and method

摘要

A bariatric device and method of causing at least partial satiety in a recipient includes positioning a body in a recipient, the body having a wall defining a lumen, the wall configured to generally conform to the shape and size of the proximal cardiac portion of the stomach. Force is exerted with the wall on the proximal cardiac portion of the stomach in the absence of food thereby activating receptors located in the proximal cardiac portion of the stomach, thereby influencing 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.

主权项

1. A bariatric device, comprising:
a body having a wall defining a lumen for the passage of food; wherein said wall has an esophageal portion that is configured to the size and shape of a portion of the esophagus and a cardiac portion that is configured to generally the shape and size of the proximal cardiac portion of the stomach; a connector connected with said esophageal portion and said cardiac portion, said connector configured to be positioned at the gastro-esophageal junction; said cardiac portion adapted to exert a radial pressure on 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 a fixation system that is adapted to position said cardiac portion of said wall against the cardiac portion of the stomach, said fixation system at least partially positioned at said connector and configured to secure the device at the gastro-esophageal junction of the recipient.
