Abstract

A minimally invasive system and method for providing weight loss by inducing the feeling of satiety whereby an intragastric device is inserted into the gastric lumen via the esophagus and an external magnetic device is used as needed to magnetically attract the intragastric device towards the inner wall of the stomach and impart tactile stimulation sufficient to stimulate the vagus nerve.

Claims (11)

1 . A method of stimulating the anterior gastric wall or vagus nerve comprising the steps of:

inserting a deployable intragastric device containing magnetic material into a stomach of a patient; and positioning an external magnet in close enough proximity to the intragastric device to create a sufficient magnetic pulling force between the external magnet and the intragastric device to move the intragastric device towards, and impart stimulating force upon the vagus nerve.

2 . The method of claim 1 wherein the stimulation is to modulate at least one gastrointestinal hormone.

3 . The method of claim 2 , wherein the at least one gastrointestinal hormone is ghrelin.

4 . The method of claim 2 , wherein the at least one gastrointestinal hormone is leptin.

5 . The method of claim 1 , further comprising inducing interactions between ghrelin, leptin, glucagon-like peptide-1 and peptide YY.

6 . A system comprising:

a transorally administered intragastric device comprising at least one type of magnetic material, and at least one surface capable of deployment inside of a patient's stomach, wherein the intragastric device is equipped to impart tactile stimulation upon a stomach wall of the stomach via an external magnet, and impart stimulating force upon the vagus nerve.

7 . The system of claim 5 , wherein the stimulation is to modulate at least one gastrointestinal hormone.

8 . The system of claim 6 wherein the at least one gastrointestinal hormone is ghrelin.

9 . The system of claim 6 wherein the at least one gastrointestinal hormone is leptin.
