SATIATION DEVICES AND METHODS FOR CONTROLLING OBESITY
First Claim
Patent Images
1. A satiation device configured to be positioned around a portion of a stomach of a patient so as to create a satiation pouch, the device comprising a plurality of mating sections, each mating section including:
- a proximal end portion with an arcuate interior opening;
a distal end portion with an arcuate interior opening; and
a plurality of elongated members extending from the proximal end portion to the distal end portion;
wherein the plurality of mating sections are configured to surround a portion of a stomach and to be secured together to form a chamber with proximal and distal orifices, wherein the stomach portion within the chamber forms a satiation pouch therein to receive food ingested by the patient.

Abstract
Satiation devices for controlling obesity and methods of implanting same are configured to create a small satiation pouch in the proximal portion of the stomach with a narrow passage leading into the lower portion of the stomach. The small satiation pouch is configured to collect a small amount of masticated food from the esophagus and the narrow passage delays emptying of the food from the satiation pouch into the larger part of the stomach, thereby causing a feeling of fullness.
