Abstract
An intragastric device and method of use thereof are provided. The device is actuated to change its volume based on one or parameters detected in the gastric lumen. The device comprises an expandable reservoir that is adapted to distend one or more walls of the gastric lumen for a predetermined time. The device may also be actuated based on a pressure control system in which the reservoir maintains a constant pressure against the walls of the gastric lumen.

14. An intragastric device for the treatment of obesity, the intragastric device comprising:
an expandable reservoir that is configured to change volume while implanted in a gastric lumen, the reservoir being actuated by a pressure controller to change volume in response to a pressure change of the reservoir against one or more walls of the gastric lumen, the reservoir adapted to distend the one or more walls of the gastric lumen for a predetermined time to trigger a sensation of satiety. - View Dependent Claims (15, 16)

17. A method of treatment of obesity, the method comprising the steps of:
-
(a) introducing a reservoir into a gastric lumen, the reservoir having a first volume, (b) detecting a parameter within the gastric lumen, the parameter being indicative of expansion of the gastric lumen; and (c) actuating the reservoir based on the detected parameter such that the reservoir changes from the first volume to a second volume, the second volume being larger than the first volume. - View Dependent Claims (18, 19, 20, 21, 22)
