1. A pressurized inflatable gastric banding system for placement around the stomach of a patient for treating obesity in the patient, comprising:
- a gastric band constructed to be placed around the stomach of the patient;
an inflatable member positioned along an inner surface of the gastric band constructed to adjust an inner circumference of the gastric band, the inflatable member having a pressure P2;
a pressurized inlet reservoir selectively coupled to the inflatable member and constructed to contain a fluid, the inlet reservoir having a pressure P1 that remains greater than or equal to the pressure P2;
an electrically powered inlet valve in fluid communication with the inlet reservoir and the inflatable member, the inlet valve being connected between the inlet reservoir and the inflatable member;
an outlet reservoir selectively coupled to the inflatable member constructed to receive fluid from the inflatable member, the outlet reservoir having a pressure P3 that does not exceed the pressure P2; and
an electrically powered outlet valve in fluid communication with the inflatable member and the outlet reservoir, the outlet valve connected between the inflatable member and the outlet reservoir; and
a controller, coupled to the inlet valve and the outlet valve, constructed to actuate the inlet valve to release the fluid from the pressurized reservoir to control the flow of the fluid from the reservoir to the inflatable member and to actuate the outlet valve to release the fluid from the inflatable member to control the flow of the fluid from the inflatable member to the outlet reservoir, the controller constructed to be remotely controllable from outside of the patient, wherein the gastric band is constructed to form a smoothly surfaced circle around the stomach of the patient, and wherein the controller is constructed to actuate the inlet valve to fluidly couple only the inlet reservoir to the inflatable member and to actuate the outlet valve to fluidly couple only the outlet reservoir to the inflatable member.

Abstract
A remotely controllable gastric banding device (10) for placement around the stomach of a patient for the treatment of obesity. The device (10) comprises a gastric band (10) having an inflatable chamber (16) for adjusting the inner circumference of the band (10), a pressurized reservoir (20) with a valve (31) for providing fluid to inflate the inflation chamber (16), a valve (32) for releasing fluid from the inflatable chamber (16), and a controller (41) for controlling the valves (31, 32). The controller (41) is remotely controllable from outside the patient.
