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.
Claims24
A method of treating obesity in a patient, comprising the steps of:
- implanting a gastric banding device around the stomach of the patient to create a stoma;
- said gastric banding device having an inflatable chamber;
- remotely transmitting control signals from outside of the patient to a controller of the gastric banding device inside of the patient;
- and
- actuating a first valve, between a pressurized fluid reservoir and said inflatable chamber, or a second valve, between said inflatable chamber and an outlet, on the basis of the control signals received by the controller to increase or decrease the fluid volume in said inflatable chamber, wherein the pressure in said pressurized fluid reservoir remains greater than or equal to the pressure in said inflatable chamber, thereby adjusting an inner circumference of the band.
