Abstract
An adjustable gastric banding device is used for contracting a patient'"'"'s stomach in order to fight obesity. A gastric band (1) of a known type, implanted around the stomach and including a cavity (2) filled with liquid, is connected by a tube (7) to a control box (9) and a balancing reservoir (11) which are implanted under the patient'"'"'s skin. The box (9) contains an electric pump and an electronic control unit capable of communicating by radio with a monitor (13) carried by the patient and with a controller (12) intended for the doctor. The controller can operate the pump by remote control to transfer determined volumes of liquid in a closed circuit from the gastric band to the reservoir or vice versa, to adjust the diameter of a passage in the stomach. The monitor receives and signals alarms from the control box.

11. Method for treating obesity by adjustable gastric banding, including the steps of:
-
(i) implanting in a patient'"'"'s body an assembly including ;
a gastric band arranged around the patient'"'"'s stomach and provided with a cavity of variable volume filled with a liquid, a reservoir, a control box, and a liquid circuit connecting said gastric band cavity to said reservoir via said control box, said box including an electric power source, an electronic control unit and an electric pump arranged in said liquid circuit;(ii) adjusting the gastric band cavity volume by transferring a volume of liquid between said cavity and said reservoir by means of said pump, the transfer being controlled in a non-invasive manner by cordless communication between a control apparatus placed outside the patient'"'"'s body and said electronic control unit. - View Dependent Claims (12)
