The device also includes a reservoir (11) designed to be implanted in the patient's body and to be connected to the control box (9), or incorporated in it. The control box (9) has an electrical energy source (37), an electronic control unit (28) and an electrically driven pump (22,44) controlled by the unit (28), so as to transfer liquid in a closed circuit between the reservoir (11) and the cavity (2) of the gastric strap (2). |
