1. An implantable device for controlling movement of a fluid to an inflatable portion of a gastric band, the implantable device comprising:

  • a body having an inlet, an outlet and a valve seat positioned between the inlet and the outlet, the body defining a fluid passage from the inlet to the outlet;

    a diaphragm having one or more edges coupled to the body, the diaphragm being made of an elastomeric material and capable of being moved from a closed position that blocks the valve seat and does not allow the fluid to move from the inlet to the outlet to an open position that does not block the valve seat and allows the fluid to move from the inlet to the outlet;

    an actuator configured to apply a force on the diaphragm causing the diaphragm to move from the closed position to the open position; and

    a microcontroller coupled to the actuator, the microcontroller configured to receive a telemetric signal from a remote transmitter and control the actuator based on the telemetric signal.
