Patent ID: 8900118

Claim:
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 single valve seat positioned between the inlet and the outlet, the valve seat being in fluid communication with 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, wherein the diaphragm is directly seated on the valve seat in a closed position that blocks the valve seat and blocks fluid communication between the inlet and the outlet, and wherein the diaphragm is not seated on the valve seat in an open position that does not block the valve seat and does not block fluid communication between the inlet and the outlet; an actuator configured to apply a downward force, in a direction from the diaphragm toward the valve seat, 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.
