DOME AND SCREW VALVES FOR REMOTELY ADJUSTABLE GASTRIC BANDING SYSTEMS
First Claim
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.

Abstract
An implantable device controls the movement of fluid to an inflatable portion of a gastric band. The implantable device includes a body. The body has an inlet, an outlet and a valve seat positioned between the inlet and the outlet. The body defines a fluid passage from the inlet to the outlet. The implantable device also includes a diaphragm. The diaphragm has one or more edges coupled to the body. The diaphragm is made of an elastomeric material and capable of being moved between a closed position that blocks the valve seat and does not allow the fluid to move from the inlet to the outlet and an open position that does not block the valve seat and allows the fluid to move from the inlet to the outlet.

11. An implantable device that controls the movement of fluid to an inflatable portion of a gastric band, the implantable device comprising:
-
a body having an inlet, an outlet and a valve seat, the body defining a fluid passage from the inlet to the outlet; a valve seal having one or more edges coupled to the body, the valve seal being made of an elastomeric material and capable of being moved from an open position that does not block the valve seat and allows the fluid to move from the inlet to the outlet to a closed position that blocks the valve seat and does not allow the fluid to move from the inlet to the outlet; and an actuator having an actuator body defining a threaded screw hole and positioned within the body and a screw positioned within the threaded screw hole, the screw configured to apply a force on the valve seal causing the valve seal to move from the open position to the closed position when the actuator receives a telemetric signal from a remote transmitter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
