  • a control module including a power source and a remotely operated switch which controls an output from the power source to produce a pressurized inflation medium; and

    an actuator comprising an inflation cuff connectable to receive the pressurized inflation medium from the output on the control module, wherein said cuff is mountable over an exterior of the body lumen and shifts between an open configuration where the body lumen is at least partially open and a closed configuration where the body lumen is closed in response to a change in power from the output controlled by the switch.
