ABSTRACT:
An implantable apparatus for controlling the flow of body fluids through a body passage includes a cuff which can be inflated with pressurizing fluids to close the body passage, a push button actuated and expandible reservoir for the pressurizing fluid and tubing connecting the cuff and the reservoir to form a closed system. The reservoir includes a pumping chamber having a tension spring positioned therein and a push rod located outside the pumping chamber. The push rod is attached to a push button which when actuated expands the volume of the reservoir to receive pressurizing fluids from the cuff thereby allowing the cuff to deflate and the body passage to open.
