Title: Prosthetic urinary sphincter control device

Abstract: A device for controlling flow of fluid to and from a resilient inflatable cuff implanted about the urethra to control flow of urine therethrough. The device comprises a housing of rigid material that provides an expansible sealed chamber, a piston forming one wall of the chamber and spring pressed to a position for decreasing the volume of the chamber to thereby force fluid from the chamber to the cuff, manually operable means for moving the piston to another position for enlarging the chamber to permit deflation of the cuff by return of fluid to the chamber, and a flexible cover or envelope encapsulating the housing, piston and manually operated means.
