  • Patent number: 5234409
    Abstract: A female incontinence control device includes a conduit having inlet and outlet openings for receiving, conducting and discharging urinary fluid. The device also includes structure for holding the conduit in position relative to the urethra such that the inlet opening is adapted to receive substantially all of the urinary fluids which drain from the bladder, and the outlet opening of the conduit is positioned outside the urethra. In one embodiment of the invention, the device can be entirely contained within the labia majora. In other embodiments of the invention the device extends through the urethra to the bladder. In all embodiments of the invention a drainage control valve is positioned within the conduit for location intermediate the urethral orifice and the labia majora for manual actuation to selectively control urinary flow through the conduit.

  • Patent number: 5114398
    Abstract: The female incontinence control device includes a conduit having inlet and outlet openings for receiving, conducting and discharging urinary fluid. The device also includes stabilizing structure for holding the conduit in its installed position relative to the urethra and bladder such that a drainage inlet opening can receive fluid from the bladder, and the outlet discharge opening is positioned outside the urethra. The conduit includes a manually actuatable drainage control valve adapted to be positioned outside the urethra. Manual actuation of the valve from a closed position to an open position is thus easily accomplished by manipulating an actuator member at a distal end portion of the conduit to selectively control urinary discharge from the conduit. The actuator member can be formed as an extension of a valve member or interconnected with the valve member through a flexible connecting link.

  • Patent number: 5030199
    Abstract: A female incontinence control device includes a conduit having inlet and outlet openings for receiving, conducting and discharging urinary fluid. The device also includes stabilizing structure, which can be adjustable, for holding the conduit in its installed position relative to the urethra and bladder such that a drainage inlet opening can receive fluid from the bladder, and the outlet discharge opening is positioned outside the urethra. The conduit includes a magnetically actuatable drainage control valve adapted to be positioned between the urethral orifice and the labia majora. Magnetic actuation of the valve from a normally closed position to an open position is thus easily accomplished by manipulating a portable magnet at a distal end of the conduit outside the urethral opening to selectively control urinary flow through the conduit.
