  • Patent number: 6042535
    Abstract: A urethral valve system includes a valve balloon that inflates to provide continence and deflates to allow urine to flow around the balloon and an attached catheter that extends through the urethra, and out of the body through the meatus. The urine cleanses the valve balloon, the catheter and the urethra of bacteria, and thus, minimizes infection. The catheter includes a check valve at the end that is accessible to the user. To inflate the balloon, the user attaches to the check valve a small pump that supplies air or a liquid such as water to inflate the balloon. To deflate the balloon, the user manipulates the check valve to allow the water or air to drain from the balloon. The valve balloon may be positioned in the bladder. To retain the system in the bladder when urine flows around the balloon and the catheter, the balloon deflates to a shape that is wider than the diameter of the neck of the bladder.

In each embodiment a syringe-type pump bulb is used which is connected to a one-way valve in turn connected to a tube to the inflatable cuff. The bulb side wall has sufficient memory to cause it to return to its normal expanded condition which causes the suction of fluid from the cuff when the manually operated valve is actuated.

  • Patent number: 5888188
    Abstract: A mechanical sphincter device is to be located in the body for engaging the urethra to control urinary incontinence. The device is formed by a curved piece of flexible material having free ends and a pair of juxtaposed strips of flexible material having their ends connected to the corresponding ends of the curved piece with the urethra disposed between opposing faces of the strips. When the curved piece is in a relaxed state it tensions the strips to apply pressure to the urethra therebetween to restrict flow of urine and when force is applied to the curved piece relaxing the tension on said pair of strips the pressure on the urethra is reduced and permits urine flow.
