ABSTRACT:
A silicone valve is placed in the orifice of the urethra. The valve tube includes a pair of blade valve elements which extend from the valve side wall forwardly and inwardly. The tube includes a bulb portion in the area of the valve elements to provide pressure cavities for urine to accumulate and apply pressure to the blade elements to maintain them normally closed. Pressure on the opposite sides of the tube walls will open the valve to flow of urine therethrough.
