Abstract
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.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
160 words
The method of controlling urine flow in the urethra comprising the steps of; providing a tubular one way valve having a valve body with oppositely extending inlet and outlet tube portions, said valve body having converging blade valve elements normally closed to flow in one direction and being operable to flow in said one direction by application of external pressure on opposite sides of the valve body to open the valve elements, orienting the valve for insertion of said inlet tube portion into the urethra outlet orifice such that urine flow from the bladder to the outlet orifice of the urethra will be resisted, positioning the inlet tube portion of the valve in the outlet orifice of the urethra with the valve being remote to the bladder, and operating the valve to allow flow from the bladder through the valve by applying pressure on opposite sides of the valve body to spread the valve elements thereby allowing urine flow therethrough.
