摘要： A urine tube extends through a balloon which is inflatable in the neck of a bladder to form a seal around the urine tube. The balloon has a shape corresponding to the shape of the bladder chamber at the urethra orifice to facilitate establishing a seal. A valve is provided on the outlet end of the urine tube and an air tube extends along the substantial length of the urine tube into the balloon. A hypodermic syringe or the like may be inserted into the inlet end of the air tube for inflating the balloon. A hydrogel collar is positioned around the urine tube against the body at the outlet end of the urethra to hold the balloon in tight engagement with the bladder neck at the urethra orifice.

摘要： An inflatable cuff used as an artificial sphincter may be used in either of two different ways. The first embodiment involves the cuff encircling the urethra for maintaining pressure on it to occlude it except when voiding the bladder. The second embodiment involves placing a one-way valve in the urethra which is encircled by the inflatable cuff such that the cuff is only inflated when it is desired to void the bladder by opening the valve in the urethra through pressure being applied to the exterior of the valve body. 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. Fluid pumped to the cuff through the valve causes a positive pressure on the cuff side of the valve blade elements and a negative pressure on the bulb side which combine to assist in maintaining the valve in a sealed closed condition.

摘要： 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.
