Abstract: Device and method for correcting urinary incontinence and urinary retention, by implanting a urinary flow control device for elective user control of urinary function in male and female patients. The device is a mechanical valve to a natural or artificial bladder, and includes a to reach the abdominal wall of the patient. Preferably a bladder anti-prolapse skirt is attached between the bladder and control valve. The device provides a urine flow channel that passes through the valve from one side to the other of a valve seat where an actuator with a mating stopper is controlled to open and close the valve at the election of the user with an external controller. The valve is an occlusion type (seat with stopper), or a pinch type. The flow channel may be an artificial urethra passing through a pinch valve.
