This paper is a study on the development of an artificial urethral valve for treatment of urinary incontinence which occurs frequently in the aged. Urinary incontinence is caused by the weakening of the urinary canal sphincter muscles and the expansion of the prostate gland, and occurs in persons of all ages from infants to the aged. The prototype urethral valve was assembled in hand-drum form with four thin nitinol (nickel-titanium alloy) plates with a thickness of 0.3 mm. Animal experiments show the prototype urethral valve controls well the opening and closing functions of the canal.
