Artificial Sphincter for Urinary Incontinence in Men

An artificial urinary sphincter (AUS) is an implanted device to treat urinary incontinence in men. The AUS is designed to supplement the function of the natural urinary sphincter that restricts urine flow out of the bladder.

At least one AUS device utilizes a length of tape fixed in a loop around the urethra. A mechanical control device implanted in the scrotum consists of an arrangement of springs that, when activated, constrict the tape loop around the urethra to prevent urine flow. When deactivated by the user, the tape loop relaxes, allowing urine flow.
