Abstract
An artificial sphincter apparatus and method, the artificial sphincter including a pair of parallel, coaxially mounted rings with at least one ring rotatable relative to the other ring. A plurality of tie members mounted circumferentially to the rings extend between the rings and are angularly moved relative to the axis of the artificial sphincter upon relative rotation between the rings so as to selectively occlude or open a bowel engaged by the artificial sphincter. An actuator mechanism mounted on the artificial sphincter permits the artificial sphincter to be operated externally even when the artificial sphincter is implanted.
