Abstract
A bistable penile prosthesis (20) designed to be surgically implanted in the penis for the treatment of erectile impotence. The prosthesis includes an articulated column (26) and an actuator apparatus (30) enclosed within an outer elongated sheath (28). The actuator apparatus (30) is configured and disposed for alternately compressing the articulated column (26) and tensioning a tension member (32) whereby frictional resistance increases causing an erect state, and stretching the articulated column (26) and relaxing the tension member (32) whereby frictional resistance decreases causing a flaccid state under volitional control by the patient. The actuator (30) includes a cam member (68) defining a pathway for travel therealong by a cam follower member (86) in only one direction.
