An artificial urinary sphincter system has a pressure reservoir attachable to a pump and a conduit attachable between the pump and a cuff. The cuff is formed as a one-piece monolithic polymer structure that is substantially circular in radial cross-section. The cuff has an interior wall connected by a pair of opposing end walls to an exterior wall and includes a closed cavity located between the interior wall and the exterior wall. The cuff has a part line that allows for placement of the cuff around a urethra of a user.
