(A) The new artificial urinary sphincter with conditional occlusion showing individual components: (1) urethral occlusion cuff, (2) pressure-regulating balloon, (3) stress relief balloon, (4) pump and valve assembly unit with self-sealing port for pressurisation. (B) Operation of the new AUS: (1) The urethral occlusion cuff is deflated by squeezing the pump unit located in the scrotum, fluid is transferred to the pressure-regulating balloon and the patient can void through the empty cuff. (2) The cuff re-inflates through a slow return valve; rapid re-inflation can be achieved by squeezing the top of the pump unit. The cuff exerts sufficient pressure to maintain continence without compromising the urethral tissues. (3) During periods of raised intra-abdominal pressure, the fluid from the stress relief balloon is transferred to the cuff to provide additional pressure to maintain continence.
