An artificial urinary sphincter (AUS) system that includes a reservoir to hold a fluid, a cuff that includes a pre-shaped spiral tube to be wrapped around a urethra, and a control device to be fluidically coupled to the reservoir and the cuff. The control device regulates transfer of the fluid between the reservoir and the cuff. The cuff receives and dispatches the fluid to expand and contract the pre-shaped spiral tube and to coapt the urethra for continence and open the urethra for voiding.
