An artificial urinary sphincter made of two-way shape memory NiTi alloy embedded in silicon rubber is designed for prosthesis surgery in case of patients who suffer from urinary incontinence. The metallic part curves down when actuated by electrical current and straightens up when the current stops. This produces a smart composite for urination control in patients inflicted with spinal cord injury.
