摘要: An artificial urinary sphincter operable as a single, uncomplicated component, not prone to failure, and easily repaired. Being preassembled, installation is easy through single incision in one site. It incorporates an outer cuff having inner of interconnecting flexible fluid-containing portions. The overlaps itself where spring loaded push button device installed. acts like retractable ball point pen, pushing on the overlapped portion compress portions, shut urethra when first pushed, then alternately relaxing pressure so release upon additional pushing. Circumferential wires pulleys mounted contract relax radially inward cuff, coordinated with relaxation portion.
