ABSTRACT:
A semi-automatic functioning artificial sphincter including a means for occluding a body passage, a fluid reservoir, and a mechanism for transferring fluid between the occluding mechanism and the fluid reservoir, wherein the sphincter also includes a lock-out mechanism for occluding fluid flow between the fluid reservoir and the inflatable cuff and the occluding mechanism. The occluding mechanism is preferably a valve which is positioned in the fluid path between the reservoir and the occluding mechanism. The valve may be either manually or hydraulically actuated to control one or more aspects of fluid flow through the valve.
