ABSTRACT:
The prosthetic sphincter includes a manually controllable actuating component for implantation at a convenient location in a patient's body. This actuating component is mechanically connected through a force applying cable to a responsive component positioned about an elimination passage in the patient such as the distal intestine. The actuating component is in the form of a ring so that manual squeezing of opposite portions causes an elongation of the ring to pull on the cable and thereby open up an occlusion orifice in the responsive component. The actuating component in the form of the ring can upon manual manipulation return to its circular form and thereby permit closing of the occlusion orifice in the responsive component. No batteries or electrical components are required for operating the prosthetic sphincter and no resection of luminal tissue is required for its implementation.
