ABSTRACT:
A gastrointestinal sphincter to be surgically implanted around a lumen (e.g. bowel) of a patient to apply variable occlusive pressures for articulating the lumen. The sphincter includes an occlusion cuff having a hollow, expansible chamber formed therein to embrace the lumen. Communicating in a single, continuous fluid circuit with the expansible chamber are first and second fluid circuits having respective reservoir supplies of fluid located therein. Each of the reservoir supplies may be selectively actuated in order that fluid will be delivered to the expansible chamber to controllably expand the chamber and thereby produce variable occlusive pressure levels for achieving coaptive continence. A fluid filled physician control port is interconnected with one of the fluid circuits and surgically implanted so as to be accessible to a fluid filled syringe. A carefully controlled volume of fluid from the port can be delivered to the expansible chamber via the associated fluid path to generate the minimum increased occlusive pressure necessary to achieve coaptive continence according to the tissue requirements of the patient.
