ABSTRACT:
A surgically implantable shunt system, including a flow control valve and an antechamber, is provided for controlling the release of entrapped body fluids. The flow control valve includes a pair of molded plastic bases situated, respectively, adjacent to an inlet and an outlet of the valve, which bases are situated within a flexible encasement. Each base includes an outer housing, a valve membrane carrier positioned within the housing, and a flow control member. The flow control members each include a central support and a resilient membrane which is generally arch-shaped and resiliently biased to contact the respective base generally along the outer edge of the membrane in a manner permitting only controlled one-way flow through the valve. The antechamber permits injection of medication into the shunt between a proximal catheter and the distally located flow control valve, and pumping of the medication in either direction.
