ABSTRACT:
A surgically implantable flow control valve is provided for use in shunt systems for controlling the release of entrapped body fluids. The valve includes a relatively rigid, unitized molded plastic base separating an inlet chamber from an outlet chamber and including one or more apertures passing from the inlet chamber to the outlet chamber, and a resilient membrane which is molded of a material different from the material of the plastic base and which is secured to the base in a manner covering the apertures through the base on the outlet chamber side of the base. Fluid flow occluders on the base facilitate both proximal and distal flushing, and radiopaque indicators and markers permit a surgeon to ascertain specific information about the device and the functioning of the shunt system which would otherwise be unavailable without additional surgery.
