ABSTRACT:
An implantable valve for the treatment of hydrocephaly is disclosed. The valve includes at least one chamber including a fluid flow orifice capable of being connected to an area within the patient to be drained. The flow orifice is located within a flexible diaphragm which is capable of deforming in response to pressure variations across the valve to compensate for normal variations in pressure and thereby avoid hyperdrainage. The flow orifice is surrounded by a valve seat to receive a spherical member for closing off the flow of fluid therethrough when the pressure differential across the valve is below a predetermined opening pressure. An outflow orifice is configured for connection to a drainage area within the body of the patient and is in fluid communication with the flow orifice to drain excess cerebrospinal fluid when necessary.
