ABSTRACT:
A valve assembly for relieving intracraneal pressure includes a valve housing adapted for implantation and having an inlet port for connection to a ventricular catheter and an outlet port for connection to a venus or peritoneal catheter. The valve housing includes a fluid passage, the flow through which is controlled by a first pressure responsive valve of relatively high resistence and a second pressure responsive valve of relatively low resistence spaced downstream of said first pressure responsive valve. An attitude responsive valve is disposed in said fluid passage in parallel with said first pressure responsive valve. The valve assembly is implanted in a patient with the attitude responsive valve in a closed position when the patient is in an upright position and in an open position when the patient is in a horizontal position. The employment of pressure responsive and attitude responsive valves in parallel provides ventricular pressure relief regardless of the patient's position.
