ABSTRACT:
A body fluid drainage apparatus or shunt for implantation in the inner ear or elsewhere includes an essentially rigid elongated tube having one open end and a closed, flexible end with a valve, a generally rigid housing fixedly secured to and telescoping over the closed end of said elongated tube, a pair of angularly, oppositely extending arms fixedly secured to the assembly, and a pair of plastic films, with open sides, secured to the apparatus enclosing the valve. When the valve is a slit valve, it is sealed in a flexible tube sealed to and extending a short distance beyond the elongated tube.
