Patent abstract
A self adjusting hydrocephalus valve that continuously drains cerebrospinal fluid at a rate which is proportional to the average pressure difference across the valve. The valve employs a ball-in-cone mechanism having an associated biasing element that is insensitive to high frequency pressure variations for regulating the opening of the valve mechanism. The biasing element includes flexible bellows having a preset tension.
