Abstract
A cerebrospinal fluid (CSF) shunt valve includes a valve housing and a substantially flat stabilizing member that has a width substantially greater than that of the valve housing. The shunt valve is adapted for surgical implantation under the scalp of a patient to drain excess CSF from the brain. The stabilizing member rests on the skull of a patient and the stabilizing member is effective to prevent rotation of the shunt valve about a longitudinal axis thereof. The shunt valve includes a pressure adjustment mechanism disposed within the housing, for adjusting a threshold pressure at which fluid may flow through the shunt valve.
