Abstract
The valve (10) has an elongate, hollow valve body (11) into which a flat plate (14) tightly fits partitioning the valve body into an outlet chamber (16) and an inlet chamber (17) communicating respectively with a drainage catheter and a cerebroventricular catheter (12). The flat plate has a circular aperture (18) connecting the chambers and upon which rests a spherical ball (19). A flat spring (20) biases the ball against the circular periphery of the aperture. Testing for leakage is accomplished by illuminating with light of a suitable frequency the aperture (18), with ball (19) seated therein, and detecting any light transmitted through the aperture. <IMAGE>
