ABSTRACT:
A biocompatible valve (200) includes a valve mechanism (250, 230a,230b), which is mounted and is longitudinally displaceable within a valve mount (210) affixed to a recipient patient. A valve annulus (250) defines an orifice (240) in which a closing mechanism (230a,230b) is received. Upon a transition from an open position to a closed position of the closing mechanism (230a,230b), hydraulic shock is introduced into the fluid passing through the valve. The present invention provides a dampening mechanism (280) to mitigate the shock and to dissipate its energy. Various embodiments allow for high order frequency response through relationships between dampening mechanism components.
