A biocompatible valve ( 200 ) includes a valve mechanism ( 250, 230 a, 230 b), 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 ( 230 a, 230 b) is received. Upon a transition from an open position to a closed position of the closing mechanism ( 230 a, 230 b), 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.
