Shock dampening biocompatible valve
First Claim
1. A biocompatible valve for implanting in a biological organism to confine flow of a biological fluid to a single direction, the valve comprising:
- a mount affixable to the organism, said mount having a first aperture and a second aperture formed in opposing relationship therein for allowing the fluid to flow longitudinally through said mount;
a valve mechanism operable into one of an open position and a closed position, said valve mechanism having formed therein an orifice coaxially aligned with said first aperture and said second aperture of said mount, said valve mechanism longitudinally displaceable in said mount between said first aperture and said second aperture; and
a dampening mechanism coupled to said mount and operable to dissipate energy at said orifice transferred to said valve mechanism by a mechanical transition thereof.

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.
