1. An artificial heart valve, adapted for replacement of a heart valve of at least one of a human and an artificial heart, comprising:

  • means for securing the heart valve to a selected portion of the heart, said heart valve securing means including an orifice ring having an inlet aperture, an outlet aperture, a generally cylindrical channel operatively coupling said inlet aperture and said outlet aperture for defining an occludable space, said channel having a central longitudinal axis therethrough;

    stator means including a plurality of stator blades operatively secured within said channel and secured against rotation therein;

    rotor means including a plurality of rotor blades operatively disposed within said channel, said rotor blades being axially rotatable about said longitudinal axis and moveable in translation along said longitudingl axis, for substantially occluding and unoccluding said space in response to respective backward and forward differential blood pressures across said rotor means; and

    said stator means and said rotor means being substantially retained within said channel and said rotor blades being restrained from penetrating the plane of said inlet aperture and said outlet aperture in any of said occluded and said unoccluded positions, for providing a low profile valve, the rotation of said rotor means for occluding and unoccluding said space being substantially symmetrical about said longitudinal axis and about at least one axis in a plane normal to said longitudinal axis, said rotor means undergoing equal and opposite angular rotor displacements in the occluding and unoccluding rotational directions, respectively.
