1. An implant for supplementing, repairing, or replacing a native heart valve having an annulus and a leaflet or leaflets comprising:

  • a scaffold, at least a portion of the scaffold defining a pseudo-annulus, said pseudo-annulus having a circumference, the scaffold movable between an undeformed configuration and an elastically deformed condition by the application of external compressive force;

    the implant further comprising at least two struts, said struts in generally oppositely spaced apart positions along the circumference of the pseudo-annulus and depending downwardly below the plane of the pseudo-annulus, said struts biased away from each other when said scaffold is placed in said elastically deformed condition wherein when said scaffold is in said elastically deformed condition the struts may be placed in said valve with said pseudo-annulus adjacent said annulus to urge said annulus in an outward direction;

    the implant further comprising a neoleaflet element, said neoleaflet element comprising;

    a bridge supported by the scaffold, said bridge overlaying less than the full diameter of the pseudo-annulus when said scaffold is in said undeformed configuration; and

    a spanning material covering said bridge,said neoleaflet element being located within the pseudo-annulus when said scaffold is in said undeformed configuration in a manner that will, alone or in conjunction with the native leaflets, allow fluid to flow through the pseudo-annulus in one direction, but obstruct fluid flow in the opposite direction to provide, alone or in conjunction with one or more native leaflets, a one-way valve function within the annulus.
