1. A device for delivering a cardiac valve prosthesis to an implantation site, the device comprising:

  • a distal valve holder portion defining a cavity adapted to receive and radially constrain the valve prosthesis therein;

    a shaft coupled to the valve holder portion, the shaft including a tubular sleeve and a core disposed partially within the tubular sleeve, the core adapted to move axially with respect to the sleeve;

    a valve support disposed at or near a distal end of the shaft, the valve support including an annular recess adapted to mate with a portion of the valve prosthesis;

    a deployment mechanism adapted to axially translate the valve support with respect to the distal valve holder, such that the valve prosthesis is selectively deployed at the implantation site; and

    a deflection mechanism coupled to shaft, the deflection mechanism adapted to selectively vary the spatial orientation of the valve holder portion with respect to the implantation site.
