1. A system for transcatheter implantation of a heart valve prosthesis comprising:

  • an outer sheath component defining a lumen therethrough;

    an elongate tube defining a lumen and having at least two wires longitudinally extending from a distal end thereof, the elongate tube and the at least two wires being slidably disposed within the lumen of the outer sheath component;

    an inner shaft slidably disposed within the lumen of the elongate tube;

    a valve prosthesis having a valve frame that is self-expanding with a prosthetic valve component secured therein; and

    a docking frame that is self-expanding, wherein the docking frame is disposed distal of the valve prosthesis when each is held in a compressed delivery configuration within a distal portion of the outer sheath component,wherein in the compressed delivery configuration the valve frame is releasably coupled to a distal end of the inner shaft to be slidable therewith relative to the elongate tube and the at least two wires longitudinally extend along exterior portions of the valve frame and the docking frame and are woven through adjacent distal and proximal ends of the valve frame and the docking frame, respectively, to releasably couple them to each other.
