1. A method of recapturing a deployed stented prosthetic heart valve at an implantation site, the method comprising:

  • receiving a delivery system loaded with a radially expandable prosthetic heart valve having a frame to which a valve structure is attached, the delivery system comprising an outer sheath over an inner sheath, the inner sheath containing the prosthetic heart valve in a compressed arrangement over an inner shaft assembly in a loaded state of the delivery system;

    delivering the prosthetic heart valve in the compressed arrangement through a bodily lumen of a patient and to the implantation site via the delivery system in the loaded state;

    proximally retracting the inner sheath relative to the prosthetic heart valve such that a distal region of the prosthetic heart valve is exposed distal the inner sheath, wherein the distal region self-expands toward a deployed arrangement;

    evaluating a position of the prosthetic heart valve relative to the implantation site;

    distally advancing the outer sheath relative to the prosthetic heart valve such that the outer sheath is arranged over the prosthetic heart valve to cause the distal region of the prosthetic heart valve to transition toward a collapsed arrangement to recapture the prosthetic heart valve within the outer sheath, andproximally advancing the inner shaft assembly simultaneously with distally advancing the outer sheath to position the outer sheath over the distal region of the prosthetic heart valve to transition toward the collapsed arrangement to recapture the prosthetic heart valve within the outer sheath.
