1. A method of deploying a stented prosthetic heart valve to an implantation site, the method comprising the steps of;

  • receiving a delivery system on which an expandable prosthetic heart valve is provided in a first compressed arrangement within a capsule of the delivery system;

    wherein the delivery system further includes a recapture assembly that is longitudinally spaced apart from the prosthetic heart valve at a position proximal to the prosthetic heart valve when the prosthetic heart valve is in the first compressed arrangement;

    wherein the recapture assembly includes a recapture frame and a sleeve;

    further wherein the recapture frame includes a wire frame formed of a shape memory material;

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

    retracting the capsule to allow the prosthetic heart valve to partially expand at the implantation site; and

    distally advancing the recapture assembly relative to the prosthetic heart valve such that the prosthetic heart valve transitions to a second compressed arrangement within the recapture assembly.
