Claim Text:
1. A method of deploying a stented prosthetic heart valve to 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 including a delivery sheath capsule 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 delivery sheath capsule relative to the prosthetic heart valve such that a distal region of the prosthetic heart valve is exposed distal the delivery sheath capsule, wherein the distal region self-expands toward a deployed arrangement; evaluating a position of the prosthetic heart valve relative to the implantation site; proximally advancing the prosthetic heart valve relative to the delivery sheath capsule by applying proximal forces to the inner shaft assembly such that the delivery sheath capsule is arranged over the prosthetic heart valve to cause the distal region of the prosthetic heart valve to transition toward the collapsed arrangement within the delivery sheath capsule; and fully proximally retracting the delivery sheath capsule from the prosthetic heart valve such that the prosthetic heart valve self-deploys from the inner shaft assembly.
