Abstract
A delivery system for percutaneously deploying a stented prosthetic heart valve. The system includes a delivery capsule and a recapture assembly. The capsule is configured to compressively retain the prosthesis. The recapture assembly includes a frame and sleeve attached to the frame. The recapture assembly is transitionable from a compressed arrangement to an expanded arrangement with a distally increasing diameter.

25. 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; 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. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. 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 stent 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 system, and a recapture assembly including a recapture frame and sleeve slidably disposed over the inner shaft assembly, the recapture assembly being longitudinally spaced from the prosthetic heart valve in the loaded state; 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 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 capsule, 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 recapture assembly relative to the prosthetic heart valve such that the recapture assembly is distal the capsule and expands to an expanded arrangement having a distally increasing diameter; distally advancing the frame over the prosthetic heart valve; arranging the recapture assembly over the prosthetic heart valve to cause the distal region of the prosthetic heart valve to transition toward the collapsed arrangement within the recapture assembly; and fully proximally retracting the recapture assembly from the prosthetic heart valve such that the prosthetic heart valve self-deploys from the inner shaft assembly. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44)
