Claim Text:
1. A delivery system for percutaneously deploying a stented prosthetic heart valve transitionable between a first arrangement defining a first diameter and a second arrangement defining a second diameter greater than the first diameter, the system comprising: an inner shaft assembly including an intermediate portion providing a coupling structure configured to selectively engage the stented prosthetic heart valve; a delivery sheath capsule slidably disposed over the inner shaft assembly and configured to compressively contain the stented prosthetic heart valve engaged with the coupling structure; and a recapture assembly slidably disposed over the inner shaft assembly, the recapture assembly including a recapture frame and a sleeve coupled to the frame, wherein the frame is transitionable from a compressed arrangement to an expanded arrangement in which the frame has a distally increasing diameter; wherein the system is configured to provide a loaded state in which the capsule compressively retains the stented prosthetic heart valve over the inner shaft assembly and the recapture assembly is longitudinally displaced from the stented prosthetic heart valve and wherein the system is further configured to provide a recapturing state in which a distal region of the stented prosthetic heart valve is distal the capsule and the recapture assembly is slidably disposed over the stented prosthetic heart valve distal the capsule in order to compress the stented prosthetic heart valve to a third arrangement, wherein a maximum diameter of the stented prosthetic heart valve in the third arrangement is greater than the first diameter and less than the second diameter.
