Claim Text:
1. A delivery device for percutaneously deploying a stented prosthetic heart valve including a stent frame to which a valve structure is attached, the device comprising: a delivery sheath assembly terminating at a distal end and defining a lumen; an inner shaft slidably disposed within the lumen; and a capture assembly for selectively coupling the stented prosthetic heart valve relative to the inner shaft, the capture assembly comprising: wherein the delivery device is configured to provide: a delivery state in which the delivery sheath assembly retains the stented prosthetic heart valve over the inner shaft and the biasing member in the deflected condition, including a portion of the stented prosthetic heart valve engaged with the at least one coupling section and the biasing member forced to the deflected condition; and a deployment state in which the distal end of the delivery sheath assembly is withdrawn from covering at least a portion of the capture assembly, wherein the biasing member transitions to the normal condition such that the free end rotates about the fixed end to radially deflect the stent frame, and wherein the biasing member further includes an intermediate region positioned between the free end and the fixed end, wherein the intermediate region projects radially to a greater distance from the centerline than the fixed end in the normal and deflected conditions.
