摘要：
A delivery system (50) for percutaneously delivering and deploying a stented prosthetic heart valve (20). The delivery device includes a delivery sheath (52) slidably disposed over an inner shaft (54), and a capture assembly (56). The capture assembly includes a spindle (100) and a biasing member (102). The spindle is attached to the inner shaft and defines slot (130). The biasing member is disposed within the slot and self - transitions from a deflected condition to a normal condition. In a delivery state, the delivery sheath retains the prosthesis over the inner shaft and coupled to the spindle via the capture slot, including a portion of the prosthetic valve being engaged within the slot and the biasing member forced to the deflected condition. In a deployment state, the delivery sheath is proximally withdrawn and the biasing member self - transitions toward the normal condition to eject the prosthetic valve from the capture slot.
