摘要： A delivery system for percutaneously delivering and deploying a stented prosthetic heart valve. The delivery device includes a delivery sheath slidably disposed over an inner shaft, and a capture assembly. The capture assembly includes a spindle and a biasing member. The spindle is attached to the inner shaft and defines slot. 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 In a deployment state, the delivery sheath is proximally withdrawn and the biasing member self-transitions toward the normal condition to eject the prosthetic valve from the capture slot.
