Claim 14:
15. A system for replacing a heart valve of a patient, the system comprising:
a delivery device including:
a first tube assembly comprising a nose piece attached to a distal end of a distal end portion of an inner tube;
a primary capsule configured to be disposed over the distal end portion of the inner tube in a loaded state of the delivery device;
a secondary capsule is configured to be disposed within the primary capsule and over the distal end portion of the inner tube in the loaded state; and

a prosthetic heart valve comprising a stent frame and a valve structure attached to the stent frame, wherein the prosthetic heart valve is configured to circumscribe the distal end portion of the inner tube while being compressively retained within the secondary capsule and the primary capsule in the loaded state,
wherein the primary capsule is configured to be proximally retracted relative to the secondary capsule and the first tube assembly to a partially deployed state of the delivery device where at least a portion of the secondary capsule is radially expanded outside a distal end of the primary capsule, wherein the valve structure of the prosthetic heart valve is configured to open and close in concert with a heartbeat in the partially deployed state, and wherein the secondary capsule is configured to be proximally retracted relative to the first tube assembly from the partially deployed state to a fully deployed state of the delivery device.
