1. A delivery system for percutaneously deploying a stented prosthetic heart valve, the system comprising:

  • an inner shaft assembly including an intermediate portion providing a coupling structure configured to selectively engage a prosthetic heart valve;

    a delivery sheath assembly slidably disposed over the inner shaft assembly, the delivery sheath assembly including a tubular capsule and a delivery shaft, wherein the capsule extends from a distal end of the delivery shaft and is configured to compressively contain a prosthetic heart valve engaged with the coupling structure; and

    a handle coupled to the inner shaft assembly and the delivery sheath assembly, the handle including a housing having a proximal end and a distal end, the handle maintaining a first actuator selectively applying forces to the delivery sheath assembly and a second actuator selectively applying forces to the inner shaft assembly to retract the prosthetic heart valve, the first actuator and the second actuator being operated simultaneously relative to the handle to apply forces to the delivery sheath assembly and the inner shaft assembly so as to promote recapture of the prosthetic heart valve within the capsule, the first actuator is positioned between the proximal end and the distal end and includes a user interface slidably retained by the housing, the user interface at least partially and slidably extending within a slotted opening to outside of the housing, wherein the first actuator is operated toward the distal end to apply distal forces to the delivery sheath capsule, the second actuator is positioned at the proximal end, wherein the second actuator is operated away from the proximal end in a spaced apart relationship from the proximal end to apply proximal forces to the prosthetic heart valve.
