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.

Abstract
A delivery system for percutaneously deploying a prosthetic heart valve. The system includes an inner shaft assembly, a delivery sheath capsule and a handle maintaining a first actuator and a second actuator. The capsule is configured to compressively retain the prosthetic heart valve over the inner shaft assembly. The first actuator is operated to proximally retract the delivery sheath capsule and expose the prosthetic heart valve relative to the capsule. The second actuator is operated to proximally retract the prosthetic heart valve by transmitting forces to the inner shaft assembly.

7. A device for repairing a heart valve of a patient, the device comprising:
-
a delivery system including; an inner shaft assembly including an intermediate portion providing a coupling structure, 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, a handle coupled to the inner shaft assembly, and the delivery sheath assembly, the handle maintaining a first actuator coupled to the delivery sheath assembly and a second actuator coupled to the inner shaft assembly; and a prosthetic heart valve having a frame and a valve structure attached to the frame and forming at least two valve leaflets, the prosthetic heart valve being self-expandable from a compressed arrangement to a natural arrangement; wherein the device is configured to be transitionable between; a loaded state in which the prosthetic heart valve engages the coupling structure and is compressively retained within the capsule, a partially deployed state in which the capsule is at least partially withdrawn from the prosthetic heart valve upon operation of the first actuator such that a distal region of the prosthetic heart valve is exposed relative to the capsule and self-expands, and a recapturing state in which the prosthetic heart valve is retracted into the delivery system upon simultaneous operation of the second actuator to a distance away from the handle to transmit proximal forces to the prosthetic heart valve and of the first actuator between a proximal end and a distal end of the handle to apply distal forces to the delivery sheath capsule. - View Dependent Claims (8, 9, 10)
