1. A delivery system for deploying and recapturing a prosthetic heart valve, the delivery system comprising:
an inner shaft assembly comprising a distal portion and a proximal portion, the inner shaft assembly disposed along an elongated axis, wherein a distal direction of the elongated axis extends from the proximal portion to the distal portion and a proximal direction of the elongated axis extends from the distal portion to the proximal portion;
a delivery sheath assembly comprising a distal portion comprising a distal end and a proximal portion comprising a proximal end, the delivery sheath assembly disposed along the elongated axis, wherein the distal direction of the elongated axis extends from the proximal end to the distal end, the inner shaft assembly slidably received within an interior passage of the proximal portion of the delivery sheath assembly, the distal portion of the delivery sheath assembly comprising a delivery sheath configured to contain a radially expandable prosthetic heart valve in a compressed and collapsed arrangement over the distal portion of the inner shaft assembly, and an inner surface defining the interior passage of the proximal portion of the delivery sheath assembly faces an outer surface of the inner shaft assembly and comprises an unobstructed view of the outer surface of the inner shaft assembly;
a first actuator coupled to the delivery sheath assembly, the first actuator operable to proximally retract the delivery sheath relative to the inner shaft assembly in the proximal direction to expose a distal region of the prosthetic heart valve to allow the distal region to self-expand toward a deployed arrangement;
an outer sheath slidably disposed over the delivery sheath; and
a second actuator coupled to the outer sheath, the second actuator operable to distally advance the outer sheath relative to the delivery sheath in the distal direction to apply a distal force in the distal direction to the expanded distal region of the prosthetic heart valve to facilitate collapse of the expanded distal region of the prosthetic heart valve to be recaptured into the delivery sheath.
