An apparatus, comprising: an outer sheath defining a lumen; a delivery sheath defining a lumen and being movably disposed within the lumen defined by the outer sheath, a prosthetic heart valve disposed within the lumen of the delivery sheath in a collapsed configuration, the prosthetic heart valve including an outer frame coupled to an inner frame, the inner frame being removably coupled to a distal end portion of a valve holder, the outer frame being movable between a first configuration relative to the inner frame and a second configuration relative to the inner frame in which the outer frame is inverted relative to the inner frame, the prosthetic heart valve being disposed within the lumen of the delivery sheath with the outer frame in the second configuration; a first actuation wire releasably coupled to a first portion of the outer frame; and a second actuation wire releasably coupled to a second portion of the outer frame, each of the first actuation wire and the second actuation wire having (i) a first portion extending proximally from the outer frame, through the lumen of the outer sheath, along an outside wall of the delivery sheath, and through a first side aperture defined by the delivery sheath, and (ii) a second portion extending proximally from the outer frame, through the lumen of the outer sheath, along the outside wall of the delivery sheath, and through a second side aperture defined by the delivery sheath, the first portion and the second portion of each of the first actuation wire and the second actuation wire configured to be pulled proximally to urge the outer frame from the second configuration towards the first configuration relative to the inner frame, and an elongate member movably disposed within the lumen of the delivery sheath, end portions of the first actuation wire and the second actuation wire being releasably coupled to a distal end portion of the elongate member. an outer sheath defining a lumen; a delivery sheath defining a lumen and being movably disposed within the lumen defined by the outer sheath, a prosthetic heart valve disposed within the lumen of the delivery sheath in a collapsed configuration, the prosthetic heart valve including an outer frame coupled to an inner frame, the inner frame being removably coupled to a distal end portion of a valve holder, the outer frame being movable between a first configuration relative to the inner frame and a second configuration relative to the inner frame in which the outer frame is inverted relative to the inner frame, the prosthetic heart valve being disposed within the lumen of the delivery sheath with the outer frame in the second configuration; a first actuation wire releasably coupled to a first portion of the outer frame; and a second actuation wire releasably coupled to a second portion of the outer frame, each of the first actuation wire and the second actuation wire having (i) a first portion extending proximally from the outer frame, through the lumen of the outer sheath, along an outside wall of the delivery sheath, and through a first side aperture defined by the delivery sheath, and (ii) a second portion extending proximally from the outer frame, through the lumen of the outer sheath, along the outside wall of the delivery sheath, and through a second side aperture defined by the delivery sheath, the first portion and the second portion of each of the first actuation wire and the second actuation wire configured to be pulled proximally to urge the outer frame from the second configuration towards the first configuration relative to the inner frame, and an elongate member movably disposed within the lumen of the delivery sheath, end portions of the first actuation wire and the second actuation wire being releasably coupled to a distal end portion of the elongate member.
