Abstract: A handle for a prosthetic heart valve delivery apparatus includes a housing, a motorized mechanism, and a holding mechanism. The housing is configured to be hand-held by a user and includes a distal opening. The motorized mechanism is disposed within the housing and is configured to be releasably coupled to a proximal end portion of a first shaft of the prosthetic heart valve delivery apparatus. When actuated, the motorized mechanism is configured to rotate the first shaft relative to the housing. The holding mechanism is disposed inside the housing and is configured to engage a proximal end portion of a second shaft of the prosthetic heart valve delivery apparatus such that the second shaft is axially and rotationally fixed relative to the housing, and the first shaft extends through the second shaft.

Abstract: Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body.

Abstract: A prosthetic heart valve delivery system can include a catheter portion having a sheath that can cover and uncover the prosthetic heart valve mounted on an inner shaft, a handle having a sheath actuator operatively coupled to a proximal portion of the sheath, the inner shaft extending through the handle, and a shaft retractor releasably coupled to a proximal portion of the handle and fixedly coupled to a proximal portion of the inner shaft. A sheath actuator can move the sheath axially relative to the inner shaft when the shaft retractor is coupled to the handle, and a proximal movement of the sheath relative to the inner shaft can cause the sheath to uncover the prosthetic heart valve. The shaft retractor can be operable to retract the inner shaft and the nosecone proximally relative to the sheath when the shaft retractor is released from the handle.
