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 delivery apparatus for a medical device can include a handle, a shaft, a plurality of sleeves, and a suture. The shaft includes a proximal end portion coupled to the handle and is configured to be disposed outside of a patient's body during an implantation procedure and a distal end portion configured to be disposed inside a patient's body during the implantation procedure. Each of the sleeves includes a connection portion coupled to the distal end portion of the shaft and a receiving portion configured to receive an apex of a stent or a prosthetic heart valve. The suture extends through the shaft and the sleeves and is configured for releasably securing the stent or the prosthetic heart valve to the receiving portions of the sleeves.

Abstract: A method for delivering a prosthetic valve to a native annulus of a heart can include inserting a delivery apparatus into a patient's body, advancing the delivery apparatus to an implantation location within the native annulus, retracting a delivery sheath of the delivery apparatus relative to the prosthetic valve to expose the prosthetic valve from a distal end of the delivery sheath, and after the prosthetic valve is exposed from the delivery sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by reducing axial tension on a first end and a second end of the prosthetic valve.

Abstract: A delivery apparatus for a prosthetic implant can include an elongate first shaft, a first suture guide coupled to the first shaft, an elongate second shaft, and a second suture guide coupled to the second shaft. The first shaft can extend coaxially through the second shaft and the second suture guide, the first suture guide can be disposed distal to the second suture guide, and the first suture guide and the second suture guide can be configured to be axially movable relative to each other.
