Abstract: A delivery system includes an elongated shaft component, a self-expanding valve prosthesis, at least one cinching suture, and a radially-expandable sleeve. The valve prosthesis is disposed over a distal portion of the elongated shaft component and includes a compressed configuration for delivery and an expanded configuration for deployment. The at least one cinching suture removably couples the valve prosthesis to the elongated shaft component and radially compresses the valve prosthesis into the compressed configuration for delivery. The sleeve is secured to and encircles an outer surface of the valve prosthesis. The sleeve has a delivery state with a first diameter extending over a full length of the valve prosthesis in the compressed configuration and a deployed state with a greater second diameter extending over the full length of the valve prosthesis in the expanded configuration. The sleeve is configured to prevent paravalvular leakage in situ in the deployed state.

Abstract: A delivery system for a prosthetic valve device includes a first shaft including an outflow capture device mounted on a distal end thereof, a second shaft slidingly disposed over the first shaft and including an inflow capture device mounted on a distal end thereof, and a retractable sheath slidingly disposed over the second shaft to hold the prosthetic valve device in a radially compressed configuration for delivery to a body lumen. The inflow capture device is configured for releasable engagement through openings in a plurality of first attachment members on the device. The outflow capture device is configured for releasable engagement through openings in a plurality of second attachment members on the device.
