Valve prosthesis having a radially-expandable sleeve integrated thereon for delivery and prevention of paravalvular leakage
First Claim
1. A delivery system for percutaneously delivering a self-expanding valve prosthesis comprising:
- an elongated shaft component;
a self-expanding valve prosthesis disposed over a distal portion of the elongated shaft component, wherein the valve prosthesis has a compressed configuration for delivery within a vasculature and an expanded configuration for deployment;
at least one cinching suture for coupling the valve prosthesis to the elongated shaft component, wherein the at least one cinching suture is removable and radially compresses the valve prosthesis into the compressed configuration for delivery; and
a radially-expandable sleeve secured to and encircling an outer surface of the valve prosthesis, wherein the radially-expandable sleeve is configured to transform from a delivery state in which the radially-expandable sleeve has a first diameter and extends over a full length of the valve prosthesis in the compressed configuration to a deployed state in which the radially-expandable sleeve has a second diameter greater than the first diameter and extends over a portion of the valve prosthesis in the expanded configuration, the portion being less than the full length of the valve prosthesis, the radially-expandable sleeve being configured to prevent paravalvular leakage in situ in the deployed state.

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.
