1. A method of delivering a valve prosthesis to a target treatment location comprising:
introducing a delivery system into a patient's vasculature, the delivery system including an elongated shaft component and a valve prosthesis disposed over a distal portion of the elongated shaft component, wherein the valve prosthesis is in a radially compressed configuration and a radially-expandable sleeve is secured to and encircles an outer surface of the valve prosthesis, the radially-expandable sleeve being in a delivery state in which the radially-expandable sleeve has a first diameter;
advancing the delivery system within the patient's vasculature to a target treatment location with the radially-expandable sleeve forming an outermost component of the delivery system for a longitudinal portion thereof;
deploying the valve prosthesis to a radially expanded configuration at the target treatment location, wherein deployment of the valve prosthesis causes the radially-expandable sleeve to transform from the delivery state to a deployed state in which the radially-expandable sleeve has a second diameter greater than the first diameter; and
removing the delivery system from the patient's vasculature while the valve prosthesis and the radially-expandable sleeve remain at the target treatment location, wherein the radially-expandable sleeve in the deployed state is configured to prevent paravalvular leakage.
