Patent ID: 8252039

Claim:
A method of treating aortic root dissection in a patient having an ascending aorta in need of such treatment, wherein the ascending aorta has a valve, the method comprises the steps of: providing a resilient tubular support sleeve comprising longitudinal mating edges, a proximal part having a proximal part thickness, a distal part having a distal part thickness, and a base or a flange having a thickness greater than the proximal part thickness and the distal part thickness; wherein the resilient tubular support sleeve is pre-formed with a size shape that morphologically matches the morphological profile and contour of the ascending aorta; locating the resilient tubular support sleeve around the ascending aorta; securing the logitudinal mating edges; and attaching the base or the flange to ventricle muscle, thereby, reinforces or reinstates valve seat to prevent valve leakage.
