Abstract
An improved dynamic aortic patch is surgically implanted in the thoracic aorta and is systematically inflated and deflated to generate pressure waves in the bloodstream. The pressure waves assist the heart by augmenting the circulation of the blood through the body. The patch includes a flexible inflatable bladder and an independent envelope. The envelope has a reinforced surface for limiting and directing inflation of the bladder inwardly toward the lumen of the aorta.
