Abstract
Abstract The present invention concerns a novel stent and a method for communicating oxygenated blood directly from the left ventricle to the coronary sinus to provide retrograde perfusion to the myocardium. The stent is placed substantially within the coronary sinus with its trailing end protruding into the right atrium and the leading end protruding into the left ventricle. The stent has a smaller passageway at the trailing (right ventricular) end and at the leading (left ventricle) end, and has a covering at the trailing end. The smaller passageway and the cover at the trailing end to promote retrograde flow into the venous system of the heart and specifically the myocardium of the left ventricle and to reduce a significant left-to-right shunt.
