| 摘要 |
<p>The present invention concerns a novel stent (101) and a method for communicating oxygenated blood directly from the left ventricle (202) to the coronary sinus (218) to provide retrograde perfusion to the myocardium. The stent (101) is placed substantially within the coronary sinus (218) with its trailing end (109) protruding into the right atrium (210) and the leading end (105) protruding into the left ventricle (202). The stent (101) has a smaller passageway at the trailing (right ventricular) end at the leading (left ventricle) end, and a covering (120) 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.</p> |
