Stent for arterialization of the coronary sinus and retrograde perfusion of the myocardium

a technology of retrograde perfusion and coronary sinus, which is applied in the field of stents, can solve the problems of teaching how to construct such a valve, requiring open heart surgery, and invasive methods, and achieves the effects of reducing a significant amount of left-to-right shunt, avoiding damage to the venous system, and increasing pressur

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 or near the trailing (right ventricular) end and at or near 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 hear and specifically the myocardium of the left ventricle and to reduce a significant left-to-right shunt.

Description

[0001] This application is a continuation-in-part of copending application Ser. No. 09 / 796,528, filed Mar. 2, 2001.

[0002] 1. Field of Invention

[0003] The present invention relates to a stent for supplying oxygenated blood retrogradely to the myocardium via the coronary sinus. The stent directs blood from the left ventricle to the coronary sinus through a hole punctured through the wall of the coronary sinus and the wall of the left ventricle and restricting the outflow of the coronary sinus directs that blood retrogradely.

[0004] 2. Description of Related Technology

[0005] Retrograde perfusion using the coronary sinus has long been known for treating end-stage heart disease. Previous methods among others attempted to connect the aorta to the coronary sinus using a jugular vein or an internal mammary artery graft. These methods were invasive in nature and required open heart surgery.
