Problems solved by technology

Unfortunately, however, patients with acute mitral regurgitation complicated by acute myocardial infarction are particularly high-risk surgical candidates and are therefore not candidates for traditional annuloplasty procedures

Embodiment Construction

[0090] Overview

[0091] In the human heart, the coronary sinus is the largest vein. The coronary sinus typically extends adjacent to the left atrium of the heart at a distance of approximately 5 to 10 centimeters during most of its travel within the atrioventricular groove. Notably, the coronary sinus extends substantially adjacent to the posterior perimeter of the mitral valve annulus for a portion of its length such as typically approximately 7-9 centimeters. The present invention takes advantage of this fact. More specifically, by deploying a novel device within the coronary sinus adjacent to the posterior leaflet of the mitral valve, the natural curvature of the coronary sinus can be altered, thereby moving the posterior annulus anteriorly, thereby improving leaflet closure , thereby reducing mitral regurgitation.

Abstract

A method and apparatus for reducing mitral regurgitation. The apparatus is inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the apparatus being adapted to straighten the natural curvature of at least a portion of the coronary sinus in the vicinity of the posterior leaflet of the mitral valve, whereby to move the posterior annulus anteriorly and thereby improve leaflet coaptation and reduce mitral regurgitation.
