Abstract
A method and apparatus for treating mitral regurgitation by approximating the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve. The distal end of the device is inserted into the coronary sinus of the heart and the proximal end of the device rests within the right atrium along the tendon of Todaro and extends to at least the membranous septum of the tricuspid valve. Because the coronary sinus approximates the lateral (posterior) annulus of the mitral valve and the tendon of Todaro approximates the septal (anterior) annulus of the mitral valve, the device encircles approximately one half of the mitral valve annulus. The apparatus is then adapted to deform the underlying structures i.e. the septal annulus and lateral annulus of the mitral valve in order to move the posterior leaflet anteriorly and the anterior leaflet posteriorly and thereby improve leaflet coaptation and eliminate mitral regurgitation.
