Mitral valve annuloplasty ring for molding left ventricle geometry

Abstract From the Canadian patent

An annuloplasty ring for correcting maladies of the mitral annulus that not only reshapes the annulus but also reconfigures the adjacent left ventricular muscle wall. The ring may be continuous and is made of a relatively rigid material, such as Stellite. The ring has a generally oval shape that is threedimensional at least on the posterior side. A posterior portion of the ring rises or bows upward from adjacent sides to pull the posterior aspect of the native annulus farther up than its original healthy shape. In doing so, the , ring also pulls the ventricular wall upward which helps mitigate some of the effects of congestive heart failure. Further one or both of the posterior and , …
