Abstract
Abstract A medical apparatus and method suitable for remodeling a mitral valve annulus adjacent to the coronary sinus. The apparatus comprises an elongate body having a proximal region and a distal region. Each of the proximal and distal regions is dimensioned to reside completely within the vascular system. The elongate body may be moved from a first configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus proximate the coronary sinus. A forming element may be attached to the elongate body for manipulating the elongate body from the first transluminal configuration to the second remodeling configuration. Further, the elongate body may comprise a tube having a plurality of transverse slots therein.
