<p>Apparatus for reducing mitral regurgitation, including a bendable elongated body (50) adapted to be inserted into the coronary sinus (30) of a patient in the vicinity of the posterior leaflet (39) of the mitral valve (36), the elongated body (50) being adjustable between a first configuration adapted to be delivered into the coronary sinus (30) and a second configuration adapted to exert a force onto the posterior annulus (33). The body (50) includes a flexible spine having a proximal end and a distal end (52), and a flexible wire (54) mounted on the spine and having a distal end fixed to the spine proximate to the distal end of the spine, and having a proximal portion (56) extending from the proximal end of the spine. Axial movement of the wire (54) causes a change in the spine from the first configuration to the second configuration to exert the force on the posterior annulus (33) and thereby reduce mitral regurgitation.</p> |
