Apparatus and method for reducing mitral regurgitation
First Claim
1. Apparatus for reducing mitral regurgitation, the apparatus comprising:
- a bendable elongated body adapted to be inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the elongated body being adjustable between a first configuration adapted to be delivered into the coronary sinus and a second configuration adapted to exert a force onto the posterior annulus, the body comprising;
a flexible spine having a proximal end and a distal end, said flexible spine forming a longitudinal axis from said proximal end to said distal end, a plurality of wire supporting portions extending transversely from said spine, each said portion defining a channel therethrough, said plurality of wire supporting portions defining a plurality of openings therebetween, and a plurality of flexible bridges connecting said plurality of wire supporting portions to one another; and
a flexible wire slideably mounted through said plurality of wire supporting portions extending from said spine and having a distal end fixed to said spine proximate to the distal end of said spine, and having a proximal portion extending from the proximal end of said spine;
whereby axial movement of said wire causes a change in said spine from the first configuration to the second configuration to exert the force on the posterior annulus and thereby reduce mitral regurgitation.

Abstract
Apparatus for reducing mitral regurgitation, including a bendable elongated body adapted to be inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the elongated body being adjustable between a first configuration adapted to be delivered into the coronary sinus and a second configuration adapted to exert a force onto the posterior annulus. The body includes a flexible spine having a proximal end and a distal end, and a flexible wire 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 extending from the proximal end of the spine. Axial movement of the wire causes a change in the spine from the first configuration to the second configuration to exert the force on the posterior annulus and thereby reduce mitral regurgitation.
