Tissue shaping device

A method of orienting an intraluminal cardiac device within the coronary sinus for the treatment of mitral valve regurgitation, the method comprising:

• advancing an intraluminal cardiac device in a collapsed configuration into a coronary sinus, the intraluminal cardiac device comprising a first expandable anchor, a second expandable anchor, and a connecting member extending between the first and second expandable anchors, the connecting member predisposed with a curved configuration;
• expanding the first expandable anchor within the coronary sinus;
• anchoring the first expandable anchor against movement in the coronary sinus;
• deploying the connecting member such that at least a portion of the curved configuration of the connecting member generally corresponds to the curved shape of the coronary sinus and such that the connecting member is disposed on the inside curve of the coronary sinus;
• pulling proximally on the intraluminal cardiac device so as to change the geometry of the mitral valve annulus and bring the leaflets of the mitral valve closer together, thereby reducing undesirable blood flow regurgitation back through the mitral valve during the heart cycle;
• expanding the second expandable anchor within the coronary sinus;
• and
• anchoring the second expandable anchor against movement in the coronary sinus after the pulling step,
• wherein expanding the first expandable anchor comprises moving an apex of the first expandable anchor, relative to the connecting member, radially outward and away from the connecting member and away from the inside curve of the coronary sinus.
