1. A method of minimally-invasively treating mitral valve regurgitation, comprising:

  • advancing an intraluminal cardiac device in a collapsed configuration through a delivery device into a coronary sinus, the intraluminal cardiac device comprising a distal expandable anchor, a proximal expandable anchor, and a connecting member extending between the distal and proximal expandable anchors;

    expanding the distal expandable anchor and anchoring the expanded distal expandable anchor against movement in the coronary sinus at a location proximal to a crossover location of the coronary sinus and a coronary artery so as to avoid occluding blood flow in the coronary artery;

    expanding the proximal expandable anchor and anchoring the proximal expandable anchor against movement in the coronary sinus; and

    pulling proximally on the intraluminal cardiac device to change the geometry of the mitral valve annulus, bringing the leaflets of the mitral valve closer together, thereby reducing undesirable blood flow regurgitation of the mitral valve during the heart cycle.
