Examples of an apparatus, system and method for changing a geometry of a mitral valve of a heart are described herein. In one example embodiment, the apparatus comprises an anchor having a body for positioning and anchoring within a coronary sinus vein of the heart. The body has a first end and a second end that is spaced apart from the first end； a longitudinally extending axis； and a wall with an interior volume extending between the first and second ends, the interior volume being adapted for receiving a steerable catheter. The apparatus also includes a first link member having a proximal end nearest to the anchor and a distal end spaced apart from the proximal end. The proximal end of the first link member is coupled to the anchor by a joint configured to provide for movement of the first link member in one direction relative to the anchor.
