| 1. A method of treating tissue near a valve to modify flow through the valve, comprising:
advancing a catheter within a coronary sinus around a periphery of the valve;
deploying a plurality of anchor members from the catheter selectively along the periphery and within the coronary sinus, each
of the anchor members being connected sequentially via a tensioning element passed through an opening defined in each member;
and
tightening the tensioning element such that tissue around the periphery of the valve is drawn together.
