Abstract
A method is provided that includes implanting (a) a venous first tissue anchor in a vein selected from the group of veins consisting of: a superior vena cava and an inferior vena cava, (b) an atrial second tissue anchor at an atrial site selected from the group of sites consisting of: an annulus of a tricuspid valve, and a wall of a right atrium of a heart above the annulus of the tricuspid valve, (c) a venous third tissue anchor in a coronary sinus, and (d) one or more tethers, which connect the venous first tissue anchor, the atrial second tissue anchor, and the venous third tissue anchor. A size of a tricuspid orifice is reduced by tensioning the one or more tethers. Other embodiments are also described.
