Abstract

A method of reducing tricuspid valve regurgitation is provided, including implanting first, second, and third tissue anchors at respective different first, second, and third implantation sites in cardiac tissue in the vicinity of the tricuspid valve of the patient. The geometry of the tricuspid valve is altered by drawing the leaflets of the tricuspid valve toward one another by applying tension between the first, the second, and the third tissue anchors by rotating a spool that (a) winds therewithin respective portions of first, second, and third longitudinal members coupled to the first, the second, and the third tissue anchors, respectively, and (b) is suspended along the first, the second, and the third longitudinal members hovering over the tricuspid valve away from the annulus of the tricuspid valve. Other embodiments are also described.
