Multiple anchoring-point tension system
First Claim
1. A method comprising:
- implanting;
a first venous tissue anchor in a vein selected from the group of veins consisting of;
a superior vena cava, an inferior vena cava, and a coronary sinus,exactly two atrial tissue anchors, which consist of second and third atrial tissue anchors, at respective different atrial sites, each of which sites is 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, anda pulley system, which includes (a) a pulley, which is connected to the second atrial tissue anchor, and (b) a tether, which (i) is connected to the first venous tissue anchor and the third atrial tissue anchor, (ii) is moveable through the pulley, and (iii) has a length, measured between the first venous and the third atrial tissue anchors, of at least 30 mm; and
reducing a size of a tricuspid orifice by tensioning the tether.

Abstract
A method is provided that includes implanting (a) a first venous tissue anchor in a superior vena cava, an inferior vena cava, or a coronary sinus, (b) exactly two atrial tissue anchors, which consist of second and third atrial tissue anchors, at respective different atrial sites, each of which sites is selected from: an annulus of a tricuspid valve, and a wall of a right atrium of a heart above the annulus, and (c) a pulley system, which includes (i) a pulley, which is connected to the second atrial tissue anchor, and (ii) a tether, which (A) is connected to the first venous tissue anchor and the third atrial tissue anchor, (B) is moveable through the pulley, and (C) has a length, measured between the first venous and the third atrial tissue anchors, of at least 30 mm. A size of a tricuspid orifice is reduced by tensioning the tether.
