Cardiac tissue cinching
First Claim
1. A method comprising:
- making an opening through an atrial septum at a septal site at least 5 mm from a fossa ovalis;
endovascularly advancing a first tissue anchor to a left-atrial site selected from the group of sites consisting of;
a mitral annular site on an annulus of a mitral valve, and a wall of a left atrium of a heart above the mitral annular site;
implanting the first tissue anchor at the left-atrial site;
endovascularly advancing a second tissue anchor to a right-atrial site selected from the group of sites consisting of;
a tricuspid annular site on an annulus of a tricuspid valve, and a wall of a right atrium of the heart above the tricuspid annular site;
implanting the second tissue anchor at the right-atrial site; and
reducing the size of the tricuspid valve orifice and the size of the mitral valve orifice by approximating the left-atrial site and the right-atrial site by tensioning a tether that passes through the opening of the atrial septum and connects the first and the second tissue anchors.

Abstract
A method is provided including making an opening (300) through an atrial septum (302) at a septal site (304) at least 5 mm from a fossa ovalis (330). A first tissue anchor (204) is endovascularly advanced to a left-atrial site (306) on an annulus of a mitral valve (310) or a wall of a left atrium (308) above the annulus. The first tissue anchor (204) is implanted at the left-atrial site (306). A second tissue anchor (24) is endovascularly advanced to a right-atrial site (320) on an annulus of a tricuspid valve (207) or a wall of a right atrium (200) above the annulus. The second tissue (24) anchor is implanted at the right-atrial site (320). The left-atrial site (306) and the right-atrial site (320) are approximated by tensioning a tether (22) that passes through the opening (300) of the atrial septum (302) and connects the first and the second tissue anchors (204, 24). Other embodiments are also described.
