Percutaneous tricuspid valve repair devices and methods

A method of tricuspid valve repair comprising:

• anchoring a first ventricular surface anchor near an anterior portion of a tricuspid annulus, wherein the first ventricular surface anchor is connected to a first tension member;
• anchoring a second ventricular surface anchor near a right ventricular surface of a posterior portion of the tricuspid annulus, wherein the second ventricular surface anchor is connected to a second tension member;
• anchoring a first tension anchor against a left atrial surface of an interatrial septum, wherein the first tension anchor is connected to a third tension member;
• extending the first tension member connected to the first ventricular surface anchor and the second tension member connected to the second ventricular surface anchor towards the third tension member connected to the first tension anchor;
• and
• with the first tension member, the second tension member, and the third tension member, drawing the anterior portion of the tricuspid annulus and the posterior portion of the tricuspid annulus toward the first tension anchor.

A tricuspid valve repair system comprising:

• two or more surface anchor systems, each surface anchor system comprising:
• a surface anchor comprising a nitinol wire frame defined at its perimeter by a nitinol wire, and comprising an internal nitinol wire feature within an area defined by a perimeter formed by the nitinol wire frame;
• wherein the nitinol wire frame comprises an austenite state in a deployed configuration when a temperature of the nitinol wire frame is body temperature;
• a tether assembly comprising a plurality of tethers, wherein a tether extends from each of the two or more surface anchor systems and connects at a tether connection point;
• and
• a tether lock advanced over the tether connection point, the tether lock configured to limit relative movement between the two or more surface anchor systems.
