Abstract
Apparatus and methods are provided for use with a mitral valve of a heart of a subject. The apparatus includes a P1-anchor, a P2-anchor, and a P3-anchor, that are anchored to tissue in a vicinity of, respectively, P1, P2 and P3 segments of a posterior leaflet of the mitral valve, a tether being fixedly coupled to the P2-anchor, and slidably coupled to the P1 and P3 anchors. A cardiac-site anchor anchors the tether to an anchoring location that is at a cardiac site that is anterior and inferior to the posterior leaflet. Other embodiments are also described.
Claims21
1-35. (canceled)
36:
- A heart valve device comprising:
- a first anchor configured to be anchored to tissue at a first vicinity of a valve annulus of a heart;
- a second anchor configured to be anchored to tissue at a second vicinity of the valve annulus of the heart;
- a third anchor configured to be anchored to tissue at a vicinity of an apex of the heart;
- and
- a tether coupled to the first, second, and third anchors, wherein a first segment of the tether slidably extends through the first anchor and through the third anchor and a second segment of the tether slidably extends through the second anchor and through the third anchor, wherein the first and second segments of the tether are configured to be tensioned toward the third anchor following anchoring of the first, second, and third anchors, the third anchor configured to secure the first and second segments of the tether in a tensioned state.
