1. A method for treating a heart, the heart having a first chamber bordered by a septum and a wall, wherein the chamber comprises a left ventricle of the heart, the heart having a second chamber separated from the first chamber by the septum, the method comprising:
- penetrating the septum at a first location;
penetrating the wall at a second location;
penetrating the wall at a third location that is laterally offset from the second location;
affixing a first anchor adjacent the penetration of the septum;
affixing a second anchor adjacent the penetration of the wall at the second location, wherein a first tension member extends from the first anchor to the second anchor and tensionalby couples the first anchor and the second anchor;
affixing a third anchor adjacent the penetration of the wall at the third location, wherein a second tension member extends from the first anchor to the third anchor and tensionalby couples the first anchor and the third anchor such that a plurality of anchors positioned adjacent the wall are tensionably coupled with the first anchor;
applying tension between the first anchor, the second anchor, and the third anchor by tensioning the first tension member and the second tension member so that tension is applied between the septum and the wall;
wherein the first anchor, the second anchor, and the third anchor are tensioned sufficiently to bring the wall and septum into engagement, and wherein the second and third anchors are separated so as to, in combination, extend the engagement across a portion of the wall sufficiently to effectively exclude regions of the wall and septum from the left ventricle with scar tissue extending along the excluded regions.

Abstract
Devices, systems, and methods for treating a heart of a patient may make use of one or more implant structures which limit a size of a chamber of the heart, such as by deploying a tensile member to bring a wall of the heart toward (optionally into contact with) a septum of the heart.

8. A method for treating a heart, the heart having a first chamber bordered by a septum and a wall, wherein the chamber comprises a left ventricle of the heart, the heart having a second chamber separated from the first chamber by the septum, the method comprising:
-
penetrating the septum; penetrating the wall at a first location; penetrating the wall at a second location that is laterally offset from the first location; affixing a septal anchor adjacent the penetration of the septum; affixing a first wall anchor adjacent the penetration of the wall at the first location, wherein a first tension member extends from the septal anchor to the first wall anchor; affixing a second wall anchor adjacent the penetration of the wall at the second location, wherein a second tension member extends from the septal anchor to the second wall anchor; applying tension between the septal anchor and the first and second wall anchors via the first and second tension members to apply tension to the septum and the wall. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for treating a heart, the heart having a first chamber bordered by a first wall and a second wall, the method comprising:
-
penetrating the first wall; penetrating the second wall at a first location; penetrating the second wall at a second location that is laterally offset from the first location; affixing a first anchor adjacent the penetration of the first wall; affixing a second anchor adjacent the penetration of the second wall at the first location; coupling a first tension member with the first anchor and the second anchor, the first tension member being tensionable to apply tension to the first wall and the second wall at the first location via the first anchor and the second anchor; affixing a third anchor adjacent the penetration of the second wall at the second location; and coupling a second tension member with the first anchor and the third anchor, the second tension member being tensionable to apply tension to the first wall and the second wall at the second location via the first anchor and the third anchor. - View Dependent Claims (16, 17, 18, 19, 20)
