1. A method of treating a heart valve, the method comprising:
- providing a device having an elongate member, the elongate member having a first end and a second end;
positioning the elongate member transverse a heart chamber associated with the heart valve so as to reposition at least one leaflet associated with the heart valve,wherein, when the elongate member is positioned transverse the heart chamber, the elongate member does not contact each of papillary muscles, leaflets, and an annulus associated with the heart valve; and
wherein the entire device is positioned solely above an apex of the heart and below an annulus associated with the heart valve.

Abstract
Various methods and devices are disclosed for improving cardiac function in hearts having zones of infarcted (akinetic) and aneurysmal (dyskinetic) tissue regions. The methods and devices reduce the radius of curvature in walls of the heart proximal infarcted and aneurysmal regions to reduce wall stress and improve pumping efficiency. The inventive methods and related devices include splinting of the chamber wall proximal the infarcted region and various other devices and methods including suture and patch techniques.

12. A method of treating a heart valve, the method comprising:
-
providing a device configured to be implanted proximate the heart valve; implanting the device such that a first portion of the device is positioned external to a heart chamber associated with the valve and closer to a first leaflet of the valve than to a second leaflet of the valve and such that a second portion of the device is positioned external to the heart chamber associated with the valve and closer to the second leaflet of the valve than the first leaflet of the valve; and repositioning at least one of the first leaflet and the second leaflet of the valve, wherein, when the device is implanted, the device does not contact each of papillary muscles, leaflets, and an annulus associated with the valve, and wherein the entire device is implanted solely above an apex of the heart and below an annulus associated with the heart valve. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method of treating a heart valve having a first leaflet and a second leaflet, the method comprising:
-
providing a device configured to be implanted proximate the heart valve; implanting the device such that a first portion of the device contacts heart structure located on a first side of a line defined by an intersection of the first leaflet and the second leaflet and such that a second portion of the device contacts heart structure located on a second side of the line opposite the first side; and repositioning at least one of the first leaflet and the second leaflet of the valve, wherein, when the device is implanted, the device does not contact each of papillary muscles, lealflets, and an annulus associated with the valve, and wherein the entire device is implanted solely above an apex of the heart and below an annulus associated with the heart valve. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
