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.
Claims25
A method for treating a heart having a zone of infarcted tissue in a chamber thereof, comprising the steps of:
- providing a tension member having a first end and a second end, each of said ends provided with an anchor member;
- and
- positioning said tension member transverse to said chamber to reduce the radius of curvature of a wall of the chamber that includes the infarcted tissue.
A method for treating a heart having a zone of infarcted tissue in a chamber thereof, comprising the steps of:
- positioning a tension member having a first end and a second end, each of said ends provided with an anchor member;
- and
- positioning said tension member transverse to said chamber to draw walls containing the infarcted tissue together.
A method of treating a heart having a zone of infarcted tissue in a chamber thereof, comprising the steps of:
- providing a tension member having a first end and a second end, each of said ends provided with an anchor member;
- positioning one of said anchor members on an outer wall of the infarcted tissue;
- and
- positioning said tension member through the heart chamber such that the infarcted tissue is drawn toward an interior of the heart chamber.
A method of treating a heart having a zone of infarcted tissue in a chamber thereof, comprising the steps of:
- removing the infarcted tissue;
- suturing the chamber wall separated as a result of said removing step;
- providing a tension member having a first end and a second end, each of said ends provided with an anchor member;
- and
- positioning said tension member transverse to said chamber to reduce a radius of curvature of the chamber wall proximal to the suturing.
A method for treating a heart having a zone of infarcted tissue in a chamber thereof, comprising the steps of:
- deforming a wall of the chamber that includes the infarcted tissue such that a radius of curvature of the wall is reduced.
