Abstract

A method and implantation tools for repairing a heart include a delivery catheter and implant. The method includes gaining access to the patient'"'"'s heart and identifying implantation points for the implant. The method may include marking those locations and delivering implant, which may be a tension member. Anchors for the implant may also be delivered. The length of the tension member may be measured and the walls of the heart drawn together. Pads may be secured to the tension member and the tension member trimmed to length. The pads may be secured to the heart surface.

Claims

1. A method for treating a heart of a patient, comprising:

forming an incision in an artery leading to an aorta of the patient;

advancing a delivery catheter through the incision, through the aorta, and through the aortic valve, wherein a distal end of the delivery catheter is positioned in the left ventricle;

implanting a device for treating the heart from the delivery catheter into tissue of the heart; and

withdrawing the delivery catheter from the patient.

2. The method of claim 1, wherein the device comprises a tensile member having opposing ends, implanting the device comprises implanting the opposing ends into heart tissue at two separate locations within the heart.

3. The method of claim 2, wherein the method further comprises:

exerting tension on said tensile member to draw the separate locations within the heart towards one another.

4. The method of claim 3, wherein the heart tissue is ventricular tissue.

5. The method of claim 1, wherein the artery is a femoral artery.

6. The method of claim 1, wherein the artery is a carotid artery.
