Abstract

A method and implantation tools for placing a transventricular splint including a tension member. The method includes gaining access to the patient'"'"'s hearts and identifying entry or exit points for the tension member, marking those locations and delivering the tension member. Anchors for the tension member are also delivered. The length of the tensions member is measured and the walls of the heart drawn together. The pads are secured to the tension member and the tension member is trimmed to length. The pads are secured to the heart surface.

Claims

1. A method of implanting a transventricular splint having an elongate tension member and two oppositely disposed anchors, comprising the steps of:

selecting the location on the ventricle for placement of the splint;

advancing a first tension member through a first side of the ventricle;

advancing a second tension member through a second side of the ventricle;

deploying an anchor on each tension member; and

connecting the tension members.

2. The method in accordance with

claim 1

, wherein the tension members are connected within the heart.

3. The method in accordance with

claim 1

, wherein the first tension member is advanced into the heart from the first side.

4. The method in accordance with

claim 3

, wherein the second tension member is advanced into the heart from the second side.

5. The method in accordance with

claim 1

, wherein the first tension member is advanced into the heart proximate the apex.

6. The method in accordance with

claim 5

, wherein the first tension member is then advanced through the first side.

7. The method in accordance with

claim 5

, wherein the second tension member is advanced into the heart proximate the apex.

8. The method in accordance with

claim 7

, wherein the second tension member is then advanced through the second side.
