Shaping suture for treating congestive heart failure
A kit and method are described for treating congestive heart failure. The kit may comprise multiple components including a shaping device, deployment tool, patch, and suture. The method may utilize one or more of these components.
1 . A method for treating ischemic congestive heart failure comprising the steps of:
identifying akinetic tissue within a heart chamber wall;
making an incision through the akinetic tissue in the chamber wall;
placing a patch inside the chamber wall;
excluding the akinetic tissue through suturing wherein the suture comprises a superelastic or shape memory material; and
closing the incision.
2 . The method of claim 1 further comprising using a purse-string stitch to exclude the akinetic tissue.
3 . The method of claim 1 , wherein the suture comprises nitinol.
4 . The method of claim 1 , wherein the suture comprises more than one material.
5 . The method of claim 1 , wherein the step of making an incision comprises using an endoscope with an incising tip.
6 . The method of claim 1 further comprising the step of inserting a shaping device into the chamber through the incision, said shaping device comprising compliant material.
7 . The method of claim 1 further comprising the step of inserting a shaping device into the chamber through the incision, said shaping device being self-expanding.
8 . The method of claim 1 , wherein the patch comprises a superelastic or shape memory material.
9 . The method of claim 1 , wherein the patch is configured to engage the ventricle wall to limit the movement of the patch relative to the ventricle wall.
10 . The method of claim 1 , wherein the step of identifying akinetic tissue comprises providing one or more images to a computer.
11 . The method of claim 1 further comprising the steps of providing one or more images to a computer, and using the computer to determine when to perform the method.
12 . The method of claim 11 , wherein images of the heart at different time intervals can be saved.
13 . The method of claim 11 , wherein two or more persons using different computers can view the model.
14 . The method of claim 1 further comprising the steps of providing one or more images to a computer, and using the computer to determine an appropriate size for one or more devices.
15 . The method of claim 1 , wherein the suture comprises three sections such that the section in the middle along the length of the suture comprises a superelastic or shape memory material
16 . A device for closing an opening in anatomical tissue comprising an elongate suture having a plurality of sections wherein at least one of said sections comprises a superelastic or shape memory material.
17 . The device of claim 16 , wherein said suture comprises a synthetic material.
18 . The device of claim 16 , wherein said suture comprises a natural material.
19 . The device of claim 16 , wherein one or more of said sections comprises nitinol.
20 . The device of claim 16 , wherein the suture when drawn around an opening forms a non-circular shape.
21 . A method for treating a heart related ailment in a patient comprising the steps of:
identifying akinetic tissue within a heart chamber wall;
making an incision through the akinetic tissue in the chamber wall;
placing one or more patches inside the chamber wall;
excluding the akinetic tissue through suturing wherein the suture comprises a superelastic or shape memory material; and
closing the incision.
22 . The method of claim 21 , wherein said heart related ailment comprises congestive heart failure.
23 . The method of claim 21 , wherein said heart related ailment comprises ischemic congestive heart failure.
24 . The method of claim 21 , wherein said heart related ailment comprises heart failure associated with regional wall-motion abnormality.
