Abstract

A shaping device and a cardiac lead, both adapted to be disposed in a coronary sinus of a patient'"'"'s heart, are provided. In one method, a patient is treated by deploying in the patient'"'"'s coronary sinus a shaping device and a cardiac lead and using the shaping device to modify mitral valve geometry.

Claims

1. A method for treating a patient'"'"'s heart comprising:

deploying in the patient'"'"'s coronary sinus a shaping device and a cardiac lead; and

using the shaping device to modify mitral valve geometry.

2. The method of claim 1 wherein the deploying step comprises deploying shaping device in the coronary sinus before deploying the cardiac lead in the coronary sinus.

3. The method of claim 2 wherein the deploying step comprises passing the cardiac lead through a portion of the shaping device.

4. The method of claim 1 wherein the deploying step comprises deploying the cardiac lead in the coronary sinus before deploying the shaping device in the coronary sinus.

5. The method of claim 4 wherein the deploying step comprises disposing the cardiac lead between a portion of shaping device and a coronary sinus wall.

6. The method of claim 1 wherein the deploying step comprises expanding an anchor of the shaping device.

7. The method of claim 6 wherein the using step comprises applying a proximally-directed force on the shaping device after expanding the anchor.

8. The method of claim 1 wherein the deploying step comprises deploying the shaping device and cardiac lead such that a portion of the shaping device surrounds a portion of the cardiac lead.

9. The method of claim 1 wherein the deploying step comprises deploying the shaping device and cardiac lead such that the shaping device is adjacent to the cardiac lead.

10. The method of claim 9 wherein the deploying step comprises deploying the shaping device and cardiac lead such that the shaping device contacts the cardiac lead.

11. The method of claim 1 wherein the cardiac lead is a cardiac resynchronization therapy lead.

12. The method of claim 1 or 11 wherein the cardiac lead is an IPG, ICD, PCD or pacemaker lead.

13. The method of claim 1 wherein the shaping device comprises a retention member adapted to hold the cardiac lead within the coronary sinus.

14. A method for treating a patient'"'"'s heart comprising:

deploying in the patient'"'"'s coronary sinus a shaping device comprising one more electrodes and which is adapted to couple to a conventional electrophysiology (EP) system; and

using the shaping device to modify mitral valve geometry.

15. The method of claim 14, wherein the EP system is used to defibrillate a right and left ventricle.

16. The method of claim 15;

wherein the one or more electrodes are located on a portion of the shaping device configured to contact an inner wall of the coronary sinus which is proximate a left atrium of the patient'"'"'s heart.

17. A device for treating a condition of the heart and which is configured to be deployed in a coronary sinus, said device comprising:

expandable first and second anchors interconnected by a connecting member disposed between the first and second anchors; and

a retention member adapted for holding a cardiac lead in a coronary sinus.

18. The device of claim 18, wherein the retention member is a loop, hook, grasper or the like.

19. The device of claim 18 wherein the cardiac lead is an IPG, ICD, PCD or pacemaker lead.

20. A device for treating a condition of a patient'"'"'s heart and which is configured to be deployed in a coronary sinus, said device comprising:

a distal anchor;

a proximal anchor;

a connecting member disposed between the distal and proximal anchors;

one or more electrodes; and

a lead wire which operationally couples the one or more electrodes to an EP system.

21. The device of claim 20 wherein the distal and proximal anchors further comprise a distal and proximal crimp tube respectively.

22. The device of claim 20 wherein the one or more electrodes are located on the distal anchor, the proximal anchor or both.

23. The device of claim 21 wherein the one or more electrodes are located on a connecting member, a crimp tube or both.

24. The device of claim 20 wherein one or more of the crimp tubes, connector or both are adapted to couple to the EP system.

25. The device of claim 20 wherein the EP system is an IPG, ICD, PCD or pacemaker system.

26. A device that effects mitral valve annulus geometry of a heart, comprising:

a first anchor configured to be positioned within and anchored to the coronary sinus of the heart adjacent the mitral valve annulus;

a second anchor configured to be positioned proximal to the first anchor and adjacent the mitral valve annulus; and

a connecting member attached between the first and second anchors, the first anchor being configured to occupy less than all of the coronary sinus to permit a cardiac lead to be passed by the first anchor.

27. The device of claim 26 wherein the first anchor includes a loop through which the cardiac lead may be passed.

28. The device of claim 26 wherein the second anchor is positionable within the coronary sinus and wherein the second anchor is configured to occupy less than all of the coronary sinus to permit the cardiac lead to be passed by the second anohor.

29. The device of claim 28 wherein the second anchor includes a loop through which the cardiac lead may be passed.

30. The device of claim 29 wherein each of the first and second anchors includes a loop through which the cardiac lead may be passed.
