Abstract

There is disclosed a method of implanting a mitral valve therapy device in a patient'"'"'s coronary sinus adjacent the patient'"'"'s mitral valve annulus. The method includes the steps of positioning the mitral valve therapy device within the coronary sinus of the patient adjacent to the mitral valve annulus, evaluating effectiveness of the device, and assessing arterial perfusion of the heart.

Claims

1. A method of implanting a mitral valve therapy device in a patient'"'"'s coronary sinus adjacent the patient'"'"'s mitral valve annulus, the method comprising the steps of:

positioning the mitral valve therapy device within the coronary sinus of the patient adjacent to the mitral valve annulus of the patient;

evaluating effectiveness of the device; and

assessing arterial perfusion of the heart.

2. The method of claim 1 including the further step of adjusting the position of the device after the assessing step.

3. The method of claim 1 including the further step of removing the device after the assessing step.

4. The method of claim 1 wherein the device includes a distal anchor and a proximal anchor, wherein the positioning step includes deploying the distal anchor within the coronary sinus and wherein the evaluating step includes pulling proximally on the device.

5. The method of claim 4 wherein the assessing step is performed as the device is pulled proximally.

6. The method of claim 5 including the further step of deploying the proximal anchor while pulling proximally on the device.

7. The method of claim 6 including the further step of confirming effectiveness of the device after deploying the proximal anchor.

8. The method of claim 6 including the further step of assessing arterial perfusion of the heart after deploying the proximal anchor.

9. The method of claim 8 including the further step of recapturing the proximal anchor after the deploying and assessing steps.

10. The method of claim 8 including the further step of removing the device after the deploying and assessing steps.

11. The method of claim 1 wherein the assessing step includes performing coronary angiography.

12. The method of claim 1 wherein the assessing step includes intravascular ultrasound.

13. The method of claim 1 wherein the assessing step includes fractional flow reserve analysis.

14. The method of claim 1 wherein the assessing step includes performing an echocardiography.

15. The method of claim 1 wherein the assessing step includes the step of detecting for myocardial ischemia.

16. The method of claim 1 wherein the assessing step includes the step of detecting a chemical marker of ischemia.

17. The method of claim 15 wherein the detecting step includes taking an electrocardiogram.

18. The method of claim 1 including the further step of determining anatomical features of the coronary sinus adjacent to the mitral valve annulus.

19. The method of claim 18 wherein the determined anatomical features include one of shape, diameter, and length.

20. The method of claim 18 including the further steps of providing a plurality of mitral valve therapy devices, each device corresponding to a respective different set of the anatomical features and selecting one of the plurality of mitral valve therapy devices after determining the anatomical features of the coronary sinus.

21. A method of implanting a mitral valve therapy device in a patient'"'"'s coronary sinus adjacent the patient'"'"'s mitral valve annulus, the device including a distal anchor and a proximal anchor, the method comprising the steps of:

positioning the mitral valve therapy device within the coronary sinus adjacent to the mitral valve annulus;

deploying the distal anchor;

evaluating effectiveness of the device;

performing an arterial perfusion assessment of the heart;

deploying the proximal anchor; and

performing a second arterial perfusion assessment of the heart.

22. The method of claim 21 wherein the evaluating step includes pulling proximally on the device.

23. The method of claim 22 wherein the assessing step is performed as the device is pulled proximally.

24. The method of claim 23 wherein the proximal anchor is deployed while the device is pulled proximally.

25. The method of claim 21 including the further step of confirming effectiveness of the device after deploying the proximal anchor.

26. The method of claim 21 wherein at least one of the performing steps includes one of coronary angiography, intravascular ultrasound, fractional flow reserve analysis, echocardiography, and myocardial ischemia detection.

27. The method of claim 26 wherein the myocardial ischemia detection includes taking an electrocardiogram.

28. The method of claim 21 including the further step of determining anatomical features of the coronary sinus adjacent to the mitral valve annulus.

29. The method of claim 28 wherein the determined anatomical features include one of shape, diameter, and length.

30. The method of claim 28 including the further steps of providing a plurality of mitral valve therapy devices, each device corresponding to a respective different set of the anatomical features and selecting one of the plurality of mitral valve therapy devices after determining the anatomical features of the coronary sinus.

31. The method of claim 21 including the further step of recapturing the distal anchor after the step of performing an arterial perfusion assessment of the heart.

32. The method of claim 21 including the further step of recapturing the proximal anchor after the step of performing a second arterial perfusion assessment of the heart.

33. A method of optimizing patient outcome while performing a procedure in the venous system of a patient'"'"'s heart, the method comprising the steps of:

performing a procedure in the venous system of the patient'"'"'s heart;

evaluating effectiveness of the procedure; and

assessing arterial perfusion of the heart.

34. The method of claim 33 including the further step of performing a further procedure in the venous system of the patient'"'"'s heart after the evaluating step.

35. The method of claim 33 wherein the performing step comprises positioning a mitral valve therapy device within the coronary sinus adjacent to the mitral valve annulus of the patient'"'"'s heart.

36. The method of claim 35 including the further step of repositioning the device after the evaluating step.

37. The method of claim 35 including the further step of removing the device after the evaluating step.
