Abstract

A method of implanting a prosthetic valve within the heart comprises translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart. A first chamber of the inflatable structure is inflated and then, independently, a second chamber of the inflatable structure is inflated.

Claims

1. A method of implanting a prosthetic valve within the heart, the method comprising:

advancing with a deployment catheter a prosthetic valve comprising an inflatable structure to a first position proximate a native valve of the heart;

inflating a first chamber of the inflatable structure in the first position proximate the native valve of the heart through a first inflation tube that extends at least partially through the deployment catheter and is axially moveable with respect to the deployment catheter;

moving the prosthetic valve to a second position proximate the native valve of the heart

independently inflating a second chamber of the inflatable structure in the second position proximate the native valve of the heart through a second inflation tube that extends at least partially through the deployment catheter and is also axially moveable with respect to the deployment catheter; and

tilting the prosthetic valve off axis by controlling a relative position of at least three members coupled to the prosthetic valve at three separate locations rotationally spaced about the longitudinal axis of the prosthetic valve and extending through the deployment catheter.

2. The method of claim 1, wherein inflating a first chamber of the inflatable structure comprising inflating a distal end of the valve.

3. The method of claim 2, further comprising proximally retracting the valve after the first chamber is at least partially inflated.

4. The method of claim 1, wherein inflating a second chamber of the inflatable structure comprising inflating a proximal end of the valve.

5. A method of implanting a prosthetic valve as in claim 1, additionally comprising decoupling the first and second inflation tubes from the prosthetic valve.

6. A method of implanting a prosthetic valve as in claim 1, additionally comprising the step of removing the native valve.

7. A method of implanting a prosthetic valve as in claim 1, additionally comprising the step of debulking the native valve.

8. A method of implanting a prosthetic valve as in claim 1, additionally comprising the step of performing a balloon valvuloplasty on the native valve.

9. A method of implanting a prosthetic valve as in claim 1, wherein the advancing step comprises advancing the catheter over the aortic arch.

10. A method of implanting a prosthetic valve as in claim 1, wherein the advancing step comprises using a trans apical approach.

11. A method of implanting a prosthetic valve as in claim 1, wherein the inflating a first chamber step comprises inflating the first chamber with a hardenable media.

12. A method of implanting a prosthetic valve as in claim 1, additionally comprising the step of releasing the prosthetic valve from the control members following the independently inflating the second chamber step.

13. A method of implanting a prosthetic valve as in claim 1, additionally comprising the step of permitting perfusion through the valve during the inflating a first chamber step.

14. A method of implanting a prosthetic valve as in claim 13, additionally comprising the step of permitting perfusion through the valve during the tilting step.

15. A method of implanting a prosthetic valve as in claim 1, additionally comprising the step of placing a temporary valve downstream from the native valve.

16. A method of implanting a prosthetic valve as in claim 1, additionally comprising the step of placing an embolic filter downstream from the native valve.

17. A method of implanting a prosthetic valve as in claim 1, wherein the prosthetic valve is functional prior to full inflation of the inflatable cuff

18. A method of implanting a prosthetic valve as in claim 17, wherein the prosthetic valve is functional prior to the releasing step.

19. A method of implanting a prosthetic valve within the heart, the method comprising:

advancing with a deployment catheter a prosthetic valve comprising an inflatable structure to a first position proximate a native valve of the heart;

inflating a first chamber of the inflatable structure in the first position proximate the native valve of the heart through a first inflation tube that extends at least partially through the deployment catheter;

moving the prosthetic valve to a second position proximate the native valve of the heart;

independently inflating a second chamber of the inflatable structure in the second position proximate the native valve of the heart through a second inflation tube that extends at least partially through the deployment catheter; and

tilting the prosthetic valve off axis by controlling a relative position of at least three members coupled to the prosthetic valve at three separate locations rotationally spaced about the longitudinal axis of the prosthetic valve and extending through the deployment catheter
