Abstract

An instrument for deploying a cardiac valve prosthesis, including a plurality of radially expandable portions, at an implantation site, includes a plurality of deployment elements each independently operable to obtain the radial expansion of a radially expandable portion of the valve prosthesis. A method for deploying the cardiac valve prosthesis includes advancing the instrument to an implant site and independently actuating the radially expandable portions.

Claims

1. A device for transfemoral delivery of an expandable heart valve prosthesis, the device comprising a low friction material.

2. The device of claim 1 in which the low friction material comprises ultra-high molecular weight material.

3. The device of claim 1 in which the low friction material comprises PTFE.

4. The device of claim 1 in which the low friction material comprises Teflon™

.

5. The device of claim 1 in which the low friction material is coated on the device.

6. The device of claim 1 in which the device is made from the low friction material.

7. The device of claim 1 further comprising a cap, in which the cap is made from low friction material.

8. The device of claim 1 further comprising a cap, in which the cap is coated with a low friction material.

9. The device of claim 1 further comprising an interior portion, the interior portion comprising the low friction material.

10. The device of claim 9 wherein the interior portion forms part of an interior portion of a chamber.

11. The device of claim 10 further comprising an expandable heart valve prosthesis.

12. A device for transfemoral delivery of an expandable heart valve prosthesis, the device comprising a lubricious material.

13. The device of claim 12 wherein the lubricious material is coated onto the device.

14. The device of claim 12 further comprising a cap made from the lubricious material.

15. The device of claim 12 further comprising a cap coated with the lubricious material.
