Abstract

A prosthetic mitral valve comprising an expandable anchor comprising a first anchor, a central portion and a second anchor; wherein the first anchor comprises a first outer frame and a second outer frame, the first outer frame comprising a plurality of first arcs joined together, and the second outer frame comprising a plurality of second arcs joined together, wherein the plurality of first arcs are out of phase relative to the plurality of second arcs when the first anchor is viewed in an end view from the first anchor to the second anchor; and a plurality of replacement leaflets secured to the expandable anchor.

Claims

1. A prosthetic mitral valve comprising:

an expandable anchor comprising a first anchor, a central portion and a second anchor,

wherein the first anchor comprises a first outer frame and a second outer frame,

wherein, the first outer frame and the second outer frame expands radially outward from the central portion, the first outer frame comprising a plurality of first arcs joined together, and

the second outer frame comprising a plurality of second arcs joined together,

wherein the plurality of first arcs are approximately 90 degrees out of phase relative to the plurality of second arcs when the first anchor is viewed in an end view from the first anchor to the second anchor; and

a plurality of replacement leaflets secured to the expandable anchor.

2. The prosthetic mitral valve of claim 1, wherein the first plurality of arcs are movable relative to the second plurality of arcs.

3. The prosthetic mitral valve of claim 1, wherein the first and second outer frames are substantially circular.

4. The prosthetic mitral valve of claim 1, wherein the proximal anchor and distal anchor are substantially parallel to one another.

5. The prosthetic mitral valve of claim 1, wherein the device is configured to foreshorten upon expansion of the proximal anchor, distal anchor, and central portion from the constrained configuration to the expanded configuration.

6. The prosthetic mitral valve of claim 1, wherein the proximal anchor and the distal anchor each have a diameter in the expanded configuration that is greater than a diameter of the central portion in the expanded configuration.

7. The prosthetic mitral valve of claim 1 wherein the second anchor comprises a plurality of arcs joined together.

8. A prosthetic mitral valve comprising:

an expandable anchor comprising a first anchor, a central portion and a second anchor,

wherein the first anchor comprises a first outer frame and a second outer frame,

wherein, the first outer frame and the second outer frame expands radially outward from the central portion, the first outer frame comprising a plurality of first arcs joined together, and

the second outer frame comprising a plurality of second arcs joined together,

wherein the plurality of first arcs are approximately 90 degrees out of phase relative to the plurality of second arcs when the first anchor is viewed in an end view from the first anchor to the second anchor; and

a plurality of replacement leaflets secured to the expandable anchor;

wherein the device is configured to foreshorten upon expansion of the proximal anchor, distal anchor, and central portion from the constrained configuration to the expanded configuration.

9. The prosthetic mitral valve of claim 8, wherein the first plurality of arcs are movable relative to the second plurality of arcs.

10. The prosthetic mitral valve of claim 8, wherein the first and second outer frames are substantially circular.

11. The prosthetic mitral valve of claim 8, wherein the proximal anchor and distal anchor are substantially parallel to one another.

12. The prosthetic mitral valve of claim 8, wherein the proximal anchor and the distal anchor each have a diameter in the expanded configuration that is greater than a diameter of the central portion in the expanded configuration.

13. The prosthetic mitral valve of claim 8, wherein the second anchor comprises a plurality of arcs joined together.
