Abstract

A prosthetic mitral valve includes an anchor assembly, an annular strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The annular strut frame is disposed radially within the anchor assembly. An atrial end of the annular strut frame is attached to the anchor assembly such that a ventricular end of the annular strut frame is spaced away from the anchor assembly.

First claim

The invention claimed is:

1. A system comprising:
a prosthetic mitral valve configured to expand from a collapsed configuration to an expanded configuration and including:
an anchor assembly comprising an atrial anchor, a ventricular anchor, and a central portion therebetween, in the expanded configuration, the atrial anchor extends radially outwards relative to the central portion and includes a plurality of extensions,
an annular strut frame disposed radially within the anchor assembly and attached thereto, and
a plurality of replacement leaflets secured to the annular strut frame, wherein at least one of the plurality of extensions includes an eyelet having a hook therein for attaching tether thereto for delivery of the prosthetic mitral valve; and
a tether for attaching to the hook of the prosthetic mitral valve for delivery of the prosthetic mitral valve.

2. The system of claim 1 , wherein the annular strut frame is attached to the anchor assembly in the collapsed configuration.

3. The system of claim 1 , wherein the prosthetic mitral valve is configured to self-expand from the collapsed configuration to the expanded configuration.

4. The system of claim 1 , wherein the strut frame includes a plurality of linear posts and a plurality of circumferential zig-zag features extending therearound.

5. The system of claim 1 , wherein in the expanded configuration, the ventricular anchor extends outward from the central portion.

6. The system of claim 5 , wherein the anchor assembly forms an hour-glass shape.

7. The system of claim 1 , wherein the hooks are positioned on every other extension around the circumferential direction of the anchor assembly.

8. The system of claim 1 , wherein the anchor assembly includes a plurality of hooks extending from the central portion, the hooks configured to engage tissue.

9. The system of claim 1 , wherein each hook is in the form of a double eyelet hook.

10. The system of claim 1 , wherein the atrial and ventricular anchors are configured to compress native cardiac tissue proximate to a mitral valve orifice therebetween.
