Abstract

A replacement heart valve assembly has a stent frame and a replacement valve. The replacement valve has a plurality of leaflets and a valve frame. The leaflets are attached to the valve frame. Further, the assembly has a plurality of suspension struts attached to the stent frame and the valve frame. The valve frame is suspended within the stent frame via the suspension struts. In some embodiments, the assembly further has a sealing member attached to the stent frame to prevent leakage around the replacement heart valve assembly.

Claims (15)

1. A replacement heart valve assembly comprising:

a stent frame;

a replacement valve, the replacement valve having a plurality of leaflets and a valve frame, the valve leaflets attached to the valve frame;

a plurality of suspension struts attached to the stent frame and the valve frame, wherein the valve frame is suspended within the stent frame via the suspension struts; and

a sealing member, the sealing member attached to the stent frame.

2. The replacement heart valve assembly of claim 1 , wherein the replacement valve has three leaflets.

3. The replacement heart valve assembly of claim 1 , wherein the stent frame has a distal end and the suspension struts are located at the distal end.

4. The replacement heart valve assembly of claim 1 , wherein the suspension struts extend radially inwardly from the stent frame.

5. The replacement heart valve assembly of claim 1 having a deployed configuration, wherein, in the deployed configuration, the stent frame is elliptical and the valve frame is circular.

6. The replacement heart valve assembly of claim 1 , wherein at least a portion of the sealing member is disposed exteriorly to the stent frame.

7. A replacement heart valve assembly comprising:

a stent frame;

a replacement valve, the replacement valve having a plurality of leaflets and a valve frame, the valve leaflets attached to the valve frame;

a plurality of suspension struts attached to the stent frame and the valve frame, wherein the valve frame is suspended within the stent frame via the suspension struts and the suspension struts extend radially inwardly from the stent frame and terminate at the valve frame; and

a sealing member, the sealing member attached to the stent frame.
