Device and method for mitral valve regurgitation treatment
A mitral valve replacement device is adapted to be deployed at a mitral valve position in a human heart. The device has an atrial flange defining an atrial end of the device, a valve body defining a ventricular end of the device, and an annulus support that connects the atrial flange and the valve body, the annulus support including a ring of tabs extending radially therefrom and adapted to engage the native mitral annulus and/or the native leaflet(s) of the human heart. The atrial flange can be seated in the atrium above the native mitral valve annulus in a human heart, and the ring of tabs can engage the native mitral annulus in a manner where the atrial flange and tabs provide a clipping effect to secure the mitral valve replacement device at the native mitral valve position.
1. A mitral valve replacement device adapted to be deployed at a mitral valve position in a human heart, comprising:
an atrial flange defining an atrial end of the device;
a valve body defining a ventricular end of the device;
an annulus support that connects the atrial flange and the valve body, the annulus support including a ring of tabs extending radially therefrom, and a ring of U-shaped sections extending radially outwardly and alternating with the tabs;
wherein the atrial flange has a diameter greater than the diameter of the valve body, and the annulus support has a diameter between that of the diameter of the atrial flange and the diameter of the valve body.
2. The device of claim 1 , further including a leaflet structure positioned at the valve body.
3. The device of claim 1 , further including at least one tail extending from the ventricular end of the valve body.
4. The device of claim 1 , further including a neck positioned between the atrial flange and the ring of U-shaped sections.
5. A mitral valve replacement device adapted to be deployed at a mitral valve position in a human heart, comprising;
an atrial flange defining an atrial end of the device;
a valve body defining a ventricular end of the device;
an annulus support that connects the atrial flange and the valve body, the annulus support including a ring of tabs extending radially therefrom;
wherein the atrial flange has a diameter greater than the diameter of the valve body, and the annulus support has a diameter between that of the diameter of the atrial flange and the diameter of the valve body; and
at least one clip extending from the annulus support.
6. The device of claim 1 , wherein at least a portion of one or more of the atrial flange, the annulus support and valve body is covered with tissue.
7. The device of claim 1 , wherein at least a portion of one or more of the atrial flange, the annulus support and valve body is covered with fabric.
8. The device of claim 1 , wherein at least a portion of one or more of the atrial flange, the annulus support and valve body is covered with tissue and fabric.
9. The device of claim 8 , wherein the tissue and fabric are comprised of a layer of combined tissue and fabric.
10. The device of claim 1 , wherein at least a portion of one or more of the atrial flange, the annulus support and valve body is coated with a biocompatible adhesive.
11. The device of claim 5 , further including a leaflet structure positioned at the valve body.
12. The device of claim 5 , further including at least one tail extending from the ventricular end of the valve body.
13. The device of claim 5 , wherein the annulus support includes a ring of U-shaped sections extending radially outwardly and alternating with the tabs.
14. The device of claim 13 , further including a neck positioned between the atrial flange and the ring of U-shaped sections.
15. The device of claim 5 , wherein at least a portion of one or more of the atrial flange, the annulus support and valve body is covered with tissue.
16. The device of claim 5 , wherein at least a portion of one or more of the atrial flange, the annulus support and valve body is covered with fabric.
17. The device of claim 5 , wherein at least a portion of one or more of the atrial flange, the annulus support and valve body is covered with tissue and fabric.
18. The device of claim 17 , wherein the tissue and fabric are comprised of a layer of combined tissue and fabric.
19. The device of claim 5 , wherein at least a portion of one or more of the atrial flange, the annulus support and valve body is coated with a biocompatible adhesive.
