Abstract

A surgically implantable multiple orifice heart valve having a valve frame with at least two orifices, each of which can accommodate a tissue valve. The multiple orifice heart valve includes a stent frame having a first side, an opposite second side, and multiple orifices or opening, each of which extends from the first side to the second side of the stent frame and is adjacent to at least one of the other multiple orifices or openings.

Claims

1. A heart valve assembly for implantation in a body lumen, the heart valve assembly comprising:

a percutaneously implantable valve frame comprising an outer periphery having both a first side and an opposite second side, wherein the first side is an upper side of the valve frame and the second side is a lower surface of the valve frame;

further wherein the valve frame has an outer shape that is compatible with a shape of a mitral valve;

at least one opening extending through the valve frame from the first side to the second side, the at least one opening including a first opening;

wherein the first opening is defined by an inner frame surrounded by the valve frame, and further wherein a perimeter shape of the first opening differs from a perimeter shape of the valve frame, and further wherein the first opening is offset with respect to a central axis of the valve frame; and

a tissue valve disposed within the first opening, the tissue valve has a curvilinear surface and a generally flat surface collectively forming a substantially D-shape matching at least a portion of the annulus of the mitral valve.

2. The heart valve assembly of claim 1, wherein the valve frame has a structural strength capable of surgical implantation into a patient.

3. The heart valve assembly of claim 1, wherein the valve frame is a gasket that surrounds the outermost periphery of the tissue valve to provide for sealing against paravalvular leakage and to facilitate pannus in-growth for stabilization of the heart valve assembly.

4. The heart valve assembly of claim 1, wherein one portion of the D-shape is planar and is in contact with an inner planar surface of the first opening.

5. The heart valve assembly of claim 1, wherein the curvilinear surface of the D-shape is in contact with an inner curvilinear surface of the first opening.

6. The heart valve assembly of claim 1, further comprising at least two commissure posts extending from the first side of the valve frame and adjacent to the first opening, wherein the tissue valve is coupled to the at least two commissure posts.

7. The heart valve assembly of claim 1, wherein the at least one opening further includes a second opening apart from the first opening.

8. The heart valve assembly of claim 7, further comprising a second tissue valve disposed within the second opening.

9. The heart valve assembly of claim 7, wherein the first opening and the second opening are offset with respect to each other.

10. A heart valve assembly for implantation in a body lumen, the heart valve assembly comprising:

a percutaneously implantable valve frame comprising an outer periphery having both a first side and an opposite second side, wherein the first side is an upper side of the valve frame and the second side is a lower surface of the valve frame;

further wherein the valve frame has an outer shape that is compatible with a shape of a mitral valve;

a first opening and a second opening;

each of the first and second openings extending through the valve frame from the first side to the second side;

wherein the first opening is defined by an inner frame surrounded by the valve frame, and further wherein a perimeter shape of the first opening differs from a perimeter shape of the valve frame, and further wherein the first opening and the second opening are offset with respect to a central axis of the valve frame; and

a first tissue valve disposed within the first opening.

11. The heart valve assembly of claim 10, wherein the first opening and the second opening are offset with respect to each other.

12. The heart valve assembly of claim 10, wherein the first tissue valve has a curvilinear surface and a generally flat surface collectively forming a substantially D-shape matching at least a portion of the annulus of the mitral valve.

13. The heart valve assembly of claim 10, further comprising a second tissue valve disposed in the second opening.
