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.
Claims7
1-20. (canceled)
21:
- A heart valve assembly for implantation in a body lumen, the stent assembly comprising:
- a percutaneously implantable valve frame comprising a first side, an opposite second side, 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;
- and
- a tissue valve disposed within the at least one opening, the tissue valve has a curvilinear surface forming a substantially D-shape matching the annulus of the mitral valve.
2 more elements
22:
- The heart valve assembly of claim 21, wherein the stent frame has a structural strength capable of surgical implantation into a patient.
23:
- The heart valve assembly of claim 21, 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.
24:
- The heart valve assembly of claim 21, wherein one portion of the D-shape is planar and is in contact with an inner planar surface of the at least one opening.
25:
- The heart valve assembly of claim 21, wherein the curvilinear surface of the D-shape is in contact with an inner curvilinear surface of the at least one opening.
26:
- The heart valve assembly of claim 21, further comprising at least two commissure posts extending from the first side of the valve frame and adjacent to the at least one opening, wherein the tissue valve is coupled to the at least two commissure posts.
