Abstract

A composite biomaterial having a continuous metal sheet with arcuate members that define a first fenestration pattern, and a polymer layer over at least one surface of the continuous metal sheet. The arcuate members elastically stretch to allow the continuous metal sheet to bend in more than one axis without buckling or wrinkling.

Claims

1-16. -16. (canceled)

17. A valve comprising:

a first frame member having a distal end defining a distal cross-sectional area and a proximal end defining a proximal cross-sectional area;

a first valve leaflet secured to the first frame member with rivets, the first valve leaflet including a first inflow surface and a first outflow surface opposite the first inflow surface, and being configured to shift between an open position and a closed position; and

a sinus defined by a volume between the first outflow surface of the first valve leaflet in the open position and the circular proximal cross-sectional area defined by the distal end of the second frame member and the proximal end of the first frame member.

18. The valve of claim 17, further comprising:

a second frame member having a distal end connected to the proximal end of the first frame member, where the distal end of the second frame member and the proximal end of the first frame member define a circular proximal cross sectional area; and

a third frame member connected to a middle portion of the first frame member, where a proximal end of the third frame member defines a circular proximal cross-sectional area approximately equal to the circular proximal cross-sectional area defined by the distal end of the second frame member and the proximal end of the first frame member.

19. The valve of claim 17, the valve leaflet comprising a border strip, wherein the border strip of the valve leaflet is attached to the valve frame.

20. The valve of claim 19, the border strip defining openings, the rivets passing through the border strip openings and through the frame member.

21. The valve of claim 17, the rivets comprising the same material as the valve frame.

22. The valve of claim 17, the proximal cross-sectional area of the first frame member larger than the distal cross-sectional area of the first frame member.

23. The valve of claim 17, the rivets comprising a radiopaque material.

24. The valve of claim 17, the rivets coated with a radiopaque material.
