A prosthetic valve comprising:
- a wire frame comprising a generally tubular body portion, an interior area, a longitudinal axis, a first end comprising a plurality of crowns, and a second end comprising a greater number of crowns than the first end, wherein the wire frame comprises a plurality of adjacent rows of modified diamond-shaped structures extending between the first and second ends;
- and
- a valve structure attached within the interior area of the wire frame, the valve structure comprising a plurality of leaflets.
The prosthetic valve comprising:
- a wire frame comprising a generally tubular body portion, an interior area, a longitudinal axis, a first end comprising a plurality of crowns, and a second end comprising a greater number of crowns than the first end, wherein the wire frame comprises a plurality of adjacent rows of modified diamond-shaped structures extending between the first and second ends, wherein each of the crowns comprises two struts extending from a common intersection point, and wherein at least one of the struts tapers in cross-sectional area from the intersection point toward a central area of the wire frame;
