Claim 0:
1. A valve prosthesis comprising:
a substantially cylindrical proximal region;
a distal region;
a tapered region disposed between the proximal and distal regions;
a stent structure;
a supra-annular valve disposed substantially within the tapered region, the supra-annular valve having a proximal end, a distal end, a proximal region, and a distal region;
the stent structure comprising:
a proximal most row of elongate closed cells disposed at least partially in the proximal region, each elongate closed cell having a length, a shape, first and second proximal angled struts having a length, and first and second distal angled struts having a length, wherein the length of a plurality of the first and second distal angled struts is shorter than the length of a plurality of the first and second proximal angled struts;
an intermediate row of elongate closed cells disposed at least partially in the tapered region and at least partially distally of the proximal most row of elongate closed cells, each elongate closed cell having a length, a shape, first and second proximal angled struts having a length, and first and second distal angled struts having a length, wherein the length of each of the first and second proximal angled struts is less than the length of a plurality of the first and second distal angled struts, and wherein the intermediate row of cells at least partially abuts the proximal most row of cells;
a distal row of elongate closed cells disposed at least partially in the distal region and at least partially distally of the proximal most and second rows of elongate closed cells, each elongate closed cell having a length and a shape;
wherein the length of each of the elongate closed cells in the intermediate row is less than the length of each of the elongate closed cells in the distal row of elongate closed cells;
wherein the length of each of the elongate closed cells in the proximal most row of elongate closed cells is less than the length of a plurality of the elongate closed cells in the intermediate row of elongate closed cells;
wherein the shape of the elongate closed cells in the proximal most row of elongate closed cells is different than the shape of the elongate closed cells in the intermediate row of elongate closed cells;

wherein the distal region of the valve tapers inwardly toward a longitudinal axis of the valve prosthesis.
