Claim 8:
9. A valve prosthesis comprising:
a valve;
a stent structure comprising:
a proximal most row of elongate closed cells each having a length, proximal apices, distal apices, and a plurality of angled strut segments;
a second row of elongate closed cells at least partially distally of the proximal most row, each elongate closed cell of the second row having a length, proximal apices, distal apices, and a plurality of angled strut segments;
a distal most row of elongate closed cells at least partially distally of the second row of elongate closed cells, each elongate closed cell of the distal most row having a length, proximal apices, distal apices and a plurality of angled strut segments;
wherein the overall length of each of the elongate closed cells of the distal most row of elongate closed cells is greater than the length of every cell proximal of the distal most row of elongate closed cells;
wherein the overall length of a plurality of elongate closed cells of the second row of elongate closed cells is greater than every elongate closed cell proximal of the plurality of elongate closed cells of the second row of elongate closed cells;
wherein a plurality of proximal angled strut segments of the proximal most row of elongate stent cells are longer than a plurality of distal angled strut segments of the proximal most row of elongate closed cells;
wherein the valve tapers inwardly from a proximal valve region to a distal valve region; and
wherein a proximal end of the stent flares relative to a longitudinal axis of the valve prosthesis.
