1. A prosthesis comprising:
- a collapsible and reexpandable frame, the frame having a longitudinal axis, the frame comprising;
first, second, and third sets of struts;
wherein the first and second sets of struts are connected at a first plurality of nodes to define a first row of expandable cells;
wherein the second and third sets of struts are connected at a second plurality of nodes to define a second row of expandable cells, the first row of expandable cells being proximal to the second row of expandable cells;
wherein each strut of the first set of struts comprises a first proximal segment with a first width, a first intermediate segment with a second width, and a first distal segment with a third width;
wherein each strut of the second set of struts comprises a second proximal segment with a fourth width, a second intermediate segment with a fifth width, and a second distal segment with a sixth width;
wherein each strut of the third set of struts comprises a third proximal segment with a seventh width, a third intermediate segment with an eighth width, and a third distal segment with a ninth width;
wherein the second width is smaller than each of the first and third widths;
wherein the fifth width is smaller than each of the fourth and sixth widths; and
wherein the eighth width is smaller than each of the seventh and ninth widths.

Abstract
A prosthesis can include a collapsible, reexpandable frame comprising first, second, and third sets of struts that define first and second rows of expandable cells. In some embodiments, the struts of the first, second, and third set of struts can be tapered. In some embodiments, the frame can include an intermediate section and an inflow section that is proximal to the intermediate section. The inflow section can include a concave saddle portion that is adjacent the intermediate section, and an outwardly flared portion.
