1. A prosthesis comprising:
- a collapsible and re-expandable frame, the frame having an inflow edge and a longitudinal axis, the frame comprising;
first, second, and third sets of struts;
wherein struts of the first set of struts are connected to adjacent struts of the first set of struts at a first plurality of nodes at the inflow edge;
wherein the first and second sets of struts are connected at a second plurality of nodes to define a first row of expandable cells;
wherein the second and third sets of struts are connected at a third 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 node of the second plurality of nodes has a first length;
wherein each node of the third plurality of nodes has a second length; and
wherein the first length is longer than the second length.

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.
