Abstract:
1. A stent of comprising: a stent body defining a longitudinal axis, the stent body including a plurality of structural members extending in an undulating pattern about a circumference of the stent body; longitudinally adjacent structural members being connected to define a plurality of cells, each cell having a plurality of outer peaks and inner valleys coupled by segments that extend generally longitudinally between the outer peaks and inner valleys, at least some of the inner valleys of each cell being free from connection with adjacent inner valleys; each cell being connected to a circumferentially adjacent cell about a circumference of the stent body at a circumferential connection region, each circumferential connection region connecting adjacent inner valleys; at least one cell including a pair of first segments extending in opposed longitudinal directions from the circumferential connection region to respective first and second outer peaks, the first segments each having a width that tapers along the longitudinal axis from a first width adjacent the circumferential connection region to a second width adjacent the respective first and second outer peaks of the at least one cell, the first width being greater than the second width; wherein the at least one cell is connected to a longitudinally adjacent cell at a longitudinal connection region, the longitudinal connection region connecting adjacent outer peaks of the at least one cell and the longitudinally adjacent cell; and the at least one cell including a second segment having a width that tapers along the longitudinal axis from a third width adjacent the longitudinal connection region to a fourth width adjacent an inner valley of the at least one cell, the third width being greater than the fourth width.
