Patent ID: 7842077

Claim:
A bifurcated stent comprising: a first stent portion having first and second ends with an intermediate section therebetween, the stent further having a longitudinal axis and a plurality of longitudinally disposed cells, each of the cells having struts formed in the shape of waves, said waves having a spatial frequency along the length of the stent wherein each cell has an opening therein; and a second stent portion having first and second ends with an intermediate section therebetween, the stent further having a longitudinal axis and a plurality of longitudinally disposed cells, wherein each cell has an opening therein; and each of said stent portions capable of expanding from a first respective diameter to a larger second respective diameter; and wherein said second stent portion is configured in its said first respective diameter to pass through a cell of the first stent portion; and wherein the spatial frequency of the wave associated with each of the struts in the first stent portion is decreased in a first end region lying proximate to the first end and in a second end region lying proximate to the second end, in comparison to the spatial frequency of the wave in the intermediate section, by a factor of as great as twenty percent.
