Claim:
1. A stent in an expanded-state and neutral configuration comprising: a plurality of undulating circumferential portions, each circumferential portion comprising alternating peaks and valleys; and a plurality of longitudinally extending portions connecting the plurality of undulating circumferential portions; wherein: (i) each of the plurality of longitudinally extending portions comprising a first longitudinally extending strut and a second longitudinally extending strut circumferentially offset with respect to the first longitudinally extending strut, the first longitudinally extending strut and the second longitudinally extending strut being interconnected by a connecting portion, the connecting portion comprising a first strut segment connected to the first longitudinally extending strut and a second strut segment connected to the second longitudinally extending strut, the first strut segment and the second strut segment are interconnected to define a single connecting apex therebetween; (ii) a pair of circumferentially adjacent first longitudinally extending struts in a pair of circumferentially adjacent longitudinally extending portions are circumferentially spaced at a first distance and circumferentially adjacent second longitudinally extending struts in the pair of circumferentially adjacent longitudinally extending portions are circumferentially spaced at a second distance, the first distance being greater than the second distance; and (iii) circumferentially spaced connection portions being configured such that the single connecting apex in each circumferentially spaced connection portion is interposed in alternating longitudinally aligned pairs of a peak and a valley in adjacent undulating circumferential portions.
