Abstract:
A stent comprising:a stent body expandable between an un-deployed orientation and a deployed orientation;the stent body having cell defining portions with opposing surfaces defining an open cell bounded by the cell defining portions, the cell having a major axis and a minor axis;the cell defining portions including first and second longitudinal segments each of which includes:a. a longitudinal axis extending parallel to the cell major axis, the longitudinal axes being positioned on opposite sides of the cell major axis; andb. an undulating pattern that defines a plurality of peaks and valleys spaced outwardly and inwardly, respectively, from the longitudinal axes;the first and second longitudinal segments being interconnected at opposite ends thereof;the stent body further including first and second longitudinal connection locations at interconnection points of the interconnected first and second longitudinal segments for connection of the cell to first and second longitudinally adjacent cells, respectively, and first and second transverse connection locations on the first and second longitudinal segments, respectively, for connection of the cell to first and second transversely adjacent cells, respectively;the cell defining portions being symmetrical about both the major axis and the minor axis;the first and second longitudinal connection locations being positioned on the major axis, and the first and second transverse connection locations being positioned on the minor axis;the longitudinal and transverse connection locations each having a transverse width W.sub.c that is at most equal to as a common width W of each of the longitudinal segments; andthe longitudinal and transverse connection locations each having a longitudinal length L.sub.c that is greater than two times as long as the common width W of each of the longitudinal segments.
