Stent with dual support structure
First Claim
1. An intraluminal stent comprising:
- a stent body expandable from an un-deployed orientation to a deployed orientation;
the stent body having cell defining portions with opposing surfaces defining an open cell bounded by the cell defining portion, the cell having a major axis (XM) and a minor axis (Xm);
each cell defining portion including a first longitudinal segment and a second longitudinal segment, the first and second longitudinal segments connected at first and second ends, each of the first and second longitudinal segments comprising;
(a) first and second spaced-apart longitudinal elements having a spacing therebetween;
(b) a longitudinal axis (Xa), the longitudinal axis (Xa) for the first longitudinal segment positioned parallel to and on a first side of the cell major axis (XM), and the longitudinal axis (Xa) for the second longitudinal segment positioned parallel to and on a second opposite side of the cell major axis (XM);
(c) an undulating pattern comprising a plurality of peaks spaced outwardly from and a plurality of valleys spaced inwardly from the longitudinal axes (Xa), the spacing extending at least partially along the undulating pattern between the first and second ends;
the first and second longitudinal segments being configured such that the spacing between the first and second spaced-apart longitudinal elements remains substantially unchanged as the stent body is expanded from the un-deployed orientation to the deployed orientation.

Abstract
A intraluminal stent comprises a reticulated tube having an un-deployed diameter and expandable to an enlarge diameter. The tube includes a structural beam extending between first and second ends. The structural beam changes from a first geometry to a second geometry when the tube changes from the un-deployed diameter to the enlarged diameter. The structural beam includes first and second longitudinal elements each extending at least partially between the first and second ends and with a spacing between the first and second elements. Each of said first and second elements changes from the first geometry to the second geometry when the tube changes from the un-deployed diameter to the enlarged diameter for the spacing to remain substantially unchanged as the tube changes from the un-deployed diameter to the enlarged diameter.
