1. A stent comprising:
- a stent body having a stent axis;
the stent body including a structural member extending in an undulating pattern about a circumference of the stent body;
the structural member including a plurality of segments that extend generally longitudinally along the stent axis; and
at least some of the plurality of segments including pairs of tapered segments having widths that taper as the at least some segments extend longitudinally along the stent axis, the pairs of tapered segments being interconnected by non-tapered segments.

Abstract
The present disclosure relates to a stent including a stent body having a stent axis. The stent body includes structural members defining openings through the stent body. The structural members are provided with regions having different widths. The relative sizes of the widths are selected to control the length of the stent body as the stent body is radially expanded from an un-deployed orientation to a deployed orientation. In one embodiment, the regions having different widths are provided by tapering the widths of selected segments of the structural member.

3. A stent comprising:
-
a stent body having a stent axis;
the stent body including a structural member extending in an undulating pattern about a circumference of the stent body;
a plurality of structural members having peaks and valleys, the structural members also including segments that interconnect the peaks and valleys, wherein the structural members form cell structures interconnected at connection location; and
at least some of the segments of the structural members having widths that taper along lengths of the at least some segments, wherein the widths are larger adjacent the connection locations than adjacent the peaks and valleys.

4. A stent comprising:
-
a stent body having a stent axis;
the stent body including a structural member extending in an undulating pattern about a circumference of the stent body;
the structural member including a plurality of segments that extend generally longitudinally along the stent axis, each of the segments including a first end and a second end; and
at least some of the segments being tapered so as to define a first width adjacent the first end, a second width adjacent the second end and a third width at a midpoint between the first and second ends, the first width being less than the second width, and the third width being greater than the first width and less than the second width.

18. A stent comprising:
-
a stent body having a stent axis;
the stent body including a structural member extending in an undulating pattern about a circumference of the stent body;
the structural member including peaks and valleys, and also including segments that interconnect the peaks and valleys; and
at least some of the segments having a first width adjacent the peak and a second width adjacent the valley, the at least some of the segments being configured to taper along lengths of the at least some segments such that the first width is different than the second width. - View Dependent Claims (19, 20, 21, 22)

23. A stent comprising:
-
a stent body that is radially expandable from an un-deployed orientation to a deployed orientation;
the stent body including structural members defining openings through the stent body;
the structural members including segments having first regions with enlarged widths and second regions with more narrow widths, the first region being located adjacent a first end of the segments and the second region being located adjacent a second end of the segments; and
the relative sizes of the enlarged widths and the more narrow widths are selected to control a length of the stent body as the stent body is expanded from the un-deployed orientation to the deployed orientation.- View Dependent Claims (24, 25, 26, 27)
