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 segments having widths that taper as the at least some segments extend longitudinally along the stent axis.

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.

20. A stent comprising:
-
a stent body having a stent axis, the stent body being radially expandable from a non-deployed orientation having a first length to a deployed orientation having a second length;
the stent body including a structural member extending in an undulating pattern about a circumference of the stent body; and
the first length being substantially equal to the second length.

21. A method for making a stent, the method comprising:
-
constructing a stent body having a stent axis, the stent body including structural members defining openings through the stent body; and
during construction of the stent body, providing at least some of the structural members with regions having first and second different widths, the relative sizes of the first and second widths being selected to control a length of the stent body as the stent body is radially expanded from an un-deployed orientation to a deployed orientation. - View Dependent Claims (22, 23, 24, 25, 26)

27. 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; 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 (28, 29, 30, 31)
