Abstract
A stent includes a continuous wave form wrapped around a longitudinal axis of the stent at a first pitch angle to define a first helix comprising a plurality of turns. The wave form includes a plurality of struts and a plurality of crowns. Each crown connects adjacent struts within a turn to define the continuous wave form. The stent also includes a plurality of connections configured to connect selected crowns of adjacent turns so that when the stent is in an unexpanded condition, the plurality of connections are aligned at a second pitch angle to define a second helix, and when the stent is in an expanded condition, at least some of the connections align along a substantially straight line parallel to the longitudinal axis of the stent.
