Abstract
A stent includes a wave form having a plurality of struts and a plurality of crowns with each crown connecting two adjacent struts. The wave form is wrapped around a longitudinal axis to define a plurality of turns. The stent includes a first connection that connects an end of the wave form to an adjacent crown in a first turn that defines an end of the stent, and a second connection that connects a first crown of the wave form to an adjacent crown in a second turn.
