摘要： A method of manufacturing a stent (10) includes forming a wave form (20) having a plurality of struts (30) and a plurality of crowns (32). Each crown connects two adjacent struts. The wave form has a central portion (24) and two end portions (26, 28) located on opposite sides the central portion. Some of the struts located in the end portions have lengths longer and/or shorter than an average length of all of the struts of the wave form. The method includes wrapping the wave form about a longitudinal axis (LA) to define a plurality of turns (22) so that an end turn is oriented at an angle relative to the longitudinal axis, a second turn is at a first pitch angle that is less than the angle that the end turn is disposed relative to the longitudinal axis, a third turn is at a second pitch angle that is less than the first pitch angle, and a fourth turn is at a third pitch angle that is less than the second pitch angle.

摘要： A stent (10) includes a continuous wave form wrapped around a longitudinal axis of the stent at a pitch to define a helix comprising a plurality of turns (20). The wave form includes a plurality of struts (22) and a plurality of crowns (24). 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. Unconnected crowns of adjacent turns that substantially face each other are spaced from each other and define a gap therebetween. The gap between the unconnected crowns of adjacent turns is variable around a circumference of the stent.
