Abstract:
A method of manufacturing a stent includes forming a wave form having a plurality of struts and a plurality of crowns. Each crown connects two adjacent struts. The wave form has a center and two portions extending from opposite sides of the center. The method includes wrapping a first portion of the wave form about a longitudinal axis in a first direction at a first pitch angle, starting at the center of the wave form, to define at least one turn oriented at the first pitch angle, and wrapping a second portion of the wave form about the longitudinal axis in a second direction that is opposite the first direction at a second pitch angle, starting at the center of the wave form, to define at least one turn oriented at the second pitch angle. The first pitch angle is opposite the second pitch angle.
