A method for manufacturing a stent, includes the steps of winding stent wire around the outer surface of a longitudinal axis of a mandrel into a desired final shape that is polygonal in an elevation orthogonal to the longitudinal axis, and forming a stent by setting the wound stent wire in the desired polygonal final shape. The outside diameter of the stent formed will be in co-columnar apposition with a blood vessel in which it is implanted. The mandrel employed in the methods can have a multiple-sided outer surface and a longitudinal axis.
