Abstract
Elastic compressible stents have a plurality of proximal and distal apices joined by struts that are essentially straight. The stent can have a polygonal cross-sectional shape, such as a dodecahedron shape. Elastic compressible stents can be made by a method that includes winding stent wire around an outer surface of a longitudinal axis of a polygonal cross-sectional shaped mandrel into a desired shape that is polygonal in an elevation orthogonal to the longitudinal axis. The stent can be formed by setting the wound stent wire in the desired polygonal final shape. The polygonal cross-sectional shape mandrel can be a mandrel having a multi-sided outer surface. Stents can include graft material attached to the stent.
