Abstract
A pattern is used to form a stent scaffold from a polymeric precursor tube having a particular outer diameter. A new pattern can be derived from a base pattern, wherein the new pattern can be used to form a stent scaffold from a precursor tube having an outer diameter ODsmaller than that needed for the base pattern. The new pattern can be derived by determining the shape of a stent scaffold, having the base pattern, after having been radially compressed to OD. The radially compressed shape is used to design the new pattern, which is applied to a precursor tube having an outer diameter OD. The new pattern can have a plurality of W-shaped closed cells, each W-shape closed cell bounded by struts oriented in such a way to form interior angles from about 80 degrees to about 95 degrees between every two adjacent struts.
