Abstract
A polymeric stent has an inner surface with an inner diameter that tapers continuously in size. A method for manufacturing a stent includes blow molding a polymeric tube within a mold having a tapered, cylindrical cavity such that the polymeric tube attains a corresponding tapered shape. The tapered tube is used as a substrate from which a laser cuts interconnecting stent struts.
