Patent abstract
A method and apparatus for simultaneously polishing the inner and outer surfaces of an unpolished polymeric stent using a heat process. The unpolished stent can be mounted, for example, on a “spiral-mandrel,” a tubular helical structure with gaps in between a series of coils of the structure. Heat from a heat source can then applied to the spiral-mandrel at a range between the glass transition temperature and melting temperature of the polymer of the stent.
