Claim Text:
1. A degradable and bioresorbable polymeric stent that is substantially resistant to relaxation-related negative recoil when expanded mechanically to a final predetermined diameter in a lumen of a tube, duct, or vessel of a mammalian subject, said polymeric stent being formed by the following steps: (a) heating a polymeric stent, which is at the final predetermined diameter to a temperature sufficiently above the Tg of a polymeric material that forms said polymeric stent, for a time sufficient to erase memory of previous processing of said polymeric stent; and (b) rapidly cooling said polymeric stent at a temperature below the Tg of the polymeric material to quench said polymeric stent and provide a polymeric stent that lacks any former process-related memory and has a memory of the final predetermined diameter.
