摘要：
The present invention relates to a tubular stent comprising a biocompatible polymer wherein the stent is made from (a) dip-coating a mandrel with a solution comprising one or more biocompatible polymers to form a polymer tube at least one of the polymers including an iodinated contrast agent； (b) spin-drying the polymer tube around its longitudinal axis； (c) solvent-polishing and vacuum drying the polymer tube； and (d) necking the polymer tube by drawing the mandrel bearing the polymer tube through one or more necking dies of decreasing diameter wherein said necking is carried out at a temperature above the glass transition temperature of the polymer and below the melting temperature of the polymer.
