“A TUBULAR STENT COMPRISING A BIOCOMPATIBLE POLYMER”

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.
