Bioresorbable polymeric tubes suitable for use in a stent have been produced by a using a die drawing technique , comprising: deforming an orientable, thermoplastic polymer tubing (4) in the solid phase by drawing it over a mandrel (1) and/or through a die (3) , where the mandrel (1) has a lead end and an exit end and the die (3) has an entry side and an exit side , wherein a drawing mechanism applies a drawing tension to the tubing (4) from the exit end of the mandrel (1) and/or the exit side of the die (3), said tension being insufficient to cause tensile failure of the tubing but sufficient to deform the tubing , thereby drawing the tubing over the mandrel (1) and/or through the die (3) in the solid phase to induce uniaxial or biaxial orientation of the polymer； and - collecting the deformed tubing from the exit end of the mandrel (1) and/or the exit side of the die (3).
