A tube suitable for use in a stent is disclosed, comprising a polymeric material having a wall thickness between 75 and 150 microns. Optionally, the tube has a tensile modulus from 2500 to 6000 MPa and a tensile yield strength from 90 to 600 MPa. Preferably the polymer is bioresorbable or biodegradable and the breakdown products are biocompatible. The polymeric material may been orientated by die drawing with a mandrel or die such that it is orientated in the axial and radial directions of the tube. Also disclosed is a method of producing a tube suitable for a stent. An orientable thermoplastic polymer tubing is deformed by drawing it over a mandrel 3 and/or through a die 5. A drawing mechanism 6 applies a drawing tension to the tubing, said tension being insufficient to cause tensile failure but sufficient to deform the tubing. The tube is thereby drawn over a mandrel 3 or through a die 5 to induce uniaxial or biaxial orientation of the polymer. The deformed tubing is then collected from the exit end/side of the mandrel 3 or die 5.
