Abstract
The present invention relates to methods of making a prosthesis or a stent with a smooth covering. The method includes providing an elastomeric tube including an inner diameter and an outer diameter, positioning the elastomeric tube in a tube expander including a vacuum, expanding the inner diameter and the outer diameters of the elastomeric tube by applying the vacuum, providing a mandrel, positioning an inner covering over the mandrel, positioning a stent over the inner covering, positioning an outer covering over the stent to form a covered stent, positioning the mandrel and the covered stent in the tube expander, releasing the vacuum, removing the elastomeric tube, the covered stent, and the mandrel form the tube expander, applying pressure and heat to the elastomeric tube, the covered stent, and the mandrel, removing the elastomeric tube, the covered stent, and the mandrel from the pressure and the heat, removing the elastomeric tube from the covered stent, and removing the mandrel from the covered stent.
