    摘要: A stent is positioned on an undersized mandrel and the stent is coated with an excess of a polymer and drug solution. The stent is rotated to spin off the excess of the coating. The stent is then moved into a new, clean position on the mandrel. The process is repeated a few times, after which time the coating is already dry and non-sticky. This process forms a conforming coating. Various important polymer solution parameters include viscosity, solvent evaporation rate and several others. The actual type of coating polymer is not as important as how the surface of the stent is treated, according to the steps described herein.
