  • applying a composition to a stent substrate, the composition including a polymer component and a solvent;

    exposing the polymer component to a temperature equal to or greater than a Tg of the polymer component, wherein the exposing removes solvent from the applied composition,wherein the exposing comprises blowing a heated gas on the polymer component to heat the polymer component to a temperature equal to or greater than the Tg of the polymer component; and

    repeating the applying and exposing one or more times to form a coating, wherein the solvent content of the coating after the final exposing step is at a level suitable for a finished stent.
