  • positioning a stent on a gear, the gear being supported by a mandrel and having a diameter greater than a diameter of the mandrel;

    rotating the mandrel to cause the gear to provide rotational motion to the stent; and

    applying a coating material to the stent;

    wherein an outer surface of the mandrel does not make contact with an inner surface of the stent; and

    wherein the gear has a shape or diameter configured so that a contact area between the gear and stent changes as the stent rotates.
