Abstract

The present invention is directed to a method for coating a surface of a medical device with a coating composition. The method involves chilling the surface to be coated to below the freezing point of at least one solvent contained in the composition. This coating composition is applied to the chilled surface, and a portion of the coating composition is allowed to freeze onto the surface. The surface can then be heated (either by the application of heat from an external source, by allowing to heat by ambient air) to above the freezing point of the solvent in the coating composition to allow the solvent to thaw and be removed, thereby forming a smooth, uniform coating on the surface of the medical device.
