Abstract
A method for making an insertable or implantable medical device including a lubricous coating on a silicone substrate includes treating the silicone substrate with an atmospheric plasma at about atmospheric pressure, the atmospheric plasma formed from a noble gas; applying a solution directly to the treated silicone substrate, the solution including a thermoplastic polyurethane; and heating the silicone substrate and the applied solution to form the lubricous coating on the silicone substrate.
