  • Publication number: 20150018431
    Abstract: In one aspect, the present disclosure pertains to lubricous coating compositions that comprise (a) a higher molecular weight polyvinylpyrrolidone, (b) a lower molecular weight polyvinylpyrrolidone, and (c) a polyfunctional unsaturated crosslinking agent. In some embodiments, such lubricous coating compositions are present in crosslinked form on the surface of a medical article. In some embodiments, the lubricous coating compositions further comprise a solvent, in which case such compositions may be, for example, applied to a substrate in the form of a layer and subsequently crosslinked, thereby forming a lubricious coating on the substrate. In another aspect, the present disclosure is directed to methods for forming various medical articles.
