Abstract
Biocompatible surfaces on medical devices, particularly those formed of synthetic materials, are produced by providing coating compounds having crosslinked regions capable of entrapping biocompatible molecules on the surfaces of medical devices in order to form a stable base layer. The crosslinked base layer is lubricious and is able to function as an entrapping or coupling site for additional biocompatible agents, which agents may be stably incorporated into its crosslinked lattice. Thus, the coatings of the present invention have enhanced lubricity and may also have antimicrobial, protein-repelling, and/or antithrombotic properties. The present invention thus discloses novel, stable, biocompatible coating compositions, devices coated with the compositions of the present invention, methods of making and applying such compounds, and methods of preparing and using devices and apparatus coated with such compositions.
