Abstract
The present invention provides a coated medical device including a biocompatible coating. The biocompatible coating includes a phenolic resin and at least one particulate material dispersed within the resin that affects a functional property of the coating. For example, the particulate material may affect surface properties of the coating, such as lubricity, sorption and surface area. The biocompatible coating of the present invention is biocompatible and adheres well to a variety of medical devices. The biocompatible coating may be enhanced by the incorporation of lubricants or bioactive agents into or onto the coating.
