    Abstract: The present invention is a method for the modification of the surfaces of polymeric materials with polymer coatings that may be subsequently treated to be lubricious and anti-microbial. The method comprises incubating a photo-initiator-coated polymeric material with an aqueous monomer that is capable of free radical polymerization and exposing the incubating polymeric material to UV light creating a modified surface on said polymeric material. The method may additionally comprise adding a silver component to the modified surface. The silver component may be provided as a silver salt coating or a silver salt contained within a hydrogel bonded to the acrylate modified polymeric material surface.

    Abstract: Methods for making modified surfaces and in particular, surfaces that may be lubricious and may be further treated to be anti-microbial are disclosed. Devices comprising modified surfaces prepared by the methods are also disclosed. An exemplary method comprises incubating a photo-initiator-coated substrate in an aqueous monomer solution that is capable of free radical polymerization, exposing the incubating substrate to ultraviolet (UV) light creating a modified surface on the substrate. An anti-microbial agent may be added to the modified surface.

    Abstract: The present invention is directed to a vehicle for effecting drug delivery from a solid substrate. Hydrogels loaded with liposomal therapeutic agents such as antibiotics are covalently bonded to the surface of substrates such as in-dwelling medical devices, such as implants, catheters, and the like. The present invention is particularly useful in the treatment and prevention of biofilm mediated infection often associated with the use of in-dwelling medical devices.
