Abstract
Medical articles include a tube prepared from a polymer composition containing one or more extractable components. At least a portion of the exterior surface of the tube contains an anti-microbial layer. A transparent vapor-deposited coating of a barrier polymer derived from at least one ethylenically unsaturated monomer covers the exterior surface of the tube. The barrier coating reduces the extraction of extractable component(s) from the tube, but permits the anti-microbial to pass through the barrier layer and provide anti-microbial activity on the barrier surface.
