Abstract

The invention is directed to an ion plasma deposition (IPD) method adapted to coat polymer surfaces with highly adherent antimicrobial films. A controlled ion plasma deposition (IPD) process is used to coat a metal or polymer with a selected metal/metal oxide. Exposing the coated surface to ultraviolet light significantly improves the antimicrobial properties of the deposited coatings.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A medical device comprising:
 a substrate; and
 an antimicrobial coating material on the substrate, wherein the coating material is deposited onto the substrate in a gas-free environment while exposing the material to a light having ultra-violet wavelengths.
