Abstract
Microbe-resistant medical devices and methods of making these medical devices are provided. A base coat is applied to at least a portion of a surface of the device. That base coat includes one or more types of antimicrobial particles that are held in the base coat. A polymeric over coat is applied over at least a portion of the base coat. The over coat may be an organic soluble polymer, a water soluble polymer, a hydrogel or any other polymer capable of being coated onto a medical device. The polymer of the over coat is dissolvable in a solvent that does not dissolve the polymeric base coat during application of the over coat. The over coat remains free of the antimicrobial particles by not dissolving the base coat during the over coating process.
