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.
L'invention concerne des dispositifs médicaux résistants aux microbes et des procédés permettant de les produire. Une couche de base est appliquée sur au moins une partie d'une surface dudit dispositif. Cette couche de base comprend au moins un type de particules antimicrobiennes, retenues dans la couche de base. Une couche supérieure polymère est appliquée sur au moins une partie de la couche de base. La couche supérieure peut être un polymère organique soluble, un polymère hydrosoluble, un hydrogel ou tout autre polymère apte à être appliqué sur un dispositif médical. Le polymère de la couche supérieure est soluble dans un solvant qui ne dissout pas la couche de base polymère pendant l'application de la couche supérieure. Ladite couche supérieure demeure exempte de particules antimicrobiennes par non dissolution de la couche de base pendant le processus d'application de la couche supérieure.
