Thin film coatings are becoming ubiquitous in the medical device industry. Capabilities of medical devices and implants are greatly enhanced by thin films, which impart different properties such as adhesion, wear resistance, corrosion resistance, lubricity, radiopacity, electrical insulation, and bio response. Thin film deposition processes for medical devices are often challenging due to the complex substrate geometry of the components and the requirement for biocompatibility. In biomedical thin film coatings, the shape of a surface controls its interaction with biological components. Optimizing the interactions that occur at the surface of implanted biomaterials will be the key to further advances in this field. Furthermore, as treatment options shift towards non-invasive methods, and device size is reduced, researchers will need to work towards overcoming technological challenges to leverage thin film technology in medical devices. This talk will provide current examples of thin film coating applications in the medical device industry along with the future opportunties.
