With recent technological advances, there has been an increased emphasis on implantable biomedical devices with increased useful lifetimes, patient compatibility and performance. The BRAIN Initiative, launched in 2013 as the result of many advances in the understanding of neurological systems, has continued to improve our understanding of the human brain. The knowledge gained now allows the restoration of some physical functions after catastrophic injury. Within this realm, there are many applications for vacuum deposited coatings on electrodes. In general, coatings at the interface between an implanted medical device and the hosting biological system can improve device biocompatibility, performance and longevity. Example applications include hard coatings for artificial joints, x-ray opaque coatings to assist in device positioning, bactericidal coatings, and coatings on diagnostic devices.

In this half-day course, a broad overview of biomedically relevant coatings will be introduced including the market outlook for general groups of coatings. Coatings for specific applications will be discussed emphasizing the property that is exploited and the deposition conditions that are known to be important for best performing materials. This course is designed to provide an overview of biomedical coatings for those new to this area of research while providing a background intended to stimulate new ideas for devices.
