Abstract

An implantable electrode has a biomedically compatible, microscopically rough, metal coating that creates a high double-layer capacitance. The coating is applied to the implant by physical vapor deposition. The coating preferably is applied via a generally oblique coating flue or a law energy coating flux. In some embodiments, the coating has pores. The pores can contain a drug, which can diffuse over a period of time. The coating may be partially nonporous to protect the implant from corrosion.
