Abstract
An implantable medical device including a plurality of components on a substrate, and a biocompatible multi-layer coating applied by vapor deposition to conform to and sealingly cover at least a portion of the components and/or the substrate. The coating is applied in at least two sets, each set having first, second and third layers. At least one of the first, second and third layers consist essentially of a polymer such as parylene and at least one of the other two layers of the set consist essentially of inorganic material such that each layer differs in at least one diffusion barrier property from the other layers in the set and adds to an overall barrier effect of the coating.
