Polymeric Confonnal Coatings for Implantable Electronic Devices

Long-term implantable devices such as cardiac pacemakers are protected from corrosive tissue fluids by means of a metallic, hermetically sealed enclosure. When the electronic circuitry contacts infiltrating tissue fluids due to a corrosive breach in the hermeticity, failure of the device is almost immediate. Polymeric coatings have been investigated to serve as a secondary moisture barrier in this work.
