Abstract: Biostable packaging, protection and reliability of various medical electronic components and devices (e.g. retinal implants, implantable cardiac defibrillators, neurostimulator pulse generators, RFID implants, equipment, hearing aids, ingestible sensors/transmitters, and implantable radiation dosimeters) are becoming more challenging due to their long-term performance requirements. In addition, bioacceptability of electronic devices becomes more important when they are used within the human body or in direct contact with it. In the recent years, vapor phase polymers, particularly Parylenes, are finding an increasing role in the conformal insulation and biostability of medical electronics and enhancing their overall reliability because of the unique characteristics that are generally not available with other polymeric materials. This paper reviews some recent developments in the Parylene technology, including attributes of a new Parylene type, which offer solutions to many existing and future biostable packaging and reliability challenges for medical electronics. Key words: Parylene, biostable, bioacceptable, biocompatible, medical electronics, conformal coating, medical device.
