Abstract
The role of polymers in medical devices continues to grow rapidly due to increasing demand for more reliable products and advances in other technical fields. Most medical implants incorporate microelectronic components that are placed inside the body to either sense or to facilitate a physiological response. It is very important that the electronic components do not create an adverse effect within the body. Among the available polymers, Parylenes (vapor phase deposited organic coatings), have played a significant role in packaging and protection of such devices for safety and enhancing the overall electronics reliability within body tissues and fluids. Parylenes have also been very effective on non-implantable medical electronics devices, by providing protection from adverse environmental effects. Examples of Parylenes in medical electronic devices include retinal implants, implantable cardiac defibrillators, neurostimulator pulse generators, RFID implants, transdermal drug delivery devices, digital dental imaging equipment, hearing aids, ingestible sensors/transmitters, and implantable radiation dosimeters. Their suitability and biocompatibilty encourage researchers to explore Parylenes’ role in sensors and in active electronic devices for medical applications. With new advances in the Parylene technology itself and their possible applications in medical electronics, this paper presents an overview of Parylene’s impact on medical electronics and other devices.
