The Many Uses of Parylene Conformal Coating in Healthcare
Conformal coating is commonly associated with electronics, but it also is used on a variety of medical devices and instruments. Some of this equipment is electronic as well. This type of protective coating has significant advantages for patients.

Manufacturers of medical instruments have increasingly made them smaller so that patients can undergo surgical procedures with minimally sized incisions. Parylene conformal coatings are extremely thin and durable, making them ideal for this use. The material is biocompatible with the human body and does not degrade. The coatings are stable in temperatures inside the body and in the medical environment. They are not vulnerable to moisture or to chemicals used in medicine.
Parylene has been used in medical device manufacturing for about three decades as of 2020. A broad range of applications are common for this coating in medical usage.
In cardiology, Parylene coatings are applied to implantable devices like pacemakers and defibrillators. These are electronic products that are placed by surgeons to regulate the patient’s heart rhythm.
Cardiac stents coated with Parylene prevent arteries from collapsing after certain procedures. A more recent development is the coating of these stents with a pharmaceutical agent that prevents scarring after these cardiac procedures. Scarring causes narrowing of the arteries.
Hearing and Orthopedics
The material also is used by manufacturers of cochlear ear implants that boost a person’s ability to hear. This is another example of electronic products that have important uses in healthcare. The protective coating is essential because the interior part of the ear is caustic enough to damage delicate electronics. Prosthetic devices that replace limbs and appendages also are coated during the manufacturing process. The same is true for orthopedic devices like bone pins.
Numerous types of medical equipment not intended for implantation or regular long-term wearing is coated for the protection of patients and the longevity of the instruments. Examples include injection needles, catheters, and cannulae. Catheters and cannulae both can be used to drain fluid from the body and supply liquid medication intravenously.
