How a Coating Keeps Medical Devices Safe and Efficient

Tool manufacturers in every industry need to meet safety and quality standards, but companies that create medical devices face especially rigid scrutiny. The medical community demand functional, affordable products that meet unique safety levels. Medical equipment also has to be biocompatible and provide sanitary features not found in any other industry.

With that in mind, buyers such as doctors and hospitals are always searching for additional information about the latest advances in medical device coatings. Medical coatings like Parylene are added to a wide range of tools to make them safer and more effective.

Why Devices Need Coatings

Different medical tools and appliances need coatings for various reasons. For example, coatings increase the lubricity of devices used during surgical procedures. The coating also selectively provides electrical insulation. Coatings can give an implanted device a biocompatible barrier and lubricate a hypodermic needle. The specialty film that is added to devices during manufacturing may be applied in thin layers that remain free of pinholes.

Benefits of Parylene Coatings

Millions of medical devices are protected using a very thin, vacuum deposited polymer called Parylene. It can be applied to a variety of materials that include glass, plastics, metals, silicone rubber, and ceramics. A clear coating can adhere to any shape, including those with sharp edges. Parylene creates a surface that prevents the growth of bacteria and other types of pathogens. Coatings are biologically stable, FDA approved, non-toxic, and fungal resistant. They also resist chemical attacks from acids, organic solvents, and inorganic reagents.

Parylene Is Used to Protect a Range of Devices

Because it is so adaptable, Parylene is has been adapted for use on a variety of medical tools. It is commonly found on catheters as well as medical coils, seals, and elastomers. Pacemakers and other implants are coated to make them safer and more biocompatible. Parylene is added to hearing aids, mandrels, stents, and electrosurgical instruments.

Thousands of devices are used in medicine and every one of them must remain sanitary and functional. To achieve that result, most tools are coated with a specially formulated polymer. A specialty coating like Parylene is commonly used because it adheres to devices made of virtually any material and shape.
