Electronics are becoming smaller and smaller every day. The inner workings of electronics, however tiny, still need to be protected. Now imagine how small the inner workings of a medical implantation device are. The best protection for these little electronic pieces is with a parylene conformal coating.
Parylene, unlike other conformal coatings, is deposited in vapor form rather than wet such as dipping, spraying, or brushing. The unique application process allows it to cover the entire area in need of protection. The deposition technique transforms powder parylene into a gaseous form at the molecular level. The vapor format can easily coat an electronic component evenly, creating a durable covering. For this reason, parylene is seen as a superior conformal coating. It does not leave cracks or coat unevenly.
Medical implants are coated in parylene because it is very thin and durable.
Benefits of Parylene for Implants
A parylene conformal coating is applied to an electronic that needs protection from exposure to environmental threats. For an implantable, that means it requires a protective layer that can stand up to water, acid, and other bodily fluids. Parylene is non-toxic and can handle extreme conditions without deteriorating. The uniform coating of parylene allows it to cover implantables of all minuscule sizes.
Types of implants that use parylene are:
- Cochlear implants that require a microphone and improve patient hearing
- Stents that promote blood transmission
- Mechanical constructions that replace hip joints
- Radioactive implants used in chemotherapy
- Sensors for physiological activities
As you can see, these medical implants affect many people and can improve lives daily.
Parylene has all the characteristics that make it a perfect tool for the medical industry. Precision, reliability, strength--this conformal coating has it all. Here's a closer look at how parylene works to protect one of the most complex and crucial tools in the medical world: implantable medical devices.
Why Parylene is the Right Fit
Countless industries rely on parylene for its long list of high-quality characteristics, but the medical industry requires a unique level of perfection. Parylene conformal coating can provide all the characteristics needed to protect devices that will be implanted in the body to save lives. When it comes to medical science, parylene is especially valued for certain features:
- biocompatibility for safety
- precise, pinhole-free coating
- protection against the extreme conditions in the human body
Some of parylene's reliability is thanks to the chemical vapor deposition process by which it is placed on the devices. This makes the coating thin but strong, able to coat even awkward shapes and crevices. Our parylene experts know that thanks to these characteristics, parylene is saving lives.
How Parylene Protects
Sensor implants. Sensor implants work to give data on patient health and medical device success, which means that they need to be placed in various places throughout the body. This is an excellent example of parylene's hard work in the medical industry because this unique coating is able to protect the sensor without interrupting the delicate function, all while being biocompatible and reliable.
Cardiac Assist Devices. There are various types of Cardiac Assist Devices, but they all need to be able to work properly without being corroded by bodily fluids. That's where parylene comes in. This conformal coating provides reliable coverage that seals the device and ensures that both the device itself and the patient are safe (since electrical charges can sometimes come from a Cardiac Assist Device.
Cochlear ear implants. These unique devices help the hearing process--but they also need to be small and powerful. Parylene coatings can be placed thin enough that they don't interrupt the line of delicate sensors on this device, but the protection is strong enough that the conditions inside the ear never interrupt function.
