Digital healthcare has seen a tremendous development during past years with implantable electronics being part of ever-increasing number of treatment plans for patients. Consequently, need for advanced medical devices is rapidly expanding with ever tightening requirements as increasing number of complex therapeutic devices are implanted on the most sensitive areas of the body such as brain, spine, heart and eyes.
To ensure long lifetime and to reduce potential side effects in such environment, particular attention needs to be paid to the protective and biocompatible coating providing hermetic sealing, structural integrity and corrosion resistance to protect the device from the detrimental impact due to human body environment and to prevent the device releasing harmful substances to the surrounding tissue. The perfect protective coating therefore needs to be a biocompatible, pinhole-free barrier capable of uniformly coating devices with widely varying sizes and shapes to render them inert towards human body and vice versa, for decades after implantation.
Traditional thick film coating methods such as CVD, PVD or parylene tend to have limited utility on one or more of the requirements above. Atomic Layer Deposition (ALD) technology allows fabrication of ultra-thin, highly uniform and conformal material layers of exact thickness to atomic level and chemical composition on a variety of substrates, including highly temperature-sensitive organic materials. The technology was originally brought into large scale use by the semiconductor industry but has after that been applied to a variety of applications, including the latest MedTech innovations. Using ALD as the coating method for electronical implants improves patient safety as well as ensures longer lifetime and improved reliability for the implant.
Picosun’s ALD solutions have been in production for years at various medical industries including electronical implant protection. The coatings have been tested and proven to be non-cytotoxic, biocompatible, and to have antibacterial or bioactive function.
Join our webinar to learn more how ALD will revolutionize the MedTech industry, especially in the field of electronical implants, and create added value and competitive edge to your products. We will present the latest results on the superior hermeticity of our ALD encapsulants as a protective barrier against human tissue fluid. We have proven results on suppression of bacterial growth and ultra-low levels of bacterial endotoxins, surpassing even the strictest requirements of implant industries.
