Development and application of physical vapor deposited coatings for medical devices: A review

Physical vapor deposition (PVD) technology can modify the surface properties of equipment without changing the biomechanical properties of the substrate, and has been increasingly used in medical devices. Medical devices can be divided into surgical instruments, implantable medical devices and interventional medical devices according to the object and the way of application. For the defects of different medical devices during use, this paper reviews the development and application of PVD coatings to improve the performance and extend the life of medical devices. Finally, the development of PVD coatings for medical devices is expected.
