MEDICAL TRACEABILITY
FDA-required unique device identifier (UDI) designed for electronic identification and to provide information to consumers. In the human-readable part, the left part (Global Trade Item Number or GTIN) is a static device identifier code for a product. The remainder of the code, the production identifier, may be comprised of the expiration date, lot number, and serial number
and infrared picosecond lasers. Te right choice is dictated by the material,
surface finish, and speed of the required mark. ‘For example, the fibre laser marker can be used on 300 series stainless, and some 17-4 steels; however, as the material and surface finish increase in difficulty and cycle times, nanosecond UV, and picosecond IR solutions might be the best choice,’ said Boyle. Indeed, laser marking on plastic materials,
without the use of chemical additives, has always posed a challenge. Many medical device manufacturers shy away from added chemicals that can affect the performance of
their devices and have possible adverse health effects. Te introduction of UV lasers has helped to address this limitation by producing clearly visible marks, without the need for additive chemicals.
Future wavelengths Laser systems have increased their role in meeting medical device traceability requirements, and it can be easy to forget their already-prominent role in the medical industry for welding, cutting, and additive manufacturing. For example, TLM-Laser supports laser additive printing for bone

implants and laser micromachining for coronary stents. Most recently, Amada Miyachi has worked
with leading medical device manufacturers on advanced processing of their parts with the same laser used for marking. Tis includes cutting or trimming of stainless steel tubes, surface roughening of implantable devices for increased adhesion, and laser welding of small components of various metals. With advances in machine vision and laser
technology, further efforts toward system integration are poised to add new value and ease of production to medical devices.
