The nomenclature of medical devices is a coding system used to generically identify medical devices and related health products. Having a nomenclature system in place for medical devices facilitates their management and regulation. This is achieved by standardizing terms that enable communication despite linguistic and other barriers. Several naming systems for medical devices exist and each is used by a different group of professionals. The naming structure depends on the needs of that particular group.Needs such as maintenance, procurement, accounting, stock keeping, regulatory affairs, adverse medical device event reporting, and customs operations are key catagories. The Global Medical Devices Nomenclature System (GMDN) and the Universal Medical Devices Nomenclature System (UMDNS) and the European Medical Device Nomenclature (EMDN) are the primary nomenclature systems being used for medical devices.
