The CDRH-GUDID-NCIt terminology files provided here support the cooperative efforts of the Centers for Devices and Radiological Health (CDRH) Unique Device Identifcation (UDI) Program and the National Cancer Institute's Thesaurus (NCIt). Within the UDI Rule, FDA has the authority to require submission of key device attributes, along with the device identifier (DI) to the GUDID. All GUDID attributes and lists of values can be found in the CDRH-GUDID-NCIt terminology files.
