FDA has published a guidance, *Referencing the Definition of “Device” in the Federal Food, Drug, and Cosmetic Act in Guidance, Regulatory Documents, Communications, and Other Public Documents*, to promote clarity regarding references to the terms “device” and “counterfeit device.” The [document](https://www.fda.gov/regulatory-information/search-fda-guidance-documents/referencing-definition-device-federal-food-drug-and-cosmetic-act-guidance-regulatory-documents?utm%5Fmedium=email&utm%5Fsource=govdelivery) says the Safeguarding Therapeutics Act redesignated the definition of “device” without changing the definition, and added a definition of “counterfeit device.”
