Which statement about FDA clearance for medical devices is true?

• A. May be given for devices with substantial equivalence to a known predicate device
• B. Allows the device to be marketed and sold once a Pre-Market Notification has been submitted
• C. May be issued if the device existed in the market prior to 1976
• D. All of the above

Answer: (A)

Understanding how FDA clearance for medical devices is obtained hinges on the 510(k) pathway, which requires substantial equivalence to a predicate device that is already legally marketed in the United States. When a device demonstrates that it is at least as safe and effective as that predicate (even if not an identical copy), the FDA grants clearance, allowing the device to be marketed. This is why the statement about substantial equivalence being the basis for clearance is correct. It reflects the core mechanism by which many moderate-risk devices enter the market. The other statements aren’t accurate descriptions of the clearance process. Marketing cannot occur simply because a Pre-Market Notification has been submitted; clearance must be issued by the FDA after review. Additionally, pre-1976 devices were grandfathered under the 1976 amendments and didn’t require the 510(k) path to continue marketing; their status isn’t described as “issued clearance” based on prior market existence.
