Which statement best describes the predicate device concept in device regulation?

• A. A predicate device is required for all new devices.
• B. A predicate device is used to demonstrate substantial equivalence in the 510(k) pathway.
• C. A predicate device must be identical in all materials.
• D. A predicate device is used only for PMA.

Answer: (B)

In device regulation, the predicate device concept centers on demonstrating substantial equivalence in the 510(k) process. When bringing a new device to market through 510(k), the sponsor identifies a legally marketed predicate device and compares it to the new device. If the new device shares the same intended use and has similar technological characteristics, and there are no new questions of safety or effectiveness, it can be deemed substantially equivalent and cleared. The predicate does not have to be identical in every material aspect; differences are allowed as long as they don’t raise new safety or effectiveness concerns. This approach is specific to the 510(k) pathway and contrasts with PMA, which requires clinical data for high-risk devices. Not every device requires a predicate—some may go through other regulatory routes like de novo when no suitable predicate exists.
