What does the term "predicate device" mean?

The term "predicate device" refers specifically to a device that is legally marketed and used as a benchmark for comparison in a 510(k) submission. This is an important concept in the regulatory process, particularly in the context of the Food and Drug Administration (FDA) submissions in the United States.

When a manufacturer intends to market a new device, they can demonstrate that their device is substantially equivalent to an existing device already on the market—that is, the predicate device. The predicate device must have been previously cleared by the FDA, thus allowing the new device to rely on the established safety and effectiveness data associated with the predicate.

This approach streamlines the regulatory process, enabling faster approval for devices that are similar to ones already available, encouraging innovation while maintaining safety standards for consumers. The comparison with the predicate device allows the manufacturer to highlight similarities and justify the new device’s intended use, design, performance, and safety profile. Understanding this concept is crucial for navigating the regulatory landscape efficiently.
