What is typically required for a device to be considered "substantially equivalent" in a 510(k) submission?

For a device to be considered "substantially equivalent" in a 510(k) submission, it is essential that the device shares the same intended use and technological characteristics as a predicate device. Substantial equivalence is a key standard in the regulatory process overseen by the FDA, allowing new devices to demonstrate that they do not introduce new safety or efficacy issues compared to existing devices on the market.

The concept of intended use refers to the purpose for which the device is being used, whether for diagnosis, treatment, or other medical functions. Technological characteristics relate to the design features, energy source, materials used, and other physical aspects that determine how the device functions. By ensuring that these elements are comparable with those of a predicate device, manufacturers can demonstrate that the new device is as safe and effective as the existing one, facilitating its approval for market entry.

In contrast, simply being cheaper or having more features does not inherently address the device's safety or effectiveness compared to a predicate. Additionally, the duration a device has been on the market does not factor into the determination of substantial equivalence. Thus, having the same intended use and technological characteristics is crucial in the evaluation process for 510(k) submissions.
