11. Can I use a predicate device that has been cleared through a 510(k) submission?

Yes, you can use a predicate device that has been cleared through a 510(k) submission as a reference for demonstrating substantial equivalence to your device.

Substantial equivalence is a key concept in the 510(k) submission process. It means that your device is as safe and effective as a legally marketed device (predicate) and that there are no new risks associated with your device compared to the predicate.

Using a predicate device that has already been cleared through the 510(k) process can streamline your submission, as you can leverage existing data and knowledge about the predicate device to support your own submission.

However, it’s essential to ensure that your device has the same intended use and technological characteristics as the predicate device. This comparison forms the basis for demonstrating substantial equivalence.

When selecting a predicate device, you should also consider factors such as:

  • The device’s indication for use
  • Design features
  • Materials
  • Performance characteristics.

If there are any differences between your device and the predicate, you will need to provide scientific evidence to justify those differences and demonstrate that they do not affect the safety or effectiveness of your device.

Overall, using a predicate device in your 510(k) submission is essential, but it’s important to conduct a thorough comparison and provide comprehensive documentation to support your claim of substantial equivalence.
