FDA 510(k) vs PMA vs De Novo: Which Pathway Fits Your Device?
Picking the right FDA pathway is one of the biggest decisions you’ll make when bringing a medical device to the US market. The three main routes are 510(k), PMA, and De Novo. Each one is built for a different level of risk and a different set of circumstances, so knowing how they differ early on can save you a lot of time and rework later.
How the FDA Thinks About Risk
The FDA regulates devices using a risk-based approach. Which pathway applies to you comes down to three things: your device’s classification, its intended use, and whether a legally marketed predicate device already exists.
The Three Pathways
510(k) Clearance
This is the route for devices that can show they are substantially equivalent to a legally marketed predicate device. In practice, you’ll submit information about your device’s intended use, its technological characteristics, and performance testing that supports the comparison.
Premarket Approval (PMA)
PMA is the FDA’s most rigorous review pathway and is generally used for high-risk Class III devices. Here, you’ll need to provide solid scientific evidence that your device is both safe and effective.
De Novo Classification
If your device is new, low-to-moderate risk, and has no predicate, De Novo is typically the way in. It also lets the FDA create a new Class I or Class II classification based on your device’s risk profile, which can later serve as a predicate for other devices.
How to Choose
When deciding between 510(k), PMA, and De Novo, it helps to ask yourself:
What is my device’s classification and risk level?
Is there a suitable predicate device?
How much clinical evidence will I need?
Which regulatory controls apply?
Looking at submission requirements early helps you avoid delays and gaps in documentation down the road.
