When it comes to getting a medical device approved for market, there are two main routes manufacturers can take: premarket approval (PMA) or premarket notification (510(k)). Both are regulated by the Food and Drug Administration (FDA), but they have different requirements and different levels of scrutiny. In this article, we will explain the key differences between PMA and 510(k) and how to determine which one is the right path for your device.
PMA: Premarket Approval
PMA is the most stringent type of premarket review and is required for medical devices that are considered high-risk, or Class III, by the FDA. These devices include, but are not limited to:
- Implantable devices such as heart valves, pacemakers, and artificial joints
- Life-sustaining or life-supporting devices such as ventilators and dialysis machines
- Devices that are intended to be used in supporting or sustaining human life and that present potential, unreasonable risk of illness or injury
To get a device approved through the PMA process, a manufacturer must provide scientific evidence that the device is safe and effective, and that its benefits outweigh any potential risks. This evidence is typically collected through clinical trials, and the PMA application must include a detailed description of the device, the clinical data collected, and a comprehensive risk-benefit analysis.
510(k): Premarket Notification
Premarket Notification (510(k)) is a less stringent type of premarket review and is required for medical devices that are considered low-risk, or Class I and II, by the FDA. To get a device approved through the 510(k) process, a manufacturer must demonstrate that the device is substantially equivalent to a device that is already on the market, known as the predicate device.
Determining the Right Path
The decision of whether to pursue PMA or 510(k) approval for a medical device depends on the specific characteristics and intended use of the device. Manufacturers can determine the appropriate classification for their devices by reviewing the FDA’s classification regulations and guidance documents. They can also seek advice from the FDA during the pre-submission process.

PMA is the most stringent type of premarket review and is required for high-risk medical devices, while 510(k) is a less stringent type of premarket review
