This guide breaks down the differences between FDA cleared, approved, registered, certified devices, the De Novo pathway, and the 510(k) premarket notification process.
1. Low-Risk Devices (Class I)
Examples: Bandages, non-electric wheelchairs, certain surgical instruments.
FDA Requirement: Registration
What It Means: Class I devices are considered low-risk and typically do not require premarket review. Instead, manufacturers need to register their establishment and list their devices with the FDA. This registration ensures the FDA is aware of the device and its manufacturer but does not involve a detailed assessment of the device’s safety or efficacy.
Why It Matters: For most Class I devices, registration is sufficient because these products are deemed low-risk and are subject to general controls such as good manufacturing practices. These devices are often simple in design and have a long history of safe use.

2. Moderate-Risk Devices (Class II)
Examples: Infusion pumps, surgical drapes, some diagnostic imaging devices.
FDA Requirement: 510(k) Clearance
What It Means: Class II devices require FDA 510(k) clearance. The 510(k) process involves demonstrating that the new device is substantially equivalent to a legally marketed device (predicate device). This process is less rigorous than FDA approval but still requires proof that the device meets specific safety and performance standards.
How It Works:
- Submission: Manufacturers submit a 510(k) application with data showing their device performs similarly to the predicate device.
- Review: The FDA reviews the submission to ensure that the new device is as safe and effective as the predicate device.
- Clearance: If the FDA determines substantial equivalence, it grants 510(k) clearance, allowing the device to be marketed.
Why It Matters: The 510(k) process is crucial for ensuring that moderate-risk devices meet necessary safety and performance benchmarks. It helps streamline the introduction of devices that are similar to existing ones but may feature new technology or improvements.

3. High-Risk Devices (Class III)
Examples: Implantable pacemakers, artificial hearts, certain high-risk diagnostic tests.
FDA Requirement: FDA Approval
What It Means: Class III devices are subject to the most stringent regulatory controls. The FDA approval process involves a detailed premarket approval (PMA), which includes clinical trials, comprehensive data analysis, and an extensive review by the FDA.
How It Works:
- Submission: Manufacturers provide extensive clinical data and test results to demonstrate the device’s safety and effectiveness.
- Review: The FDA conducts a rigorous review of the submitted data, including clinical trial results.
- Approval: If the device meets the necessary criteria, it receives FDA approval, allowing it to be marketed in the U.S.
Why It Matters: FDA approval is essential for devices that pose significant risks to patient health or are used in life-supporting applications. This rigorous process ensures that high-risk devices are thoroughly vetted for safety and efficacy.

Section 510(k) Premarket Notification
What It Is: The 510(k) premarket notification process is used for Class II devices and is designed to demonstrate that a new device is substantially equivalent to an existing, legally marketed device. Named after Section 510(k) of the Federal Food, Drug, and Cosmetic Act, this pathway is essential for devices that are similar to those already on the market but may have new features or improvements.
How It Works:
- Preparation: Manufacturers prepare a 510(k) submission that includes information on device design, performance, and comparison with the predicate device.
- Submission: The submission is sent to the FDA for review. It must include data showing that the new device is as safe and effective as the predicate device.
- Review: The FDA reviews the submission to verify substantial equivalence. This process focuses on whether the new device performs similarly to the predicate device and meets necessary safety standards.
- Clearance: If the FDA finds the device substantially equivalent, it grants 510(k) clearance, allowing the device to be marketed.
Why It Matters: The 510(k) process is crucial for bringing new devices to market that are similar to existing ones but incorporate new or improved features. It ensures that moderate-risk devices are evaluated for safety and performance while streamlining their introduction to the market.

FDA Certified Devices
What It Is: The term “FDA certified” is often used informally but can be misleading. The FDA does not actually “certify” medical devices. Instead, devices are either cleared or approved by the FDA. The term “certified” may refer to devices that have met regulatory requirements, but it’s not an official designation.
Why It Matters: It’s important to rely on official FDA designations—cleared or approved—rather than the term “certified.” This ensures clarity and accuracy when assessing the regulatory status of a device.

De Novo Pathway
What It Is: The De Novo pathway is a regulatory process for novel devices that are low to moderate risk and do not have a substantially equivalent predecessor. This pathway allows manufacturers to request a new classification for a device that is innovative but doesn’t fit into existing categories.
How It Works:
- Submission: Manufacturers submit a De Novo request, providing evidence that the device is safe and effective.
- Review: The FDA reviews the submission, including data on device performance, safety, and intended use.
- Classification: If the FDA agrees that the device is novel but safe and effective, it grants De Novo classification, creating a new device category for future submissions.
Why It Matters: The De Novo pathway provides a route for innovative devices that do not have direct comparators on the market. It’s essential for bringing new technologies to market that offer significant advancements but don’t fit within existing device categories.

Summary
- Low-Risk Devices (Class I): Require registration with the FDA to ensure compliance with general controls.
- Moderate-Risk Devices (Class II): Need 510(k) clearance to demonstrate substantial equivalence to existing devices.
- High-Risk Devices (Class III): Must obtain FDA approval through a comprehensive review process, including clinical trials.
- 510(k) Premarket Notification: Essential for Class II devices, demonstrating substantial equivalence to a predicate device.
- FDA Certified: Informal term; rely on official FDA designations (cleared or approved) for accuracy.
- De Novo Pathway: For novel devices that do not have a predicate, allowing for new device classifications.
Understanding these designations ensures that you’re using medical devices that meet the necessary safety and efficacy standards. For more detailed information, visit the FDA’s official device classification page and stay informed about the latest regulatory requirements.
By knowing the distinctions between these FDA designations, you can make better-informed decisions about the devices you use in your practice, ensuring safety, compliance, and the best outcomes for your patients.
