In simple terms, medical device classification is a system used to categorize medical devices based on their risk, intended use, and other factors. This classification helps regulatory bodies determine the level of control necessary to ensure the device’s safety and effectiveness.

Overview of Regulatory Bodies

When it comes to medical device classification, several key regulatory bodies set the standards that manufacturers must follow. In the United States, the Food and Drug Administration (FDA) oversees the classification of medical devices into three classes based on risk: Class I, II, and III. Each class has specific requirements that must be met before a device can be marketed.

In Europe, the European Union Medical Device Regulation (EU MDR) is responsible for medical device classification. The EU MDR classifies devices into four categories: Class I, IIa, IIb, and III, with Class I being the lowest risk and Class III the highest. Each class has its own set of regulatory requirements designed to ensure patient safety and device efficacy.

By understanding the definitions and purposes set forth by these regulatory bodies, you’ll be better equipped to classify medical devices and ensure your device meets all necessary standards.

Why Classification of Medical Devices Matters
