MDR Classification of Medical Devices: A Complete EU Guide
Under the EU MDR 2017/745 regulation, correctly classifying your medical device is the first and most critical step toward CE Marking compliance. Classification determines the level of regulatory scrutiny, the involvement of a Notified Body, and the documentation required for market access. Whether your device falls under Class I, IIa, IIb, or III, understanding the rules of Annex VIII is essential for compliance and avoiding costly delays.
At RegHelps, we guide you through accurate MDR classification based on intended use, mode of action, and associated risk ensuring a strong foundation for CE Marking success.
EU MDR Device Risk Classes
Under EU MDR 2017/745, medical devices are classified into four main risk categories: Class I, Is, Ir, Im, IIa, IIb, and III. Classification is based on factors like invasiveness, duration of contact, and the part of the body affected. Devices with higher potential risks require greater regulatory oversight and Notified Body involvement. Understanding the distinction between these classes is critical for preparing the right technical documentation and compliance pathway.
