The Medical Device Regulation (MDR) replaced the Medical Device Directive (MDD) in 2017, marking a significant shift in the regulatory landscape for medical devices in the European Union (EU). While both aimed to ensure the safety and effectiveness of medical devices, the MDR introduced substantial changes to enhance patient protection and address emerging challenges.

Key Differences Between MDR and MDD

• Risk-based classification: Both MDR and MDD classified medical devices based on risk, but the MDR adopted a more refined classification system with stricter criteria. This means that more devices are subject to higher levels of scrutiny.
• Clinical evaluation: The MDR places a greater emphasis on clinical evidence. Manufacturers must conduct more rigorous clinical evaluations to demonstrate the safety and performance of their devices.
• Unique Device Identification (UDI): The MDR mandates the use of UDIs for all medical devices, enabling better traceability and post-market surveillance.
• Post-market surveillance: The MDR strengthens post-market surveillance requirements, including more detailed reporting of adverse events and clinical performance studies.
• Notified Bodies: The MDR introduced stricter requirements for Notified Bodies, the organizations responsible for assessing and certifying medical devices.
• Economic operators: The MDR clarifies the responsibilities of economic operators, including importers and distributors, in the supply chain.

These are just some of the key differences between the MDR and the MDD. The MDR represents a significant step forward in medical device regulation, with the ultimate goal of improving patient safety and public health.
