Legacy Devices (MDD CE marked devices)

Navigating the Transition from MDD to MDR for Legacy Medical Devices

As a notified body reviewer entrusted with ensuring the safety and efficacy of medical devices, it's essential to address the nuances surrounding legacy medical devices under the Medical Device Directive (MDD). These devices, while approved and in use, face a pivotal transition as the medical device landscape evolves towards the Medical Device Regulation (MDR).

Understanding Legacy Medical Devices:

Legacy medical devices refer to products that were placed on the market and granted conformity assessment under the MDD, the regulatory framework that has been the cornerstone of medical device regulation in the European Union (EU) for decades. These devices have been crucial in providing essential healthcare solutions, ranging from simple instruments to complex life-saving technologies.

Under the MDD, legacy devices have undergone conformity assessment procedures to ensure compliance with essential safety and performance requirements. However, with advancements in technology, changes in patient needs, and an evolving regulatory landscape, the European Union has introduced the MDR to enhance patient safety and streamline regulatory processes.

Transitioning to MDR:

The transition from MDD to MDR represents a significant shift in regulatory requirements for medical devices. The MDR introduces stricter criteria for product assessment, post-market surveillance, and transparency. It aims to strengthen patient safety and provide greater confidence in the regulatory system.

For manufacturers of legacy medical devices, navigating this transition is imperative. While MDD certification allowed these devices to be placed on the market, adherence to the MDR is essential to maintain market access within the EU. The transition period provides a window for manufacturers to update their technical documentation, conduct additional testing if necessary, and ensure compliance with MDR requirements.

The Transition Program:

Recognizing the complexity of transitioning legacy devices to MDR compliance, the European Union has established transition programs and guidance documents to assist manufacturers in this process. These programs provide valuable resources, including timelines, checklists, and support from notified bodies, to facilitate a smooth transition.

As a notified body reviewer, our role is to collaborate with manufacturers, offering guidance and expertise to ensure that legacy devices meet MDR requirements. Through comprehensive review processes and adherence to regulatory standards, we strive to uphold the highest levels of safety and efficacy for patients relying on these devices.


Legacy medical devices play a vital role in healthcare delivery, providing solutions that have benefited countless patients over the years. However, as regulatory requirements evolve with the introduction of the MDR, it's essential for manufacturers to navigate the transition process effectively.

By embracing the transition program and working closely with notified bodies, manufacturers can ensure the continued compliance and market access of their legacy devices. Ultimately, this commitment to regulatory excellence contributes to the safety, efficacy, and trustworthiness of medical devices in the European Union.
