EU MDR implementation guide for medical devices

Medical Device Regulation (MDR)

The European medical device industry is undergoing a transformative phase due to the enactment of the new Medical Device Regulation (EU MDR), which was officially signed on May 26, 2017. Unlike its predecessor, the Medical Devices Directive (MDD), the EU MDR is a regulation, signifying a binding legislative act across all EU member states. This mandates all medical device companies marketing their products in Europe to comply with the new set of standards outlined in the EU MDR.

The enforcement deadline for compliance was May 26, 2021. Post this date, companies failing to adhere to the EU MDR will be prohibited from selling their medical products within the European Union. The extent of the impact brought about by this regulation is substantial and varies based on your designation as an economic operator, be it a manufacturer, importer, authorized representative, or distributor.

This shift aims to bolster the assurance of medical device safety and effectiveness while fostering innovation and competitiveness within the European medical device market. The following guide aims to provide a clear pathway towards achieving compliance with the EU MDR, ensuring a smooth transition for all stakeholders involved.

MDR Implementation Guide:

Embark on a structured journey towards compliance with the new Medical Device Regulation (MDR EU2017/745) through our step-by-step guide. This guide is designed to provide a simplified understanding, aiding in efficient and cost-effective implementation of the new regulation.

Disclaimer: This guide is based on our experiences and should not be taken as professional advice.

Preliminary Step: Engage with your Notified Body:

Confirm if your Notified Body is MDR certified and supports your device scope. Find the list of all MDR-certified Notified Bodies including information on their scope under the following link.

Yes: Schedule your MDR audit date!

No: Transition to a certified Notified Body promptly.

1.) Device Classification:

Review the new MDR rules to ascertain any impact on your current or future product classification. See MDR Annex XIII or use our classification form.

2.) Economic Operators:

Identify your role(s) as an economic operator(s) – Manufacturer, Importer, Distributor, or Authorized Representative, each having distinct MDR requirements.

Utilize our Economic Operators Tool for a clearer understanding of each role and its responsibilities.

3.) Gap Assessment:

Utilize our MDR Gap-Analysis Tool to:

1. Step

Eliminate irrelevant information from the chapters and annexes.

2. Step

Identify and filter out non-applicable keywords.

3. Step

Review all requirements to determine their relevance to your business.

With our MDR Gap-Analysis Tool you are able to do all these steps above and you can reduce the information immediately.

4.) Implementation:

Prior to starting the implementation phase, you should put a plan in place. The steps below will guide you through the main topics. Do not forget to read MDR article 120 (transition period) carefully.

Update of the transition timelines according to the new Regulation (EU) 2023/607:

The main changes are:

EU MDR Transition Timelines (15th March 2023):
-until 31st December 2027 for Class IIb and III
-until 31ste December 2028 for Class I and IIa
-Until 26th May 2026 for Class III Implantable customer-made devices
-Extends validity of certificates issued up to 26 May 2021
-Remove “sell-off” date


These extended transition periods are intended to provide manufacturers with additional time to meet the new requirements of the EU MDR 2017/745. However, it’s important to note that these extensions apply only to certain medical devices, and manufacturers should carefully review the regulation to determine the specific deadlines applicable to their products.

During the transition period, devices that are compliant with the previously applicable Directives (AIMDD, MDD and IVDD) and devices that are compliant with the current Regulations (MDR and IVDR) can co-exist and may simultaneously be placed or made available on the EU market. This is particularly important for those third countries that rely on the CE marking of devices to grant access to their markets.

In conclusion, the transition period and deadlines for the EU MDR 2017/745 are critical aspects that manufacturers must understand and plan for. By doing so, they can ensure a smooth transition to the new regulatory framework, maintain market access, and ultimately ensure the safety and performance of their medical devices.
