Expert Opinion Panels and New Guidance Documents Are Part of the Changing Landscape of MDR 2017/745

Author: Suzanne Broussard, PhD  | February 25, 2022

The European Union (EU) saw 2021 bring important milestones and changes to the implementation of Medical Device Regulation (MDR) 2017/745. Key highlights included compliance dates, expert opinion panels, newly published guidance and standards. 

MDD Grace Period Extension

The original deadline of 26 May 2021 for MDR 2017/745 compliance has come and gone, and many medical device manufacturers with devices granted a CE mark under MDD are taking advantage of the 26 May 2024 grace period to become fully complaint with MDR. As of September 2021, the EU notified bodies had granted only 502 conformity assessment certificates, thus, it is anticipated there will be an extreme bottleneck in 2023 and especially in 2024 due to limited notified body availability as manufacturers scramble to meet the May 2024 deadline.

Action Item: Successful MDR compliance requires time.

Ensure successful compliance with MDR requirements by starting early. Many strategic decisions must be made, gaps identified, technical documents updated and brought into compliance, resources and bandwidth identified and deployed. These efforts require a great deal of time, both in work hours and calendar days.

First Three Expert Panel Opinions Released

Articles 106 and 48(6) of MDR require the European Commission to create expert panels to support the scientific assessment and provide advice in the field of medical devices. 

The first three Expert Panel opinions for MDR were published in 2021.

  1. The first-ever MDR opinion letter was initially published in July 2021 for a dental graft device and spotlighted potential differences that might arise between expert panels and notified bodies. In this case, the expert panel challenged certain aspects of the notified body’s assessment of the manufacturer’s clinical study. The public posting was subsequently taken down at the request of the notified body.
  2. An opinion in the field of circulatory system for the Percutaneous Pulmonary Valve (PPV) and delivery system was published 22 November 2021. The PPV is a self-expanding heart valve designed to replace the native pulmonary heart valve without the need for open-heart surgery.
  3. An opinion in the field of orthopaedics, traumatology, rehabilitation, rheumatology for the group of medical devices (acetabular inserts/cups) that are part of a combination system for Total Hip Replacement was published 9 December 2021.

Many more expert panel opinions are expected in 2022 which manufacturers can leverage for information as they prepare for their devices MDR submissions. Publication of these options provides device manufacturers insights into the thinking behind the evaluation of higher level Class IIb and Class III device in their therapeutic field. While the role of the expert panel is advisory, they were created to play a key role in enforcing the tougher market access rules.

Guidance Documents 

A total of 34 guidance documents were published or updated in 2021, bringing the total of MDCG-endorsed and other guidance documents to 90.  Updates ranged from Substantial Modification of Clinical Investigation Under Medical Device Regulation (MDCG 2021-28) to Helsinki Procedure for Borderline and Classification Under MDR & IVDR (Helsinki Procedure).
