By September 2024, the Notified Body and the manufacturer must have signed a formal written agreement. Depending on legacy devices classification, MDR transition deadline is May 2026 for Class III custom-made implantable devices, December 2027 for Class III and Class IIb implantable devices (non-WET) and December 2028 for other Class IIb, Class IIa, Class Is and class Im devices. On the same date, up-classified legacy devices (whose Declaration of Conformity was signed by 26 May 2021) now requiring Notified Body involvement must be MDR certified.

Medical Device Regulation (MDR)
The European Medical Device Regulation (MDR) replaced the MDD and the AIMDD and entered into force on 25 May 2017 with 26 May 2021 as date of application.
All legacy devices must be MDR compliant by the end of December 2028.
For detailed information and conditions of applicability of transitional provisions, please refer to the Regulation amending (EU) 2017/745 and (EU) 2017/746 as regards the transitional provisions for certain medical devices and in vitro diagnostic medical devices published in March 2023.
