How To Navigate Clinical Data Per EU MDR By Matthias Fink, MD, TÜV SÜD America In May 2017, the European Medical Devices Regulation (MDR) 2017/745 was published to replace the current Medical Device Directive (MDD) and the Active Implantable Medical Device Directive (AIMDD). In April 2020, the European Parliament adopted the European Commission’s proposal to postpone the Date of Application (DoA) of the MDR by one year, and as such, the new DoA is May 26, 2021. It is worth noting that the end of the transition period for MDD and AIMDD certificates remains May 26, 2024, thus reducing the timeline for manufacturers to get their MDR certificates from four to three years.
