MDR: An Essential Guide for 2021

We published our first essential guide to MDR in 2020. Since then, the new MDR regulation has been introduced. This updated essential guide for 2021 provides a fresh outlook on the challenges surrounding MDR.

Acorn Regulatory has been at the forefront of the MDR issue. The Essential Guide to MDR looks at the issue from a range of perspectives. Our expert MDR team has also written several whitepapers on the issue and they can be accessed here.

The  application of the new MDR regulation on 26th May 2021 has brought about increased responsibility and changes in the medical devices sector. The pressure among stakeholders whether they be economic operators, notified bodies or competent authorities to adjust to these changes has been intense.

We hope that you find this revised essential guide to be useful.
