The EU Commission published an updated survey on Notified Body certifications and applications: HERE
The survey was conducted at the beginning of April 2023 and had 100% participation from the MDR/IVDR Notified Bodies (39 total).
The purpose of the surveys is to monitor the current, and future, availability of medical devices on the EU market.
For example, the October 2022 Notified Body Survey showed ~23,000 MDD/AIMDD certificates expiring by May 2024. Yet only ~8,000 MDR applications had been filed and only ~2,000 MDR certificates were issued. This was one of the motivating factors for the extension of the MDR transition period.
