The MDR and IVDR Have Been Published blog

Publication in the Official Journal of the European Journal on May 5, 2017 means the regulations will enter into force on May 26, 2017, twenty days after publication. We will have a three-year transition period for the MDR and a five-year transition period for the IVDR. Products can be issued a certificate under the MDD with a full five-year expiry for the first two years of the transition period but should comply with all other aspects of the MDR in May, 2020. Since most IVD products are currently on the market as a self-certified they will require certificates by the end of the five-year transition period where most products now require Notified Body involvement.  

Although there are some pending implementing and delegating acts that will help to bring clarity to the requirements in the MDR and IVDR, you should be assessing the impact to your products and developing your implementation plans. It is not too early to start engaging your key stakeholders including your Notified Body, authorized representatives, and clinical support resources to ensure you have the proper resources to support the transition.

Here's a link to the official publication and below is an outline of key dates.
