There is a transition period for manufacturers to apply for the new MDR certification for devices currently certified under the Medical Device Directive (MDD) or the Active Implantable Medical Device Directive (AIMDD).
Certificates issued during the transition period under the MDD and AIMDD remain valid for the entire period, unless they exceed four years after the date of application. The validity of MDD and AIMDD certificates after the date of application depends on the compliance with provisions specified in Article 120 (3).
If you do not receive a certification during the transition period and your MDD certificate expires during that time, you must withdraw your products from the EU market until they are certified under the new MDR.
