Regulation (EU) 2017/745 (MDR) is the legal framework that governs all medical devices placed on the European market today. Fully applicable since 26 May 2021, it replaced Directive 93/42/EEC (MDD), introducing significantly more stringent requirements in terms of safety, performance, quality and transparency.
The MDR’s objective is as straightforward as it is ambitious: to ensure that only devices that are safe, traceable and supported by appropriate clinical evidence reach patients.

The MDR represents a deep and structural reform. Key changes include:

✔️ Stricter requirements for technical documentation
Technical documentation must clearly demonstrate the device’s safety, performance and effectiveness, supported by robust scientific and clinical data.

Many devices previously considered “low risk” must now undergo notified body assessment in order to obtain CE marking.

✔️ ✅ Strengthened post-market surveillance (PMS)
Manufacturers must actively monitor the device throughout its life cycle through PMS, PMCF and periodic assessments (PSUR).

✔️ Enhanced traceability (UDI)
Each device must have a Unique Device Identifier (UDI) to ensure traceability across the entire supply chain

✔️ Introduction of the PRRC
Each manufacturer, authorised representative or importer must have a Person Responsible for Regulatory Compliance (PRRC)—a mandatory role with demonstrated, appropriate competence.
