Q: What are the EU MDR labeling requirements for medical devices?
A: EU MDR Annex I, Chapter III (GSPR 23) sets out comprehensive labeling requirements. Device labels must include: manufacturer name, trade name, and registered address; device name and model/reference; intended purpose if not obvious; lot/batch number or serial number; manufacturing date and expiry date (where relevant); UDI carrier (DataMatrix or barcode); sterility statement and sterilization method (if sterile); single-use symbol (ISO 7000-1051) if applicable; specific storage/handling conditions; warnings and precautions; CE marking with Notified Body ID number (for class IIa+); and an indication that the Instructions for Use should be consulted. Labels must be durable, legible, and in the official language(s) of the member state(s) of distribution.
Q: What is an Instructions for Use (IFU) for a medical device and when can it be omitted?
A: An IFU is the document accompanying a medical device that provides users with all information necessary for safe and intended use — covering installation, operation, maintenance, contraindications, warnings, and residual risks. Under EU MDR, IFUs are required for most devices. Class I and IIa devices may omit an IFU where safe use without one can be objectively justified and documented in the Technical Documentation (GSPR 23.1(d)). FDA requires adequate labeling under 21 CFR Part 801; inadequate or missing IFU content is among the most frequent 510(k) Additional Information Requests. Electronic IFU (eIFU) is permitted under EU Regulation 207/2012 for certain professional-use devices.
Q: What regulatory symbols are required on EU MDR medical device labels?
A: Medical device labels use standardized symbols governed by ISO 15223-1 to communicate regulatory and safety information concisely across language barriers. Commonly required symbols include: CE marking (Regulation (EC) No 765/2008); manufacturer (factory building icon, ISO 15223-1:7.1); authorized representative; date of manufacture; use-by date; lot number; serial number; do not reuse (ISO 7000-1051); sterile (ISO 15223-1:8.1); keep dry; keep away from heat; fragile; and temperature range indicators. EN ISO 7000 governs graphical symbols. Use of non-standardized symbols requires justification; incorrect symbol use can trigger Notified Body queries during conformity assessment.
Q: What is a Technical Documentation (Technical File) for EU MDR and what must it demonstrate?
A: Technical Documentation (TD) is the comprehensive evidence package that demonstrates a device conforms to EU MDR’s General Safety and Performance Requirements (GSPRs, Annex I). It must include: device description, intended purpose, and labeling; design and manufacturing information; GSPR compliance checklist with justifications for each requirement; risk management file per ISO 14971; verification and validation testing data; clinical evaluation and CER; PMS and PMCF plans; and UDI data. TD must be maintained throughout the device lifecycle, updated with new PMS/PMCF data, and made available to Notified Bodies and Competent Authorities on request. Incomplete TD is a leading cause of CE marking delays.
Q: What is an ISO 14971 Risk Management Report and why is it critical for CE marking?
A: ISO 14971 is the international standard for medical device risk management — covering hazard identification, risk estimation, risk evaluation, risk control, and residual risk assessment across the full device lifecycle. The Risk Management Report summarizes the risk management process applied to a specific device, demonstrates that all foreseeable risks have been identified and reduced to acceptable levels, and concludes on the overall benefit-risk profile. It is referenced throughout the Technical Documentation and CER, and Notified Bodies scrutinize it closely. An inadequate or superficial risk management file is one of the most common reasons for CE marking application queries or refusals.
Q: How does regulatory technical writing for medical devices differ from pharmaceutical regulatory writing?
A: Medical device regulatory writing is engineering- and performance-data driven: it centers on Technical Documentation, CERs, risk management reports (ISO 14971), PMCF plans and reports, PMS reports, PSURs, device-specific labeling (IFU, label), SOPs for QMS (ISO 13485), and regulatory response letters for Notified Body queries. Pharmaceutical regulatory writing is clinically and pharmacologically driven: CSRs (ICH E3), CTD Module 2 summaries, SmPCs, PSURs/PBRERs, RMPs, and health authority responses. Device writers need deep understanding of engineering testing, performance standards (IEC 60601, ISO 10993, IEC 62304), and clinical evidence appraisal for devices — rather than pharmacokinetics, toxicology, and clinical pharmacology familiar to pharma writers.
