Technical File Compilation: Ensuring Regulatory Compliance for Medical Devices
Compiling a technical file is a crucial step in gaining market approval for medical devices
A medical device technical file is the complete regulatory dossier that demonstrates a device is safe, performs as intended, and meets all applicable requirements under the relevant regulation — EU MDR 2017/745, UKCA, or FDA requirements. It must be compiled before market placement, maintained throughout the device lifetime, and made available to competent authorities on request. Under EU MDR, the technical documentation requirements are defined in Annexes II and III and are significantly more demanding than under the predecessor MDD.
What is a Technical File?
A technical file contains all necessary information about a medical device, demonstrating compliance with regulatory requirements. It typically includes:
- Device Description & Intended Use – Clear details about how the device works and its purpose.
- Risk Management & Safety Data – Hazard analysis and risk mitigation strategies.
- Design & Manufacturing Information – Materials, specifications, and production processes.
- Performance & Clinical Evaluation – Clinical trial data and real-world performance assessments.
- Quality Management System (QMS) Compliance – Conformance with ISO 13485 and Good Manufacturing Practices (GMP).
Why is Technical File Compilation Important?
A well-prepared technical file ensures:
- Faster regulatory approvals and smoother market entry.
- Compliance with global standards, avoiding legal and financial risks.
- Efficient audits and inspections by regulatory authorities.

Frequently Asked Questions
What must a technical file contain under EU MDR?
Under EU MDR Annex II, a technical file must include: device description and specification; design and manufacturing information; general safety and performance requirements; benefit-risk analysis and risk management (ISO 14971); product verification and validation; clinical evaluation (CER); post-market surveillance plan; and labelling and instructions for use. Annex III covers post-market surveillance documentation.
Who is responsible for maintaining the technical file?
The legal manufacturer is ultimately responsible. Day-to-day maintenance is typically overseen by the PRRC (Person Responsible for Regulatory Compliance) or the designated regulatory affairs function. For outsourced PRRC arrangements — such as those provided by Advena Medical — the PRRC reviews and signs off on technical documentation updates.
How long must a medical device technical file be kept?
Under EU MDR, technical documentation must be kept for a minimum of 10 years after the last device covered by the documentation was placed on the market. For implantable devices, this period extends to 15 years.
Is a technical file the same as a Design Dossier or Technical Documentation?
These terms are often used interchangeably, but strictly speaking: the Technical File was the term used under the old MDD, while EU MDR uses Technical Documentation. The structure and content requirements under EU MDR (Annexes II and III) are significantly more detailed than the MDD equivalent.
