Medical Device Technical Documentation for MDR: CE Marking Compliance Guide
Compiling Medical Device Technical Documentation for MDR is a mandatory prerequisite for placing any medical device on the European Union market. Under the European Union Medical Device Regulation (EU MDR 2017/745), technical dossiers require significantly more clinical data, risk management, and post-market tracking than the previous Medical Device Directive (MDD 93/42/EEC).
Whether you are seeking initial CE marking certification or updating technical files for legacy products, maintaining an audit-ready technical dossier is essential to demonstrate compliance with general safety and performance standards.

What is Medical Device Technical Documentation for MDR?
Medical Device Technical Documentation for MDR is a comprehensive set of technical dossiers, testing evidence, and clinical records that prove a device conforms to Regulation (EU) 2017/745. Governed primarily by Article 10(4), Annex II, and Annex III of the MDR, this documentation establishes that the medical device is safe, effective, and performs as intended throughout its entire lifecycle.
Why EU MDR Compliance Demands Higher Standards
Unlike the legacy MDD framework, the EU MDR requires continuous lifecycle management rather than a static technical file. Manufacturers must continuously update their technical documentation with real-world clinical performance data, post-market surveillance (PMS) findings, and risk-benefit re-evaluations.
For active diagnostic devices—such as multi-parameter vital signs devices or cardiac diagnostic tools like blood pressure monitors—technical documentation must also include rigorous software validation (EN 62304), electrical safety testing (IEC 60601-1), and electromagnetic compatibility (EMC) reports.
Core Structure: Annex II vs. Annex III Technical Documentation
Under EU MDR 2017/745, technical documentation is divided into two primary structural sections:
| Regulation Section | Scope & Requirements | Key Elements |
| Annex II: Technical Documentation | Pre-market design, manufacturing specs, verification, and clinical evidence. | Device description, GSPR checklist, risk management file, software documentation, and clinical evaluation report (CER). |
| Annex III: Technical Documentation on PMS | Post-market lifecycle tracking, real-world data, and continuous monitoring. | Post-Market Surveillance (PMS) Plan, PMCF Plan, Periodic Safety Update Report (PSUR), or PMS Report. |
Key Components of an MDR Technical Dossier
A fully compliant Medical Device Technical Documentation for MDR file must follow a logical, searchable format (often aligned with the STED – Summary Technical Documentation structure). The primary elements include:
1. Device Description and Specification (Annex II, Section 1)
Basic UDI-DI assignment, intended purpose, target patient population, and indication for use.
Detailed product classification rationale under MDR Annex VIII rules.
Configurations, variants, accessories, and system components.
2. Information Supplied by the Manufacturer (Annex II, Section 2)
Product labels in official languages of target EU Member States.
Instructions for Use (IFU), packaging specifications, and single-use/reusable warnings.
3. Design and Manufacturing Information (Annex II, Section 3)
Complete manufacturing process workflows, critical process validations, and environmental controls.
Identification of all manufacturing sites, key component suppliers, and subcontractor facilities.
4. General Safety and Performance Requirements (GSPR) (Annex I & Annex II, Section 4)
A comprehensive GSPR checklist cross-referencing harmonized standards and Common Specifications (CS) applied.
Precise identity of test reports and verification documents proving conformity to each applicable GSPR.
5. Benefit-Risk Analysis and Risk Management (Annex II, Section 5)
Risk management plan, risk analysis methods (e.g., ISO 14971 FMEA, HAZOP), and risk management report.
Documented overall benefit-risk acceptability analysis.
6. Product Verification and Validation (Annex II, Section 6)
Biocompatibility: ISO 10993 testing data evaluating biological safety.
Sterilization & Shelf Life: Validation reports for EtO, Gamma, or Steam sterilization processes and accelerated/real-time aging studies.
Clinical Evaluation: Clinical Evaluation Plan (CEP) and Clinical Evaluation Report (CER) compiled according to MDCG guidelines.

Notified Body Review & Technical File Maintenance
Unless a device is Class I (non-sterile, non-measuring, and non-reusable surgical instrument), the technical documentation must be reviewed and audited by a accredited Notified Body prior to issuing a CE compliance certificate.
File Maintenance and Retention Requirements
Retention Timeline: Manufacturers or their Authorized Representatives (EC REP) must keep technical documentation accessible to Competent Authorities for at least 10 years after the last device is placed on the market (and 15 years for implantable devices).
Location: Non-EU manufacturers must ensure a complete copy of the technical dossier is securely maintained by their designated EU Authorized Representative.
Change Control: Any significant change to device design, materials, manufacturing site, or intended use requires formal updating of the technical documentation and prior approval from the Notified Body.

FAQ's
What is the difference between Annex II and Annex III in EU MDR?
Annex II covers pre-market technical data (design, testing, GSPR), while Annex III specifies post-market surveillance (PMS) plans and continuous safety reports.
Is a technical file required for Class I medical devices under MDR?
Yes, all medical devices regardless of class require technical documentation, though non-sterile Class I files do not undergo prior Notified Body audit.
How long must MDR technical documentation be retained?
Technical documentation must be kept for at least 10 years after the last product release, or 15 years for implantable devices.
What is the GSPR checklist in MDR technical documentation?
The GSPR (General Safety and Performance Requirements) checklist proves device conformity to Annex I safety requirements using specific standards and test reports.
What format is recommended for MDR technical documentation?
Manufacturers commonly use the STED (Summary Technical Documentation) or MDCG-aligned technical dossier format structured around Annexes II and III.
