Technical Documentation for Medical Devices

Before a Medical Device can be placed on the European market, it must meet specific regulatory requirements. Central to this approval process is the Technical Documentation, a structured and comprehensive set of documents that demonstrate the safety, performance, and regulatory compliance of the product throughout its entire life cycle.

WQS has been supporting manufacturers since 1993 in the creation, updating, and conformity assessment of technical documentation in accordance with Annexes II and III of Regulation (EU) 2017/745.

What is technical documentation under the EU MDR?

The Technical Documentation, also known as the Device Master File or Medical Device File, is a structured record that documents the safety, performance, and conformity of a medical device throughout its entire lifecycle.

According to the EU Medical Device Regulation (MDR, Regulation (EU) 2017/745), Technical Documentation is mandatory for all medical devices, regardless of their risk class. It forms the basis for the conformity assessment procedure and the CE marking.

The content requirements are defined in Annex II and Annex III of the MDR. The associated General Safety and Performance Requirements (GSPR) for product conformity are set out in Annex I of the MDR.

Technical Documentation

What role does technical documentation have in the Conformity Assessment Procedure?

The technical documentation is a central element of the conformity assessment procedure and serves as the communication channel between the manufacturer and the Notified Body. The Notified Body comprehensively reviews the submitted documents and may consult external experts for specific technical or clinical aspects.

A complete, clearly structured, and comprehensible submission significantly accelerates the certification process and avoids costly rounds of additional requests.

How can correct planning help avoid errors?

The final submission of the technical documentation usually takes place at the end of the development process. However, it is often only at this late stage that deficiencies and avoidable expenses are identified. Therefore, it is strongly recommended to involve regulatory experts at an early stage in case of uncertainty.

A well-structured approach helps avoid unnecessary costs, such as incorrectly assumed testing requirements, expensive laboratory analyses, or superfluous validations. Such services are often highly specialized and cost-intensive, which can place a heavy burden on the project budget. This makes it all the more important, especially for projects with limited resources and tight deadlines, to strategically manage the effort and focus on the essential aspects of conformity.

What to do if the Notified Body identifies non-conformities in the technical documentation?

Even carefully prepared technical documentation can trigger additional requirements during an audit. Notified Bodies don’t just review isolated individual documents, they evaluate the entire system for consistency, completeness, and traceability. Non-conformities often arise at interfaces: between the risk management file and the GruSuLa checklist, between the clinical evaluation and the PMS report, between the intended use and the classification protocol.

What matters then is structured resolution within the deadline. For major non-conformities, 15 to 30 days are allowed for the corrective action plan. For minor non-conformities, 60 to 90 days are allowed, although multiple minor deviations combined may be classified as major.

WQS offers consulting services for resolving deviations in the technical documentation of medical devices. We analyze the non-conformity report, prioritize based on severity and regulatory basis, and support the revision of the technical documentation through to formal closure.

MDR Table of Contents and Supporting Documents

Structure of the technical documentation according to Annexes II & III of the MDR

In detail, the Technical Documentation is divided into the following chapters:

Chapter

Description

1 Product description and specifications
2 Information to be provided by the manufacturer
3Design and manufacturing information
4 General Safety and Performance Requirements
5  Risk-benefit analysis and Risk Management 
6 Verification and Validation of the Product
7 Post-Market Surveillance

The table of contents of the TD (FB Table of contents TD) is used for precise referencing of the individual documents in the Technical Documentation. The individual information components of the chapters are explained below.

The product description establishes the regulatory identity of the medical device. It includes:

  • Product list: Product groups, including product design, supplier information, classification, and coding (BUDI-DI); to be used when there is more than one product group
  • Declaration on specific substances: Specific substances (not) used in the products or during manufacturing (medicinal products, tissues or cells of human or animal origin or their derivatives, and nanomaterials)
  • Classification protocol: Classification taking into account the intended use, definition of classification rules, and classification according to Annex VIII of the MDR
  • Declaration of conformity: Issued in accordance with classification (Class I, Class Is/r/m/IIa/b, or Class III)
  • Product description:
    With intended use: General product description including item no., BUDI-DI, (contra)indications, mode of action, coding and classification, as well as product characteristics, application specifications, and labeling
    Without intended use: General product description including item no., BUDI-DI, mode of action, coding and classification, as well as product characteristics and labeling; Review of the Notified Bodies’ requirements for documenting the intended use
  • Product Specification: General product description including classification and coding, tolerances and dimensions, as well as material specifications, description of biological properties, and specific details regarding manufacturing and release (e.g., production conditions, sterilization process, and references to valid VAs and AAs)
  • Raw materials, components, and packaging materials: Description of raw materials in the areas of manufacturing, product, and packaging, including their intended contact with the body (direct contact, indirect contact, no contact) and their specifications
  • Packaging Specification: Description of each packaging level, including material, manufacturer/supplier (including certifications), dimensions, and, if applicable, details on the sealing process and packaging contents
  • Intended Purpose: General product description, including item number, BUDI-DI, (contra)indications, mode of action, and classification, as well as application specifications; Application when using the product description without intended purpose

A properly documented intended purpose is the most common source of non-conformities in audits. WQS reviews your intended purpose for consistency with the classification, the General Requirements for Medical Devices (GruSuLa), and the clinical evaluation.

The instructions for use are a regulatory document in their own right with clear minimum content requirements in accordance with DIN EN 1041 and labeling requirements in accordance with DIN EN ISO 15223-1. They must be available in all official languages of the target markets.

Mandatory documents depending on product type:

  • Reprocessing instructions: Minimum content includes the scope of application of the instructions for use, safety warnings, instructions for cleaning and sterilization, manual pre-cleaning (if applicable), mechanical cleaning and disinfection, packaging and sterilization, as well as disposal instructions; details on the compliant and validated reprocessing process for reusable medical devices in accordance with DIN EN ISO 17664 and VA Reprocessing
  • Assessment of Language Requirements: List of target markets and their language requirements, along with their implementation; preparation for marketing in multiple markets to ensure compliance with the various language requirements for the information to be provided (instructions for use, labeling, and, if applicable, implantation card)
  • Labeling Checklist: Checklist for the labeling of medical devices in the instructions for use, on the sterile packaging if applicable, and on the implantation card if applicable; if labeling on the medical device is not possible due to size constraints, the next higher level of packaging must be labeled; single-use medical devices are also exempt from the requirement to label the product
  • Instructions for use: Minimum content includes the scope of application of the instructions for use, product information, intended use, indications and contraindications, general and safety instructions, application, and, where applicable, instructions and a reference to the reprocessing instructions. Instructions for use in accordance with DIN EN 1041 and labeling in accordance with DIN EN ISO 15223-1 in the languages accepted in the Member States where the product is to be sold (see Assessment of Language Requirements). Instructions for use are exceptionally dispensable for Class I and IIa products if the safe use of these products is guaranteed without instructions for use
  • Implantation Card: Product identification details (name, lot number, UDI, and manufacturer), all warnings and precautions, expected service life, and any other information necessary to ensure safe use; to be provided by the manufacturer for implantable products in the languages accepted in the Member States where the product is to be sold (see Assessment of Language Requirements)

  • Essential Safety and Performance Requirements: Documentation of compliance with the Essential Safety and Performance Requirements according to Annex I of the MDR; evidence of the implementation of the standards in various documents (reports, plans, etc.)
  • List of Standards and Regulations: List of all generally applicable and product-specific standards and regulations with identification number, title, and edition; harmonized standards are to be applied if available; if not applicable, the latest edition

Further information on the Essential Safety and Performance Requirements.

Risk management is not a one-time documentation exercise, but a living, continuously updated document. The risk management file according to EN ISO 14971 includes:

  • Risk management plan: scope, risk acceptance criteria, and responsible persons
  • Risk analysis and assessment: hazard identification, harm scenarios, and risk mitigation measures
  • Benefit-risk analysis: as part of the clinical evaluation and the GruSuLa checklist
  • Risk management report: documentation of residual risks and the final overall assessment

Further information on the risk management dossier for medical devices EN 14971.

The scope of the verification and validation data depends directly on the intended use, the product type, and the risk class. For each product, the applicable tests must be derived from the product-specific standards (see List of Standards and Regulations, Chapter 04). The documentation thus contains results and critical analyses of all verification and validation tests and/or studies conducted to demonstrate the product’s conformity with the MDR and, in particular, the applicable essential safety and performance requirements.

Typical test areas depending on the product type:

  • Medicinal products
  • Biocompatibility
  • CMR substances
  • Electrical safety and EMC
  • Usability
  • Tissues or cells of animal origin
  • Clinical evaluation
  • Combination with other products
  • Measuring function
  • Software
  • Stability and shelf life
  • Sterility
  • Material products

Misjudgments regarding testing requirements (e.g., unnecessary or incorrectly defined laboratory tests) are among the most common avoidable cost traps in documentation preparation. WQS identifies early on which tests are actually required for your specific product before expensive laboratory contracts are awarded.

Post-market surveillance is an integral part of the technical documentation (Annex III MDR) and not an optional appendix. The findings obtained from PMS activities are directly incorporated into the updating of all relevant documents.

Mandatory documents depending on risk class:

DocumentProcedure according to VA PMSRisk Class
PMCF-PlanPlanning the update of the clinical evaluation. Collection and evaluation of clinical data from the use of a CE-marked medical device.All Classes
PMS-PlanThe planning of all activities to collect and review experience with the products in order to determine the need for corrective or preventive actions.All Classes

What applies to the technical documentation for in vitro diagnostic medical devices (IVDR)?

For in vitro diagnostic medical devices (IVD), the requirements of the IVDR (Regulation (EU) 2017/746) apply. The basic structure of the technical documentation is comparable, but with specific differences in classification, performance evaluation, and documentation.

What are the legal requirements for technical documentation?

The content requirements are defined in Annex II and Annex III of the MDR. The documentation must cover at least the following areas:

  • Product description and specifications including variants, accessories, classification, and intended use
  • Manufacturer information such as labeling, packaging, and instructions for use
  • Design and manufacturing information including technical drawings, material specifications, and outsourced processes
  • Checklist of General Safety and Performance Requirements (GSPR) in accordance with harmonized standards or Common Specifications
  • Benefit-Risk Analysis and Risk Management according to EN ISO 14971: as a living, continuously updated document
  • Verification and Validation Data, e.g., regarding clinical evaluation, biocompatibility, electrical safety, usability, and stability
  • Post-Market Surveillance (PMS): Information on market surveillance after placing on the market

The scope and depth of the documentation vary considerably depending on the product type and risk class. High-risk products require significantly more extensive evidence than lower-risk products.

For medical devices authorized outside the European legal framework, different or additional requirements may apply to the technical documentation.
