Techical Document
The European medical device regulation 2017/745 requires manufacturers to maintain a technical file medical device dossier for their products; this compilation of relevant files must be kept up to date throughout the device’s entire life cycle. It acts as the foundation for conformity assessment and securing the CE mark. When you are getting ready to bring a medical device to market, your technical documentation has to be clear, organized and searchable, so think of this file as your main compliance documentation. This MDR technical documentation needs to tell a straight story about your product and give a clear map tracing everything from the raw materials up to long-term clinical safety performance.
Technical File Medical Device Specifications and Global Traceability
The foundation of your application is how well you define your device because regulators want a clear product or trade name, plus a breakdown of the intended purpose, target users and the specific patient population it treats or diagnoses. You will need to state the medical conditions your device addresses, the exact clinical indications, contra-indications and critical safety warnings.
From a traceability perspective, assigning a Basic UDI-DI is essential as soon as that system is active. If it is not live for your product yet, you must use alternative references such as product codes or catalogue numbers so your device can always be tracked in the field.
Your file also has to explain the scientific principles of operation and the product's mode of action, plus the core rationale for qualifying it as a medical device alongside the risk class and the explicit justification for the classification rules applied in accordance with Annex VIII. If your device has novel characteristics, works with accessories or relies on specific market configurations and variants, these must all be documented in detail.
Material Chemistry and Technical Documentation Requirements
Regulators require what your device is made of and how it works. These technical documentation requirements mean documenting the formulation, composition and functional elements of all parts, including embedded software. You must back this up with labelled diagrams, photographs or drawings so the internal mechanics are easy to understand.
Pay close attention to your bill of materials because you must document all raw materials used in key functional elements, focusing heavily on anything making direct or indirect contact with the human body. Alongside these internal specifications, your file must include the commercial details that usually appear in user-facing brochures or catalogues. These details may also support medical device import requirements when the product is prepared for target markets. If applicable, you also need to provide an overview of previous generations of your device or similar products already available on international markets, plus copies of all device labels and instructions for use translated into the accepted languages of your target countries.
Design Evolution Under the European Medical Device Regulation
Your technical file medical device record must explain the applied design stages and provide validation data for your manufacturing processes. This includes complete data on manufacturing adjuvants, continuous monitoring and final product testing. Under the European medical device regulation, you must identify every site involved in development, including the physical locations of your third-party suppliers and sub-contractors.
A major milestone in your dossier is demonstrating conformity with the General Safety and Performance Requirements (GSPR) set out in Annex I. You must document exactly which GSPRs apply to your device, explain why others were omitted and detail the methods or harmonised standards used to prove compliance. The technical documentation requirements also cover direct links to controlled documents, with a precise cross-reference map showing where the evidence is located. This section must also contain your full risk management results and benefit-risk analysis.
Technical File Medical Device Safety Validation and Specialized Clinical Testing
Proving your device works safely requires testing data, so your MDR technical documentation must include a critical analysis of all engineering, laboratory, simulated-use and animal tests. You must provide detailed study designs, protocols and data summaries covering biocompatibility, physical and chemical characterisation, electrical safety, electromagnetic compatibility and shelf-life stability. If your device relies on software, you must show validation evidence within the finished device across all intended operating systems and hardware setups before release. Where applicable, you must also prove conformity with Good Laboratory Practice.
Your core clinical files must feature the formal clinical evaluation report, the clinical evaluation plan and your Post-Market Clinical Follow-up (PMCF) plan. Certain devices require specialized technical pathways:
Devices incorporating an integral medicinal substance or human blood derivatives must include safety and usefulness test data.
Products using tissues, cells or derivatives must state this and detail compliance with the applicable safety annexes.
If a device is introduced into or absorbed by the human body, you must provide extensive data on its metabolism, excretion, local tolerance and systemic toxicity.
Sterile products must include environmental descriptions for manufacturing steps, together with validation reports for packaging, sterilization, bioburden and pyrogen testing.
Devices with a measuring function must outline how they maintain accuracy, while connected systems must prove they meet performance requirements when linked to other hardware.
MDR Technical Documentation and Post-Market Surveillance
Compliance does not end at commercial launch because the European medical device regulation requires you to maintain an active Post-Market Surveillance (PMS) system drawn up in accordance with Articles 83 to 86. Your PMS plan must systematically gather data from serious incidents, field safety corrective actions, trend reports, technical literature and direct user complaints.
The plan must define the precise methods you will use to assess this data, including specific indicators and threshold values to continuously reassess your product's benefit-risk profile. It must outline your tools for investigating field issues, statistical protocols for catching unexpected trends and communication channels for alerting notified bodies and authorities. Finally, the MDR technical documentation must contain clear procedures for executing corrective actions, tools to trace affected devices in the field and your finalized Post-Market Surveillance Reports or Periodic Safety Update Reports (PSUR).
Medical Device Import Requirements for Labels and Languages
When devices are supplied in several markets, the medical device import requirements may affect the labels and instructions for use included in the file. You must provide labels for the device and all packaging, including single-unit, sales and transport packaging. The labels and instructions for use must be available in the specific languages accepted by the target member states. These medical device import requirements should be checked for each target country before the documentation is finalized.

Frequently Asked Questions
What are the registration costs or timelines for overseas manufacturers?
The document does not provide details on costs, timelines or market-entry barriers; it only sets out the technical documentation requirements for the file.
Are there any physical site visits or audits to my facility?
It does not state whether physical inspections or audits will take place, but you have to identify all locations where design and manufacturing are carried out, including your suppliers and sub-contractors.
What clinical data or evaluation plans do we need for verification?
You must provide the full clinical evaluation report with updates and the clinical evaluation plan. You also need a Post-Market Clinical Follow-up (PMCF) plan and report, or a clear reason why PMCF does not apply to your device.
If we use sub-contractors, how does that change our submission?
You must explicitly name all sites where design and manufacturing take place. Your files cannot cover only your main facility; they must include the roles and identities of your suppliers and sub-contractors.
What are the labeling and language rules for importing devices?
You must provide labels for the device and all packaging, including single-unit, sales and transport packaging. The labels and instructions for use must be in the specific languages accepted by the target member states where you want to sell the device. By using Morulaa's medical device regulatory consulting services, manufacturers can review the file, identify gaps and prepare the required documentation before submission.
