Medical Device File Template
Medical Device File
Every medical device needs a single, organized file that ties together its description, specifications, manufacturing processes, and supporting procedures. This is the Medical Device File (MDF), a core quality system requirement under ISO 13485:2016. This guide provides a medical device file template, explains how it compares to an MDR technical file template, and walks through a practical checklist for building one.
What Is a Medical Device File?
A Medical Device File is a structured set of documents, or references to documents, maintained for each medical device type or family. ISO 13485:2016 (clause 4.2.3) requires manufacturers to establish and maintain one for every device they produce, covering its general description, intended use, specifications, manufacturing and related processes, and the procedures needed to measure and monitor the device.
The purpose and scope of the file should be clearly defined at the outset:
- Purpose: what the file is for, within the manufacturer's quality management system
- Scope: which device, model, or device family the file covers
Rather than duplicating every underlying record, a Medical Device File typically works as a central index, pointing to the specific procedures, specifications, and records held elsewhere in the quality system. That makes it a map of the device's full lifecycle rather than a standalone technical dossier.
Medical Device File Requirements
A compliant Medical Device File should give a complete, traceable picture of the device. At minimum, it should:
- Identify the device by name and model number
- State the intended use of the device clearly
- Describe the device and its mode of operation
- Record the device's classification under the applicable regulatory framework
- Reference all labelling information, including the instructions for use (IFU)
- Capture the device's technical specifications
- Reference the procedures governing manufacturing, packaging, storage, handling, and distribution
- Reference measuring and monitoring procedures, including calibration and data analysis
- Reference servicing procedures, where the device requires servicing
- Reference installation requirements, where applicable
- List the regulatory standards and guidance documents the device is designed and manufactured against
Each item should point to a specific procedure, specification document, or record, not a general statement, so the file functions as a genuine index into the quality system rather than a collection of vague assurances.
Medical Device File Contents
Device Description and Specifications
This section anchors the whole file. It should include:
- Device name and model number: the specific identifier used on the device and its labelling
- Device description: a description of the device and its mode of operation
- Product specifications: the technical specification of the device, covering performance characteristics, materials, dimensions, and other defining parameters
Intended Use and Indications
The intended use statement defines the medical purpose of the device: what condition it addresses, for which patients, and under what circumstances. Everything else in the file, from risk management to clinical evaluation, should remain consistent with what is stated here. Any indications for use, contraindications, and limitations should also be captured in this section or clearly referenced from it.
Design and Manufacturing Information
This section references the processes that turn the device design into a finished, distributable product:
- Manufacturing process: the documented process by which the device is produced
- Packaging process: how the device is packaged to maintain its safety and performance
- Storage process: the conditions and procedures for storing the device prior to distribution
- Handling and distribution process: how the device is handled and distributed to maintain its integrity
- Installation requirements: where the device requires installation, the requirements and procedure references for doing so correctly
Risk Management
Although often maintained as a separate risk management file under ISO 14971:2019, the Medical Device File should reference the risk management documentation relevant to the device, including the risk management plan, risk analysis, and risk control measures. This keeps the device's safety profile visible from within the central file, even where the detailed risk records are held elsewhere.
Labelling and Instructions for Use
This section should reference:
- All labelling information applied to the device
- The instructions for use (IFU), including where the current approved version is held
- Any other accompanying documentation provided with the device
Keeping labelling and IFU references current in the Medical Device File helps ensure the file reflects exactly what ships with the device, not an earlier design iteration.
Verification and Validation
This section references the procedures that confirm the device, and the processes that produce it, perform as intended:
- Measuring and monitoring procedures: describing the processes used, with references to the underlying procedure documents
- Calibration process: how measurement and monitoring equipment is calibrated to maintain accuracy
- Analysis of data: how data gathered from measuring and monitoring activities is analyzed and acted upon
- Servicing procedures: the documented processes for servicing the device, with procedure references, where servicing is part of its lifecycle
Clinical Evaluation
For devices where clinical evidence is required to demonstrate safety and performance, the Medical Device File should reference the clinical evaluation documentation, including the clinical evaluation report or equivalent evidence appropriate to the device's risk classification. This keeps the clinical evidence trail connected to the rest of the device's technical record.
Post-Market Surveillance
The file should also reference the manufacturer's post-market surveillance activities for the device: complaint handling trends, adverse event summaries, and any corrective or preventive actions arising from post-market data. This closes the loop, showing that the device continues to be monitored after it reaches the market, not just during development.
MDR Technical File Template
A Medical Device File under ISO 13485 and a technical file under the EU Medical Device Regulation (MDR) 2017/745 cover overlapping ground, but they are not identical documents, and it is worth being clear about the difference.
- ISO 13485 Medical Device File: a quality-system requirement, structured mainly around manufacturing, process control, and traceability. It can act as an index pointing to other controlled documents in the quality system.
- EU MDR technical documentation (the "technical file"): a formal regulatory dossier required under Annex II and Annex III of the MDR, assessed directly by a notified body (for most classes) as part of conformity assessment. It is considerably more prescriptive about content and structure than the ISO 13485 requirement.
An MDR technical file template generally needs to address, at minimum:
| MDR Annex II/III area |
What it covers |
| Device description and specification |
Including variants, accessories, and intended purpose |
| Information supplied by the manufacturer |
Labelling and instructions for use |
| Design and manufacturing information |
Sufficient detail to understand the design and manufacturing stages |
| General safety and performance requirements |
A checklist mapping each requirement to the evidence demonstrating conformity |
| Benefit-risk analysis and risk management |
Per ISO 14971, integrated throughout the file |
| Product verification and validation |
Including biocompatibility, software verification, and sterilization, as applicable |
| Clinical evaluation |
A clinical evaluation report consistent with MEDDEV/MDCG guidance |
| Post-market surveillance plan |
Including the post-market surveillance report or periodic safety update report, depending on class |
In practice, many manufacturers build their EU technical file and their ISO 13485 Medical Device File from the same underlying source documents, mapping each one to both structures rather than duplicating the content twice. A well-organized Medical Device File, used as an index, can make assembling the MDR technical file considerably faster, since most of the supporting evidence it points to is the same evidence a notified body will expect to see.
How to Prepare a Medical Device File
- Define the purpose and scope. State clearly what the file covers: a single device, a specific model, or a device family.
- Identify the device. Record its name, model number, and intended use.
- Describe the device. Capture its mode of operation and a clear description suitable for someone unfamiliar with it.
- Classify the device. Record its classification under the applicable regulatory framework for your target market.
- Compile product specifications. Reference the technical specification document rather than rewriting it inside the file.
- Reference manufacturing-related procedures. Link to the manufacturing, packaging, storage, and handling and distribution process documents.
- Reference measuring and monitoring procedures. Include calibration process references and how data analysis is performed.
- Reference servicing and installation procedures. Include these where the device requires servicing or installation.
- Reference labelling and IFU documentation. Confirm the current, approved versions are what the file points to.
- List applicable regulatory standards. At minimum, reference ISO 13485:2016 for quality management systems and ISO 14971:2019 for risk management, plus any device-specific standards.
- Cross-check against risk, clinical, and post-market references. Confirm the file also points to the relevant risk management, clinical evaluation, and post-market surveillance documentation.
- Review and approve. Have the file reviewed against the quality management system's document control procedure before it is finalized.
- Keep it current. Update the file whenever the device design, manufacturing process, labelling, or applicable standards change.
