How to structure your technical file for your Medical Device

A technical file is not something that is only required for medical devices. When we look at the Blue guide for implementation of EU products rules, it's clear that all products that fall under a European legislation require a Technical File before being allowed to be put on the market.

As the technical documentation or technical file is used to evaluate whether the device is compliant to the regulatory requirements, it's critical to have a well-structured file. This will enable the reviewers to find the information they are looking for in an easier and faster way, which will lead to less nonconformities and a faster time to market.

1. Understanding the Technical File

For medical devices, a technical file is a comprehensive collection of documents that provide detailed information about the device. It serves as a record of the design, development, and performance of the device, ensuring that it meets regulatory standards and is safe and effective for use. The primary purpose of a technical file is to demonstrate compliance with relevant regulatory requirements, providing evidence that the device is designed and manufactured according to industry standards and regulations.

The key components of a technical file are:

  1. Device Description and Specifications: Detailed information about the medical device, including its intended use, design, components, and physical characteristics.

  2. Risk Management Plan: A comprehensive assessment of potential risks associated with the device, along with mitigation strategies to ensure safety.

  3. Clinical Evaluation Reports: Evidence from clinical trials or studies demonstrating the device's safety and efficacy.

  4. Quality Management System Documentation: Records of the processes and procedures used to maintain quality throughout the device's lifecycle.

  5. Design and Manufacturing Information: Detailed documentation of the design process, materials used, manufacturing methods, and quality control measures.

  6. Labeling and Instructions for Use: Information provided to end-users, including labels, packaging, and instructional materials.

  7. Post-Market Surveillance Plan: A strategy for monitoring the device's performance and safety once it is on the market.

2. Regulatory Requirements

Overview of FDA and EU MDR Requirements

FDA Requirements

The U.S. Food and Drug Administration (FDA) oversees the regulation of medical devices in the United States. The FDA's requirements for a technical file, often referred to as a Device Master Record (DMR) and Design History File (DHF), include:

  • Premarket Notification (510(k)) or Premarket Approval (PMA)): Evidence that the device is safe and effective, either through substantial equivalence to a legally marketed device or through extensive clinical data.

  • Quality System Regulation (QSR): Documentation of the quality management system in compliance with 21 CFR Part 820 and ISO 13485.
