Medical Device Dossiers: Structure, Content, and Evidence

The preparation and submission of a comprehensive technical file, also known as a dossier, is a critical step towards gaining regulatory approval and market access. This dossier serves as a compilation of essential documentation that provides regulatory bodies with a detailed understanding of the device's design, manufacturing processes, safety measures, and performance characteristics.

Different regulation The Medical Device Dossier is known by different names like in India it is Known as Device Master File, in EU union it is called as  Technical Construction File, and globally it is known Medical Device Dossier or Technical File. 

In this article, we explain the fundamental structure of the medical device dossier as outlined by regulatory bodies such as the European Union (EU), the Central Drugs Standard Control Organization (CDSCO) in India, and the U.S. Food and Drug Administration (FDA). This standardized structure serves as a blueprint for manufacturers, guiding them through the intricate process of compiling and organizing the necessary evidence to support regulatory submissions.

Our exploration begins with an overview of the basic sections comprising the dossier, including an executive summary, device description, manufacturing details, safety assessments, and clinical evidence. We dissect each section, highlighting its purpose and the key documentation expected to be included. Additionally, we discuss the importance of adherence to relevant quality standards and regulatory requirements throughout the dossier compilation process.

The basic document structure as per IMDRF

Section	Description of Evidence
Section 1: Executive Summary & Device Description	Regional regulatory overview, Device description inclduing but not limited to product specification
Section 2: Information Supplied by Manufacturer with Device	Documentation provided with the device for users which includes but not limited to User Manual, brohures, catalogues, promotional material, warranty card
Section 3: Designs & Manufacturing	Details on device design and manufacturing processes which includes whole design and development file, transfer checklist, manufacturing specification, process and master lot quality data, critical component lists and specifications
Section 4: Safety Checklist	Safety and Performance Requirements checklist as per the applied regulatory body
Section 5: Risk Management File	Assessment of device risks and risk management strategies which includes a Complete Risk Management File and methodologies to collect and identify subsequent risks throughout the device life cycle.
Section 6: Verification and Validation	Testing and validation activities to ensure device performance which includes real time evidence
PMS & PMPF/PMCF	Post-Market Surveillance and Post-Market Clinical Follow-up
Clinical Evaluation	Evaluation of clinical data supporting device safety and performance, Clinical  Evaluation report
Quality Plan & Assurance	Quality management system documentation and assurance measures, Stability Study Data, Biocompatibility Data, Clinical Evidence,
Common Specifications as  per Applicable Standards	Specifications conforming to applicable standards

The whole Technical Dossier is divided in to Six section aiming to put together pertinent data with evidences. By systematically addressing key aspects such as device description, manufacturing processes, risk management, verification, validation, and post-market surveillance, the dossier aims to demonstrate compliance with regulatory requirements and ensure the device's safety, quality, and efficacy. Through this structured approach, manufacturers can effectively navigate the regulatory landscape, facilitate the review process, and ultimately obtain the necessary approvals for market authorization.

Requirements for Suppliers of Medical Devices and Materials used to Manufacture Medical Devices

The central objective of the Rules & Regulation are to ensure the highest possible level of patient safety thanks to high-quality medical products, which requires the supervision of supply chains between manufacturers* and suppliers**.

The Rules & Regulation imposes clear responsibilities on manufacturers*, in particular with regard to liability for products placed on the market. Therefore, the procured (preliminary) products which are processed or incorporated into the product as raw material, intermediate products, accessories or commodities must comply with the requirements to the extent that the manufacturer can declare that the finished medical device complies with the general safety and performance requirements.

* The Manufacturer is the company indicated on the ready-for-sale medical device or as applicable Definition in the regulatory jurisdiction.
** The Supplier provides the manufacturer with medical devices or materials required for the production of such devices. The supplier’s obligations and responsibilities are set out in this confirmation, supply and purchasing agreements, contracts and statutory provisions.

Suppliers of medical devices and materials play a crucial role in ensuring the quality, safety, and efficacy of medical devices. Therefore, it's essential for manufacturers to establish stringent requirements for their suppliers to maintain high standards throughout the supply chain. Here are some key requirements for suppliers:

1. Compliance with Regulatory Standards: Suppliers must adhere to all relevant regulatory standards and requirements applicable to their products. This includes obtaining necessary certifications and approvals from regulatory authorities.
2. Quality Management System: Suppliers should have robust quality management systems in place to ensure consistency and reliability in their products. This includes implementing quality control measures, conducting regular audits, and maintaining documentation of processes and procedures.
3. Product Specifications: Manufacturers must provide clear specifications to their suppliers regarding the materials and components required for the manufacture of medical devices. Suppliers should ensure that their products meet these specifications and are suitable for use in medical devices.
4. Traceability and Documentation: Suppliers should maintain detailed records of their products, including traceability information such as batch numbers, lot codes, and expiration dates. This documentation is essential for tracking and identifying any issues that may arise during manufacturing or post-market surveillance.
5. Risk Management: Suppliers should conduct risk assessments for their products and processes to identify and mitigate any potential risks to patient safety or product efficacy. This includes assessing risks related to materials composition, manufacturing processes, and supply chain disruptions.
