This document provides guidance on technical documentation and design dossiers for non-active medical devices. It discusses the differences between technical documentation used for class I, IIa, and IIb devices, and design dossiers used for class III devices. Technical documentation is retained by the manufacturer or authorized representative, while design dossiers must be submitted to a notified body for review prior to CE marking. The document outlines the structure and required contents for technical documentation and design dossiers, including essential requirements checklists, risk analysis documentation, drawings and specifications, preclinical test reports, and more. Proper documentation helps ensure compliance and allows for efficient review.
