Technical File or Design Dossier Management – EU MDR

A CE Technical File or Design Dossier is a complete description for a medical device intending to show compliance with EU MDR’s requirements. For a medical device manufacturer, preparing a technical file or design dossier is an essential step in Europe’s CE marketing process.
