  1. 1. Med-Info Regular Information Bulletins for the Medical Device Industry Product ServiceDesign DossiersDesign dossiers are technical files for class III It is recommended to compile a Designdevices and comprehensively examined by the Dossier or Technical File as followsNotified Body. (see also NB-MED/2.5.1 and GHTF document SG1 (PD)/N011R20: STED):Medical Device Directive (MDD) Annex IISection 4.2 states that an application for PART A: Technical Fileexamination of the design of the product mustinclude the documents needed to assess 1.
