I have to defiantly agree with neb2, the DHF is a lot more useful than the design dossier since this file have detailed information bout the design, function, composition, use, claims and clinical evaluation of the medical device and it seem important but there a lot other information that is missing and I believe that the DHF have a lot of more crucial information that can be really useful for the medical device. We be able to learn a lot more using the DHF than using the design dossier.
