The same medical device, different sizes and models, in the development process, to verify separately?

Yes. Although it is the same kind of medical device, but the size and model are different, which indicates that there are differences in the function of the two machines, so it is necessary to verify separately. Medical devices are instruments, equipment, apparatus, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly in the human body, including the required computer software.
