I’ve seen the term has been left untranslated in several English-language websites. It may appear as “cadastro registration pathway”, “cadastro route”, “cadastro license”, etc.:

Please note:
“ ANVISA: New Registration Regime for Class II Medical Devices
Brazil’s National Agency of Health Surveillance (ANVISA) published a new Resolution of the Collegiate Board of Directors (RDC No. 423/2020). The new resolution declared the elimination of the Cadastro registration pathway for Class II medical devices and IVDs and substituted the same with a notification registration pathway (Notificação). The main goal of this new resolution is to further concentrate on high-risk medical devices and IVDs.” https://www.freyrsolutions.com/blog/anvisa-new-registration-...

I suggest double-checking to find out if the above information is still current.
