Gaining ANVISA approval

Before medical device manufacturers can legally sell their products in Brazil, they must comply with Brazilian medical device regulations set forth by the National Health Surveillance Agency (ANVISA).

The approval process in Brazil can take time, so it is best to confirm the correct classification and grouping of your medical device before starting the ANVISA registration process. Improper classification or grouping into product families, slight changes to formulations, or claims of performance that cannot be substantiated by clinical data can significantly impact the regulatory approval process and its associated costs.

Determining your ANVISA device classification and grouping

In the ANVISA regulatory process, the first step in determining your path to compliance with Brazilian regulations is to ascertain the classification of your medical device. Devices are classified into four classes based on risk (Class I-IV).

ANVISA’s classification system is based on the classification rules in Annex IX of the European Medical Devices Directive. As such, classifications are often consistent between Europe and Brazil. For example, a Class IIa/IIb device in Europe is usually a Class II/III device in Brazil. If you have multiple products, you must determine the correct product family grouping, which will determine the number of submissions required to ANVISA.

Device registration routes in Brazil

Once devices are classified and grouped, manufacturers must follow the Notificação or Registro registration route, depending on their classification. Class I and II devices are considered low-risk and therefore eligible for the Notificação application process, which does not require ANVISA review. Class III and IV devices are deemed higher-risk by ANVISA and must go through the Registro registration process.

Common questions regarding ANVISA

What is considered a device family - what products can be in a single submission?

Brazil considers similar criteria for a product family as in other major global markets, i.e., same intended use, same indications for use, same technology, manufacturer, and so on. Differences in size, dimension, or shape, for example, generally do not matter (although certain products, such as orthopedic implants, will consider differences like these).

How long is our ANVISA registration valid?

The term of your ANVISA registration varies by class. Class III and IV registrations are valid for ten years; whereas Class I and II registrations no longer have an expiration date.
