Diagnostics: Purpose of my service

Please note that the results correspond to the answers you have ticked. They provide an insight but cannot replace the personalised and in-depth analysis that a legal or regulatory expert can provide.

Is your product an accessory to a medical device, does it influence or control the operation of a medical device?

What is an accessory to a medical device?

Any device which, without being a medical device itself, is intended by its manufacturer to be used with one or more medical devices to:

  • Enable the medical device(s) to be used in accordance with its intended purpose ;
  • Or contribute directly and explicitly to the indended medical function of the medical device(s).

Additionally, it is worth noting that a software program designed to control or impact the use of a hardware medical device may also be classified as an accessory to a medical device.

As a reminder:

A software is said to control or affect a medical device when it has no medical purpose of its own. Such software may, but not limited to:

  • Operate, change the state of, or control the device through an interface (e.g., software, hardware) or through a human operator ;
  • Provide results related to the operation of the hardware of that device.

To determine if the product you are developing is an accessory to a medical device, it must meet the definition of an accessory and be intended for use with a product that itself qualifies as a medical device.

If your product has multiple components, you may choose to address each component separately from a regulatory perspective, in which case answer the question for each component. You may also choose to treat the individual components as a whole from a regulatory perspective, in which case answer "no" and proceed to the next question to determine if your product is a medical device.

  • Example: a mobile application wirelessly connected to a blood pressure monitor to display and record the patient's blood pressure.

Please note that G_NIUS is not designed to help you choose the regulatory strategy to adopt, for that you can call on regulatory specialists.
