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

What is considered an accessory for a medical device?

Any item that, while not itself a medical device, is intended by its manufacturer to be used with one or more given medical devices to:

  • enable the device(s) to be used in accordance with its/their intended purpose; or
  • specifically and directly contribute to the medical function of the medical device(s) as intended.

Software that drives or influences the use of a medical device (hardware) may be described as an accessory for a medical device (hardware).

As a reminder:

Software is said to influence or control a medical device when it does not by itself have a medical purpose but controls or influences the use of a medical device (hardware). This software can, but is not limited to:

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


Consult the European regulations

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.
