What is an AIMD?

As one of the highest risk categories of device, Active Implantable Medical Devices (AIMDs) are subject to rigorous regulatory controls before they can reach global markets. The Medical Device Regulation (MDR) (EU) 2017/745 defines the requirements of these medical devices.

An Active Implantable Medical Device is defined as:

  • A device the operation of which depends on an energy source other than that generated by the human body for that purpose or by gravity, and which acts by changing the density of or converting that energy,
  • Which is to be totally introduced into the human body or used to replace an epithelial surface or the surface of the eye by clinical intervention,
  • Which is intended to remain in place after the procedure,
  • And includes any active device intended to be partially introduced into the human body by clinical intervention and intended to remain in place after the procedure for at least 30 days.

All Active Implantable Medical Devices and their accessories are classified as Class III and therefore subject to the most rigorous regulatory controls. For further clarity and more detailed information on an AIMD, please reference the MDR (EU) 2017/745.

AIMDs are subject to rigorous regulatory controls both pre- and post-market. The regulatory controls set out in the MDR also apply to any accessories that are used to enable the device to operate as intended, for example: battery packs, controllers, implant kits, leads, programmers, refill kits, and software applications.
