Non-invasive neuromodulation products are medical devices that use electrical stimulation to modulate the activity of the nervous system without the need for surgery. These products are used to treat a variety of neurological conditions, including chronic pain, depression, epilepsy, and Parkinson’s disease. Examples of non-invasive neuromodulation products include transcutaneous electrical nerve stimulation (TENS) units, transcranial magnetic stimulation (TMS) devices, and vagus nerve stimulation (VNS) systems.
