In common with pacemakers, implantation of<unk>  devices carries risks of bleeding, bruising and infection. The location of the electrode, on the carotid artery, carries a theoretical risk of disturbing plaque inside the carotid artery that in principle could cause a stroke, although protocols typically include scanning the artery for plaques beforehand, and such events appear not to have occurred in the systematic trials. High stimulation voltages can cause an appreciable sensation which can be unpleasant. In typical use the device output voltage is adjusted to below the level that causes unpleasant sensations.
