The Altius® Direct Electrical Nerve Stimulation System is the first device FDA-approved to specifically address chronic post-amputation pain. Altius is indicated as an aid in the management of chronic intractable phantom and residual lower limb post-amputation pain in adult amputees. It is a patient-controlled, on-demand system that uses Neuros’ patented technology to address the underlying cause of post-amputation pain by inhibiting pain signal transmission from damaged peripheral nerves to the central nervous system.
