The company behind the NEMOS® therapy device is the innovative medical technology company tVNS Technologies GmbH based in Erlangen, Germany. We specialize in the field of neurostimulation, with a focus on transcutaneous vagus nerve stimulation (t-VNS), to offer an alternative therapy option for patients with neurological diseases.
