NERVANA Founders

Two brothers, both physicians, had an idea to take the best part of a surgically implanted nerve stimulation product and to provide it to users in a way that was entirely non-invasive. Drs. Richard and Daniel Cartledge formed NERVANA LLC, including a team of multi-disciplinary medical and intellectual property experts and engineers to make that dream a reality. The team created NERVANA – a breakthrough wearable consumer product that accesses the Vagus nerve without surgery or percutaneous action and does so in harmony with recorded and live music.
