FDA Clearance

The Fisher Wallace Stimulator®, previously branded the Liss Cranial Stimulator®, was cleared by the FDA in 1990 for the treatment of depression, anxiety, insomnia and chronic pain - the longest tenure of regulation of any wearable neurostimulation device on the market.

The safety and effectiveness of the Fisher Wallace Stimulator® has been proven in multiple published studies, including a clinical trial conducted at Mount Sinai Hospital and published in the Journal of Nervous and Mental Disease in 2015. The device is also used by top substance abuse clinics such as Phoenix House where it increased patient retention by 50% in a 392-subject study conducted in 2012.
