Yes, you can travel with the Revian systems. There is no special clearance required by the TSA to carry the Revian device onboard a commercial aircraft. The Revian system is a limited energy device similar to mobile phones that have lithium ion batteries and can be carried on airplanes. The screeners are unlikely to ask about it, but as it is an FDA-Cleared medical device it is perfectly safe to carry onboard. Restrictions to using the device are subject to onboard mobile device usage. Please contact your airline directly for more details.
