No, we do not have any special clearance by the TSA to carry our medical device onboard.
However, the REVIAN RED system is a limited energy device similiar to mobile phones that have lithium polymer batteries and can be carried on airplanes. The screeners are unlikely to ask about it but since it is a FDA-Cleared medical device it is perfectly safe to carry onboard. Restrictions to using the device are subject to onboard mobile device usage. See your airline for more details.
