Microcurrent Device (TIVIC Health)

The study device is a handheld micro-current TENS emitter intended to be used for the relief of postoperative pain after FESS. The design of the study device was optimized to provide transcutaneous nerve stimulation to the regional areas associated with the sinuses.

The sham device appears and operates identically to the active device, including indicator lights and haptic vibration, however it emits a weak direct current that is non-therapeutic.
