The externally worn transmitter (wearable antenna assembly (WAA)) is an electronic device used to power the receiver that is placed under the skin. The Freedom System uses wireless technology for power. Wireless power is sent from the WAA and through the skin to the Receiver, that is coupled with the implanted Stimulator. The implanted Receiver and Stimulator only accept power and parameter settings from a personalized, specific WAA for each patient.
