A transformer-coupled plasma source using toroidal cores forms a plasma with a high-density of ions along the center axis of the torus. The system includes a cryoballoon catheter with a cryoballoon, a distal electrode, a proximal electrode, and a temperature sensor. The IRD data used to build the print file may be from an external application. The transcoded multimedia information may then be transmitted to the receiver over the downlink channel using a transmission timer.
