The present disclosure provides a plasma system including an electrosurgical generator an ionizable media source and a plasma instrument. The plasma instrument includes a housing having a lumen defined therein terminating in an opening at a distal end thereof, the lumen being in fluid communication with an ionizable media source and a pair of electrodes coupled to the electrosurgical generator. The plasma system also includes a return electrode pad configured to couple to a patient and a polarization controller electrically coupled to the return electrode, the polarization controller configured to adjust conductive coupling of the return electrode pad to the electrosurgical generator.
