Electrosurgical methods and devices employing inductive energy

A device for applying RF energy to biological tissue comprising:

• one or more primary electrodes disposed on a treatment probe;
• means for supplying RF energy to the one or more primary electrodes;
• and
• means for creating a supplemental magnetic field,
• wherein the primary electrodes and the RF energy supply are configured to create an electrical current in the tissue at a first depth below a tissue surface and an electrical current in the tissue at a second depth below the surface, wherein the first depth is closer to the surface than the second depth,
• wherein the means for creating the supplemental magnetic field are configured to modify the RF energy supply through the primary electrodes to make the current at the second depth larger than the current in the first depth, and
• wherein the current at the first depth remains below the level sufficient to cause ablation.
