Abstract
Apparatus and methods for evenly distributing electric current density over a surface of at least one of an active electrode and a return electrode during electrosurgery, wherein the active and/or return electrode includes a spiral inductor. The spiral inductor may include a low electrical resistivity material or a spiral bare metal surface for contacting the patient's body. In a multi-layer spiral inductor having a plurality of stacked spirals, each turn of a first spiral may be electrically coupled in series to a radially corresponding turn of each successive one of the stacked spirals; and each turn of the innermost spiral may be electrically coupled to an adjacent, radially outward turn of the outermost spiral.
