A system for applying a plasma discharge and/or electric field, comprising: a controller (4); an electrode (3) adapted to be placed proximate an anatomical region of interest, the electrode (3) having an array of conductors; and a power supply in electrical communication with the electrode (3) and controller (4), the power supply being adapted and configured to apply power to the electrode (3), characterized in that the array of conductors are adapted and configured to be selectively activated and deactivated by the controller (4), the power supply being adapted and configured to apply power to the electrode (3) to generate a moving plasma over time in the anatomical region of interest by activating a plurality of conductors in the array of conductors.
