Tumors inside a person's head (e.g., brain tumors) can be treated using tumor treating fields (TTFields) by positioning capacitively coupled electrodes on opposite sides of the tumor, and applying an AC voltage between the electrodes. Unlike the conventional approach (in which all of the electrodes are positioned on the person's scalp) at least one of the electrodes is implemented using an implanted apparatus. The implanted apparatus includes a rigid substrate shaped and dimensioned to replace a section of the person's skull. At least one electrically conductive plate is affixed to the inner side of the rigid substrate, and a dielectric layer is disposed on the inner side of the conductive plate or plates. An electrically conductive lead is used to apply an AC voltage to the conductive plate or plates.

An electrode system includes an electrode, a connector, and a cable with an in-line radio-frequency filter module comprising resistors and inductors without any deliberately added capacitance. The resistors are arranged in an alternating series of resistors and inductors, preferably with resistors at both outer ends, and connected electrically in series. The in-line module is located at a specific location along the wire, chosen through computer modeling and real-world testing for minimum transfer of received RF energy to a patient's skin, such as between 100 cm and 150 cm from the electrode end of a 240 centimeter cable. The total resistance of the resistors plus cable, connectors and solder is 1000 ohms or less; while the total inductance is roughly 1560 nanohenries. The inductors do not include ferrite or other magnetic material and are, together with the resistors, stock components thereby simplifying manufacture and reducing cost.
