Abstract
Tumor treating fields (TTFields) may be applied to a person's body using six different types of electrodes. More specifically, the electrodes may be shaped and dimensioned (a) for insertion into blood vessels so that they make contact with the person's blood; (b) for insertion into a central canal of a spinal cord, so that they make contact with the CSF; (c) for insertion into a body orifice at a position that contacts an interior surface of the person's body; (d) for affixation to skin of the person's body (e.g., on the person's head, torso, back, abdomen, etc.); (e) for insertion into a brain ventricle so that they make contact with the person's CSF; or (f) for insertion into lymph vessels so that they make contact with the person's lymph. Applying an AC voltage between any two of these electrodes will create TTFields in respective parts of the person's body.
