Abstract:
An electrode array supports multiple electrodes and energizes them so that adjacent electrodes do not have the same polarity. In one embodiment, the electrodes are held about a circumference outside and surrounding a tumor and opposed electrodes are energized in a round robin fashion to promote current flow through the center of the tumor from a variety of angles.
