Abstract
Embodiments herein relate to a medical device for treating a cancerous tumor, including an electric field generating circuit configured to generate one or more electric fields at or near a site of the cancerous tumor and control circuitry in communication with the electric field generating circuit. The medical device includes one or more supply wires in electrical communication with the electric field generating circuit and one or more supply electrodes. The supply electrodes are configured to deliver an electric field at or near the site of the cancerous tumor. The medical device can include one or more sensing wires in electrical communication with the control circuitry and one or more sensing electrodes. The sensing electrodes can be configured to measure an impedance of the cancerous tumor at at least two different electric field strengths. Other embodiments are also included herein.
