Medical-treatment electrode assembly having treatment-monitoring application

A medical-treatment electrode assembly comprising:

• a) spaced-apart first, second, and third medical-treatment electrodes each having a contact area contactable with patient tissue, wherein the second medical-treatment electrode is disposed between the first and third medical-treatment electrodes and is disposed closer to the first medical-treatment electrode than to the third medical-treatment electrode, and wherein the contact area of the second medical-treatment electrode is smaller than the contact area of the first medical-treatment electrode;
• and
• b) first, second, and third leads, wherein the first lead is electrically connected to the first medical-treatment electrode and is electrically connected to a first terminal of a medical radio-frequency (RF) generator, wherein the second lead is electrically connected to the second medical-treatment electrode and is electrically connected to the first terminal, and wherein the third lead is electrically connected to the third medical-treatment electrode and is electrically connected to a second terminal of the medical radio-frequency (RF) generator,
• wherein the contact area of the first, second, and third medical-treatment electrodes each has a substantially rectangular shape with a length and a width, and wherein the first, second and third medical treatment electrodes are substantially parallel and width-wise aligned.
