Patent ID: 7407503

Claim:
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 connectable 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 connectable to the first terminal, wherein the third lead is electrically connected to the third medical-treatment electrode and is electrically connectable to a second terminal of the medical radio-frequency (RF) generator, and wherein the contact area of the first, second, and third medical-treatment electrodes each has a substantially rectangular shape including a length and a width.
