Claim 0:
1. A method for forming an ablation, including the steps of:
providing a first bipolar electrode set having first and second electrode groups, the first electrode group including one or more electrodes and the second electrode group having at least one more electrode than the first electrode group and forms a low impedance return path for RF current;
wherein each of the one or more electrodes of the first electrode group of the first bipolar electrode set is connected to an excitation voltage;
wherein the electrodes of the second electrode group of the first bipolar electrode set collectively form the low impedance return path for RF current;
disposing the first bipolar electrode set within a body;
providing a second bipolar electrode set having first and second electrode groups, the first electrode group including one or more electrodes and the second electrode group having at least one more electrode than the first electrode group and forms a low impedance return path for RF current;
wherein each of the one or more electrodes of the first electrode group of the second bipolar electrode set is connected to an excitation voltage;
wherein the electrodes of the second electrode group of the second bipolar electrode set collectively form the low impedance return path for RF current;
disposing the second bipolar electrode set within the body;
applying an energy for a period of time to the first bipolar electrode set to form a first portion of the ablation at the first bipolar electrode set;
sequentially applying an energy for a period of time to the second bipolar electrode set to form a second portion of the ablation at the second bipolar electrode set;
repeating the steps of applying the energy to the first bipolar electrode set and then applying the energy to the second bipolar electrode set so as to incrementally form the ablation;
wherein the number of times of repeating the steps of applying the energy to the first bipolar electrode set and second bipolar electrode set is at least 100 times;
wherein the period of time for applying the energy to the first bipolar electrode set is in the range of 10 milliseconds to 1500 milliseconds and wherein the period of time for applying the energy to the second bipolar electrode set is in the range of 10 milliseconds to 1500 milliseconds;
wherein the first bipolar electrode set and the second bipolar electrode set share at least one electrode; and
wherein the at least one electrode that is shared is disposed within the body.
