Claim 13:
14. A method of treating a tissue with electrical energy while mitigating thermal damage to the tissue, the method comprising:
distributing a total number of electrical pulses to the tissue by way of a plurality of electrode pairs over a plurality of cycles,
such that each electrode pair is activated to receive one or more pulse train during each cycle of the plurality of cycles, and
such that within at least one cycle:
first and second electrode pairs are activated in sequence; and
third and fourth electrode pairs are activated in sequence;

wherein the first electrode pair comprises different electrodes than the second electrode pair and the third electrode pair comprises different electrodes than the fourth electrode pair; and
wherein at least one of the electrodes of one or more of the electrode pairs comprises one or more surface electrodes and at least one of the electrodes of one or more of the electrode pairs comprises one or more needle electrodes.
