Classification: CPC A | IPC A

Claim 0:
1. A method of treating tissue, the method comprising:
using a number of electrodes, delivering a total number of electrical pulses to a target region by:
activating a number of pairs of the electrodes in a number of cycles;
wherein the activating is performed a number of times that equals the total number of electrical pulses, divided by the number of pairs of electrodes, divided by the number of cycles;
wherein the activating is performed 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;

whereby electrical energy is strategically distributed to sub-regions within the outline of the target region to treat tissue while mitigating one or more of thermal effects, thermal damage, potential for Joule heating, or delivery of electric current to tissue of the target region; and
wherein at least one of the electrodes is a surface electrode and at least one of the electrodes is a needle electrode.
