1. A method of treating a target region of a tissue, the method comprising:
disposing a plurality of electrodes near the target region; and
activating a generator to deliver electrical pulses to the target region via the plurality of electrodes, wherein:
a total number of electrical pulses to be applied between the plurality of electrodes is divided into subsets of at least 10 electrical pulses,
each subset is sequentially applied between the plurality of electrodes until all of the electrodes have been activated to define a pulse cycle, and
the pulse cycles are repeated until the total number of electrical pulses are applied,
wherein a delay of between 250 milliseconds and 15 seconds is applied between each electrical pulse; and
wherein a delay of between 5 seconds and 10 minutes is applied between each pulse subset.
