Claim 6:
7. A device comprising:
a generator programmed to provide a plurality of predetermined electrical treatment protocols, with at least one of the treatment protocols providing for:
a plurality of bipolar electrical pulses;
delivery of the bipolar electrical pulses at a voltage of up to 5,000 volts;
delivery of the bipolar electrical pulses at a frequency of up to about 500 kHz; and
delivery of the bipolar electrical pulses at a pulse length of at least 10 ns to 1 millisecond;

wherein the generator is configured to be operatively coupled to at least two electrodes;
wherein the bipolar electrical pulses:
comprise a first polarity portion and a second polarity portion, each portion having a square waveform;
are configured to alternate polarity during pulse delivery from the first polarity portion of one polarity to the second polarity portion of the opposite polarity;
are configured with a delay between the first polarity portion and the second polarity portion, wherein the delay is from 1 times the pulse length to 5 times the pulse length;

and
are configured to non-thermally ablate cells of a target area.
