1. A method for thermo-electrical cutting of biological tissue comprising:

  • applying a low duty-cycle pulse waveform to a cutting electrode, wherein the cutting electrode has a peak temperature during application of the pulse waveform of greater than 100°

    C. and an average temperature during application of the pulse waveform of less than about 50°

    C.; and

    cutting the tissue with the cutting electrode during application of the low duty-cycle pulse waveform.
