1. Apparatus for hemostatically cutting tissue, the apparatus comprising:

  • first and second scissor blades arranged to contact one another along a cutting length;

    a layer of insulative material disposed for the cutting length to electrically isolate the first and second scissor blades from one another;

    means for joining the first and second scissor blades together so that at least the first scissor blade moves relative to the second scissor blade in a scissors-like cutting motion, wherein the first and second scissor blades close together for shearing tissue located therebetween; and

    means for electrically coupling a high frequency alternating-current waveform to the first and second scissor blades.
