1. An electrosurgical system, comprising:

  • a high frequency generator including at least one electrical connection; and

    at least one instrument configured to be inserted into tissue of a patient'"'"'s body having a hardened tissue volume and configured to penetrate the hardened tissue volume to create at least one orifice defined therein, the instrument configured to selectively encapsulate at least one active electrode;

    the at least one active electrode coupled to the at least one electrical connection and having an elongated shaft terminating in an exposed, conductive tip, the at least one active electrode configured to be inserted into the tissue of the patient'"'"'s body and into the hardened tissue volume through the at least one orifice to subsequently apply energy from the high frequency generator to the exposed, conductive tip to induce a coherent heating effect in the hardened tissue volume from power deposition therein thereby producing a heat ablation volume in the hardened tissue volume.
