System and method for ablating tissue
First Claim
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.

Abstract
An electrosurgical system and method for performing an electrosurgical procedure are disclosed. The electrosurgical system includes a high frequency generator to supply energy, the generator including one or more electrical connections. The system also includes one or more instruments configured to be inserted into tissue of the patient'"'"'s body having a hardened tissue volume. The instruments are configured to penetrate the hardened tissue volume to create at one or more orifices defined therein. The instruments are also configured to selectively encapsulate one or more active electrodes that are coupled to the electrical connections. Each of the electrodes has an elongated shaft terminating in an exposed, conductive tip. The electrodes are configured to be inserted into the tissue of the patient'"'"'s body and into the hardened tissue volume through the orifices 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.

7. A method for performing an electrosurgical procedure comprising the steps of:
-
encapsulating at least one active electrode disposed on an elongated shaft with an instrument configured to penetrate a hardened tissue volume;
coupling the at least one active electrode to an electrical energy source, each active electrode including an exposed, conductive tip;
inserting the at least one instrument into the hardened tissue volume to create at least one orifice defined therein;
removing the at least one instrument from the at least one active electrode;
inserting the at least one active electrode into the at least one orifice defined in the hardened tissue volume; and
activating the at least one active electrode to apply energy from the electrical energy source 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. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. An ablation probe, comprising:
-
at least one active electrode each having an elongated shaft, the at least one active electrode being adapted to connect to an electrical energy source;
at least one boring device configured to selectively encapsulate the at least one active electrode, the boring device being configured to penetrate a hardened tissue volume to create at least one orifice defined therein such that, after removal of the at least one boring device, the a at least one active electrode can be subsequently inserted into the orifice and activated 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.
