Abstract:
1. An electrode system for use with a high frequency generator to induce coherent high frequency heat ablation volumes within targeted tissue of a patient, which comprises: at least three electrodes, each including: a distal introducer and a proximal introducer, wherein the distal introducer and the proximal introducer each include a central hole formed therein for selectively receiving a guide needle therethrough, wherein the central holes function to align the distal and proximal introducers with one another, wherein the proximal introducer is movable relative to the distal introducer and is configured to maintain the electrodes therein during movement to insert the electrodes into the tissue, the distal and proximal introducers each include a plurality of arrays of holes formed therein, each array of holes arranged in a linear row, wherein the rows of holes are equally spaced from one another; and a guide needle disposed in the central hole of at least one of the proximal introducer and the distal introducer.
