Multiple Treatment Zone Ablation Probe

摘要

An energy delivery probe and method of using the energy delivery probe to treat a patient is provided herein. The energy delivery probe has at least one probe body having a longitudinal axis and at least a first trocar and a second trocar. Each trocar comprises at least two electrodes that are electrically insulated from each other, and each electrode is independently selectively activatable. An insulative sleeve is positioned in a coaxially surrounding relationship to each of the first trocar and the second trocar. The probe also has a switching means for independently activating at least one electrode. The method involves independently and selectively activating the first and second electrodes to form an ablation zone, then repeating the ablation by delivering energy to a second set of electrodes, producing one or more overlapping ablation zone, and eliminating the need to reposition the ablation probes.

1. An energy delivery probe for treating a patient, comprising:
a first shaft and a second shaft, each having a proximal end and a distal end, wherein the distal end is capable of piercing tissue, wherein each shaft comprises at least a first electrode and a second electrode that are electrically insulated from each other. wherein each electrode is independently selectively activatable, and an insulative sleeve positioned in a coaxially surrounding relationship to at least a portion of each of the first shaft and the second shaft.
