DUAL BRACKETED ENERGY DELIVERY PROBE AND METHOD OF USE
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. At least a portion of each trocar is disposed with the at least one probe body. The distance between the first trocar and the second trocar is adjustable between a first position and a second position. Each of the deployed electrodes has an energy delivery surface of a sufficient size to create a volumetric ablation zone between the deployed electrodes. The energy delivery probe is connected to an energy source. At least one cable couples the energy delivery probe to the energy source.
