Abstract

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.

Claims

1. A probe device comprising:
