Abstract
An apparatus for treating a solid tumour to destroy tumour. It has a radio frequency (RF) probe with a distal portion which has mechanically rigid electrodes which when deployed form an electrical bridge circuit with each electrode component being electrically insulated. The deployed electrodes define a region within which a return path for a radio frequency current can be created such that the current is transmittable with more uniform distribution between a pair of opposite and parallel electrodes via the return path. The electrodes are provided with a switch to turn the electrodes on and off in order to change the shape and position of the return path to provide a desired heating effect on the solid tumour when situated within the region.
