    Abstract: A method of treating abnormal tissue within a patient includes positioning a delivery cannula within the patient, the delivery cannula having a first electrode disposed on its distal end; introducing an ablation probe through the cannula and out an open distal end thereof, so that a second ablation electrode carried on the ablation probe contacts abnormal tissue within the patient; conveying ablation energy between the first and second ablation electrodes to ablate the abnormal tissue; and introducing a separate medical element, whether a device or a therapeutic agent, through the cannula before or after the ablation process.

    Abstract: A tissue ablation system comprises an ablation source, such as an RF ablation source, configured for generating a common power signal, and a power multiplexor configured for splitting the power signal into first and second power signals, substantially attenuating the second power signal relative to the first power signal to create nominal and attenuated power signals, and sequentially delivering the nominal power signal to each tissue ablation probe, while delivering the attenuated power signal to the remaining ablation probes to which the nominal power signal is currently not delivered.

    Abstract: A tissue ablation probe is provided. The probe comprises a proximal electrode element, which includes a proximal electrode stem and a deployable proximal electrode array, and a distal electrode element, which includes a distal electrode stem and a deployable distal electrode array. The probe is configured, such that a majority of electrical energy conveyed between the proximal and distal electrode elements is conveyed between distal termini of the electrode arrays, whereas a relatively small amount of the electrical energy is conveyed between the electrode stems. One or more of the electrodes on the arrays may be optionally insulated to further enhance the electrical characteristics of the arrays.
