摘要:
A medical probe assembly, tissue treatment system, and method are provided for ablating tissue. The probe assembly comprises an elongated member and electrode elements mechanically coupled to the distal end of the elongated member. The electrode elements are configurable as two bipolar electrode pairs with a common electrode element. At least one of the electrode elements comprises a plurality of electrodes (such as, e.g., needle electrodes) radially extendable from the elongated member. An ablation source, such as a radio frequency source, can be connected to the probe assembly in order to convey ablation energy to the electrode pairs, either simultaneously or sequentially.

摘要:
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.
