摘要：A tissue ablation system including numerous components and methods is
described herein for encircling target tissue and generating tissue ablation volumes invarious biological tissues. The biological tissue includes tissue of a variety of organs ofthe human body including the liver, spleen, kidney, lung, breast and other organs, but isnot so limited. The tissue ablation device comprises an energy source and at least onetrocar coupled to the energy source, the trocar having a body, a proximal end, and adistal end. The trocar carries an electrode array that comprises a plurality of electrodes,each electrode of the plurality of electrodes is configured to extend from the trocarwhen moved from a retracted state to a deployed state, and to have at least one radiusof curvature in the deployed state so that the electrode array forms a series of shapedelectrodes in the deployed state.
