Abstract
A tissue ablation device and method for tissue ablation are described. The tissue ablation device comprises an energy source and an introducer coupled to the energy source, the introducer having a body, a proximal end, and a distal end. The introducer carries an electrode array that comprises a plurality of electrodes, each electrode of the plurality of electrodes is configured to extend from the body of the introducer when moved from a retracted state to a deployed state. The electrode array is designed to encircle a portion of a target tissue when the electrodes are extended into the deployed state and to form a relatively spherical shaped ablation pattern in a tissue volume surrounding the target tissue when energized by the energy source.
