摘要： 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.

摘要： A coagulation system is provided for use in biological tissue. The coagulation system includes a handle, a radiofrequency (RF) generator, and an electrode array. The electrode array includes two or more pair of bipolar electrodes slideably coupled in channels of the handle. The bipolar electrodes electrically couple to the RF generator, and the electrode array is configured to deliver a balanced energy density in a target volume of the biological tissue.

摘要： Methods for performing coagulation necrosis of biological tissue are provided. The methods include configuring electrode arrays to provide balanced energy density in target tissue volumes using two or more pair of electrodes. The electrode array configuration includes at least one of irregular spacing between one or more pairs of electrodes and one or more electrode diameters. The methods further include deploying each electrode of an array at a selected depth in the target tissue volume in accordance with the configuration. Energy is then delivered to the target tissue volume using power sources coupled to the electrodes. The methods control power delivery in response to at least one of elapsed time of delivery, temperatures of the target tissue volume, and impedance levels in the target tissue volume to provide balanced or uniform energy throughout the target tissue volume. The methods generate planes of coagulated tissue.
