Abstract

Energy delivery systems and methods are provided for use in biological tissue. The energy delivery 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. The balanced energy density delivered by the electrode array results in generation of a hemostatic plane of tissue.
