<p>Systems, apparatus, and methods for ablating, sculpting, severing, shrinking, coagulating, or otherwise modifying a target tissue to be treated. In a method for treating a target tissue, an active electrode terminal (42) of an electrosurgical probe (20) is positioned in at least close proximity to the target tissue. A high frequency voltage is then applied between the active electrode (42) and a return electrode (112), wherein, the high frequency voltage is sufficient to volumetrically (ablate), sever, or modify at least a portion of the target tissue. The probe (20) comprises an electrode assembly including an electrode support (44) and at least one active electrode terminal (42) arranged within the electrode support (44), the electrode support (44) having a suction cavity, and each active electrode terminal (42) having an electrode lumen therein, the electrode lumen in communication with the suction cavity. Unwanted materials may be aspirated from a surgical site via the electrode lumen.</p> |
