Abstract:
1. An electrosurgery system comprising: a catheter including one or more active electrodes adapted to be positioned adjacent biological tissue at an in vivo treatment site in a patient and to deliver electrical energy to the biological tissue; and a dispersive electrode assembly including a conductive element having a first end and a second end, the conductive element comprising a single continuous sheet of conductive material, the dispersive electrode assembly configured to completely surround a waist of the patient such that, when the dispersive electrode assembly is completely surrounding the waist of the patient, a first surface of the conductive element wraps completely around, and is in contact with, the waist and the first end of the conductive element is adjacent the second end of the conductive element; wherein the dispersive electrode assembly comprises a non-conductive structure, having a first end region and a second end region, coupled to a second surface of the conductive element to support the conductive element; and wherein the dispersive electrode assembly further comprises a fastening mechanism, provided on the non-conductive structure, to secure the dispersive electrode assembly around the waist, wherein, when the dispersive electrode assembly is completely surrounding the waist of the patient, the end regions of the non-conductive structure overlap, and the fastening mechanism holds the overlapping end regions together.
