  • Method and apparatus for electromagnetic ablation of biological tissue
    Publication number: 20070055225
    Abstract: Apparatus and methods suitable for electromagnetic ablation of targeted tissue provide for improved control over ablation size and shape. In various embodiments, a plurality of dispersive electrodes may be arranged in a circumferential manner in close proximity to a targeted tissue region. The dispersive electrodes may be individually controlled to alternately enable/disable the electrodes to provide for different current paths between an active electrode and one or more of the dispersive electrodes. Other embodiments are described and claimed.
