Interstitial cauterization of tissue volumes with electrosurgically deployed electrodes

摘要

Apparatus system and method for cauterizing a volume of tissue wherein electrode assemblies are deployed from the forward end region of an instrument in conjunction with an electrosurgical cutting activity. Upon deployment to one or more deployed orientations, the electrodes assemblies are made biactive and the cauterization of tissue is carried out in a bipolar fashion. Following the procedure, the electrode assemblies are retracted toward the instrument and the instrument is withdrawn from the tissue region.
