<p>Apparatus (20) and a method for cauterizing and/or removing or debulking tissue located on the surface or within the body of a living being. The apparatus (20) comprises a catheter having a distal end portion at which a working head (24) is located. The working head (24) is arranged to be moved, e.g., rotated, repeated by a drive system (40) including an electrically conductive cable (46). The cable (46) is connected between the working head (24) and one electrode of an electrosurgical power supply (30). The other electrode of the supply is connected to a plate arranged to engage a portion of the being's skin. The working head (24) is arranged to be located adjacent the biological material and to be rotated at a relatively high speed to sweep a localized intense electrical current (e.g., arc) across a portion of tissue located immediately adjacent the working head (24). The repeated movement of the working head impacts the tissue to debulk it.</p> |
