Abstract
An electrosurgical electrode comprises a generally L-shaped metal member comprising an electrically-insulated, shank part for mounting in a standard electrosurgical handpiece, and a generally straight part divided into first, second, and third sections, the first of which is electrically-insulating and the third of which is bare and terminates in a pointed end. The third section has an angled cross-section, such as rectangular, square or triangular, and more easily pentrates dense tissue targeted for radiofrequency thermal ablation. An important application is volumetric shrinkage of tongue base tissue, for example, for treating sleep disordered breathing.
