Abstract
A surgical device includes a return electrode, an active electrode, and an insulating region adjacent to the active electrode. A rasping surface is provided by either the active electrode or the insulating region. Another surgical device includes an adapter configured to couple to a generator and to convert monopolar output from the generator into bipolar output. A method of applying electricity to tissue includes bringing a surgical device into close proximity with tissue and applying electricity to the tissue using the surgical device.
