HIGH PERMITTIVITY ELECTROSURGICAL ELECTRODE COATING
A coating for the electrode of an electrosurgical instrument that increases the capacitance of the electrode. The coating comprises a high permittivity material such as barium titanate, lead zirconate titanate, calcium copper titanate, or a conjugated polymer. The coating may have a thickness of 0.0016 inches and can be included with one of more insulative layers.
