Abstract
A system and method for transmitting electrosurgical energy from a generator to an electrosurgical instrument are provided. The electrosurgical system includes a generator adapted to generate electrosurgical energy for treating tissue. The generator includes one or more active output terminals which supply energy to the tissue. The active output terminals are operatively connected to one or more active leads. The generator also includes one or more return output terminals which returns energy from the tissue. The return output terminals are operatively connected to at least one return lead. The system also includes an electrosurgical instrument operatively connected to the one or more active leads and one or more return electrodes operatively connected to one or more return leads. The system further includes an electrosurgical cable including one or more active leads and one or more return leads. The one or more active leads and one or more return leads are wound in a double helix fashion such that the electrical field along the cable is mitigated along the length thereof.
