Patent ID: 7985220

Claim:
An electrosurgical system, comprising: a generator adapted to generate electrosurgical energy for treating tissue, the generator including at least one active output terminal that supplies energy to the tissue, the at least one active output terminal operatively connected to at least one supply line, the generator also including at least one return output terminal that returns energy from the tissue, the at least one return output terminal operatively connected to at least one return line; an electrosurgical instrument operatively connected to the at least one supply line; at least one return electrode operatively connected to the at least one return line; and an electrosurgical cable including the at least one supply line and the at least one return line, a portion of the at least one supply line and a portion of the at least one return line being wound in a double helix such that the electrical field along the length of the cable is reduced, wherein at least one parameter of the wound portion of the cable and at least one parameter of an unwound portion of the cable are configured to control the electrical field coupling between the at least one supply line and the at least one return line.
