Claim:
1. An electro-thermal apparatus configured to treat tissue, comprising: an electrosurgical cable having a proximal portion configured to couple to an electrosurgical energy source and a distal portion including a supply line and a return line, the supply and return lines together forming a double helix configuration having a first pitch; and an electro-thermal element having a first conductive trace in electrical communication with the supply line and a second conductive trace in electrical communication with the return line, the first and second conductive traces together forming a double helix configuration having a second pitch different than the first pitch of the double helix configuration of the supply and return lines to provide a thermal resistivity and electro-thermal output that are configured to convert electrical energy provided by the supply and return lines to thermal energy for treating tissue.
