1. An electrode system for delivering an electrical signal to a first tissue of a patient'"'"'s body, said electrode system comprising:

  • a lead; and

    an electrode coupled to said lead, comprisinga stimulation portion adapted to be coupled to said first tissue and adapted to deliver an electrical signal to said first tissue;

    a dissipation portion that is not adapted to interface with said first tissue, wherein said dissipation portion is branching off the lead along a distal branch, wherein said dissipation portion is adapted to interface with a second tissue, said dissipation portion capable of dissipating thermal energy by receiving at least a portion of an induced current on the lead; and

    an insulator surrounding at least a portion of said dissipation portion, wherein said insulator is a thermal insulator for at least partially attenuating dissipation of said thermal energy, wherein said insulator further comprises an electrical insulator.
