1. A system for generating a guided current path in a skin volume, said system comprising:

  • (a) at least one transducer configured to focus ultrasound energy at least one focal volume in the skin and heat said volume so as to raise the volume electrical conductivity;

    (b) at least a pair of RF electrodes configured to deliver RF energy to the same focal volume; and

    (c) a control unit configured to enable an RF current generated by the RF energy to flow between the pair of RF electrodes through a central part of the heated focal volume,wherein the parameters of the RF energy are selected from the group consisting of a frequency of an RF voltage between 100 KHz and 100 MHz, an intensity of the RF voltage, and a duration of the RF energy, andwherein the ultrasound energy has a frequency between 500 KHz and 50 MHz.
