1. A method for performing intravascular nerve modulation, the method comprising:

  • providing a nerve modulation system comprising;

    an elongate shaft having a proximal end region and a distal end region;

    a first transducer disposed adjacent the distal end region; and

    a second transducer disposed adjacent to the first transducer;

    advancing the nerve modulation system through a lumen such that the first transducer is adjacent to a first target region;

    supplying a first current to the first transducer to generate a first acoustic energy that is directed to the first target region such that a temperature of the first target region is raised to a first temperature that is sufficient to generate a thermal nerve block; and

    supplying a second current to the second transducer to generate a second acoustic energy different from the first acoustic energy, said second acoustic energy directed to a second target region adjacent to the second transducer such that a temperature of the second target region is raised to a second temperature that is greater than the first temperature and is sufficient to perform nerve modulation.
