1. A method of treating a vessel at a treatment site, the method comprising:

  • employing an energy-emitting probe, the probe comprising;

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

    an energy element adjacent the distal end, the energy element comprising a generally spherical or toroidal first electrode disposed near the distal end of the shaft and a second electrode located proximally of the first electrode along the elongate shaft;

    accessing the vessel through the skin with a needle and cannula assembly;

    removing the needle from the cannula;

    advancing the probe through the cannula to the treatment site;

    applying energy to the vessel with the energy element, thereby constricting the vessel, wherein the energy is applied to the vessel extravascularly; and

    removing the probe and the cannula.
