1. An intravascular device for occluding a patient'"'"'s artery comprising:

  • a) an elongated shaft having a proximal and distal ends and a distal shaft portion which is configured to be advanced through a patient'"'"'s artery having an outer diameter not greater than 0.025 inch;

    b) a first electrode on the distal end of the elongated shaft which has a concave distal face for emission of high frequency electrical energy;

    c) a second electrode on the distal extremity of the elongated shaft spaced proximal to the distal end of the shaft;

    d) a plurality of insulated electrical conductors, each conductor having a distal and electrically connected to one of said electrodes and having a proximal end electrically connected to an electrical connector; and

    e) a source of high frequency electrical power electrically connected to at least one insulated electrical conductor by means of the electrical connector.
