1. A method for treating a vessel with septal perforators, comprising:

  • providing an elongated catheter having an expandable member positioned thereon, tracking guide wire disposed within a tracking guide wire lumen and a positioning guide wire disposed within a positioning guide wire lumen, said positioning guide wire lumen having a distal opening formed in said catheter adjacent said expandable member;

    providing a torquing member attached to both said tracking guide wire lumen and said positioning guide wire lumen;

    positioning an expandable stent having a side aperture on said catheter so as envelop said expandable member and such that said distal opening of said positioning guide wire is aligned with a portion of said aperture;

    advancing said catheter through a vessel having septal perforators along said tracking guide wire to a position wherein said stent is substantially longitudinally aligned and wherein said positioning guide wire lumen opening is generally radially aligned with said septal perforators;

    advancing said positioning guide wire so as to emerge from said distal opening in said positioning guide wire and enter one of said septal perforators;

    further advancing said catheter in a distal direction so as to cause said catheter and stent to rotate into substantial alignment with said septal perforators by torque created by the positioning guide wire and tracking guide wire which is transferred to the catheter by said torquing member; and

    expanding said expandable member to expand said stent.
