1. An intravascular catheter assembly for performing an intravascular procedure within a patient'"'"'s coronary vasculature, comprising:

  • a) an elongated guiding catheter having a proximal end, a distal end, a port in the distal end and an inner lumen extending therein to and in fluid communication with the port in the distal end; and

    b) an elongated intravascular catheter slidably disposed within the inner lumen of the guiding catheter having a proximal end and a distal end, a first guidewire port in the distal end, a distal shaft section which is configured to be disposed entirely within the patient during the procedure, which extends proximally form the first guidewire port and which has a first transverse dimension in a first direction substantially greater than a second transverse dimension perpendicular to the first direction, a second guidewire port located within the distal shaft section spaced a distance of at least 10 cm from the distal end and a substantial distance from the proximal end, an inner lumen extending within the distal shaft section between the first and second guidewire ports.
