One lumen of the multiple lumen catheter is adapted to deliver contrast agent to the coronary artery to be visualized while a second, and optionally a third, lumen is adapted to limit flow of contrast agent to one or more other locations in the aortic root complex. The invention also includes a method of preparing for coronary angiography using such a catheter.
