Abstract
A multiple lumen catheter specifically adapted for selective visualization of one or the other of the coronary arteries. 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.
