Abstract
A method and apparatus for indirectly infusing the coronary arteries involves insertion of a relatively large tubular member into the left ventricle to maintain blood flow from the left ventricle into the aorta. An isolated chamber within a segment of the aorta encompassing the opening to the coronary arteries is formed by inflating a pair of doughnut-shaped balloons attached at opposite ends of the tubular member. A catheter extends axially through the tubular member and includes a passage for infusing a treatment material into the isolated chamber. The treatment material is subsequently drawn into the coronary arteries which form the only exit from the isolated chamber.
