Abstract
A method and apparatus are described to provide improved cardiac assist by the use of a new form of intraaortic balloon. A single small balloon may be placed in the ascending aorta close to the aortic valve, such placement being effective to produce a substantially stronger augmentation of heart action than with the use of a longer balloon normally placed, for example, in the descending aorta. Multiple small balloons positioned in the aortic arch, with or without a large balloon in the descending aorta, can be used to provide even stronger coronary flows. The external diameter of the balloons in their inflated condition should in all events never be so great as to block the aorta, even when the latter may become contracted.
