Abstract
An intra-arterial cardiac support system including multiple balloons for placement in the descending aorta with one balloon serving as a pumping balloon and one or more balloons serving as valve balloons, at least one of the valve balloons being positioned distal to the natural heart. The balloons are individually inflated and deflated to provide for sequential pumping action, with the sequence operating in timed relation to the sytstole and diastole of the natural heart.
