Abstract
The present invention is an intra-aortic circulatory enhancing apparatus for use in human patients to improve blood flow to other arteries continuous with the aorta of the patient. The apparatus comprises an internal inflation means located within the aorta of the patient and an external inflation means located outside of the patient. The internal inflation means can be an internal balloon coupled to a hollow extent which is operatively coupled to a blood communication means. The blood communication means can be a first hollow catheter tube in one embodiment. The external inflation means can be an external balloon coupled to a hollow extent running through the center of the balloon and continuous with a second hollow catheter tube. The blood communication means is coupled to the internal and external inflation means, allowing blood within the aorta to communicate with the secondary inflation means.
