A Device and method are provided to split a single chambered IAB device into at least two IAB distinct chambers, that work in conjunction with each other, each being smaller than the single chamber, but the combination of the two chambers may be greater than the single chamber.

DETAILED DESCRIPTION The present invention involves the use of two or more intra-aortic balloons which may be of different volume sizes used in conjunction with each other to reduce the overall size of the puncture site of insertion of each IAB balloon into the patient.
The volume size of each balloon may also be different.
The balloons, when in use, are in position, typically in the descending aorta of the patient, to displace a pre-determined volume by simultaneously inflation of said balloons.
While it is preferred that each balloon be inflated by the same balloon pump, this is not necessary.
In the following manner the total volume size of the combined balloons through mixing and matching various sizes of balloons can be almost endless and limited only by the size of the patient's aorta.
