Intra-aortic balloon pump

It consists of a cylindrical polyurethane balloon that sits in the aorta, approximately 2 centimeters (0.79 in) from the left subclavian artery.

Systolic deflation decreases afterload through a vacuum effect and indirectly increases forward flow from the heart.

Placing the balloon too distal from the aortic arch may induce occlusion of the renal artery and subsequent kidney failure.

[2][3] The first publication of intra-aortic balloon counter-pulsation appeared in the American Heart Journal of May 1962; 63: 669-675 by S. Moulopoulos, S. Topaz and W.

[citation needed] The device and the balloons were then developed for commercial use between 1967 and 1969 heart surgery by William Rassman at Cornell Medical Center and were manufactured by Datascope Corporation in 1969.

[8] The first clinical implant was performed at Maimonides Medical Center, Brooklyn, N.Y. in June 1967 by Dr. Adrian Kantrowitz and Dr. Steven Phillips.
