Abstract
This device relates to an improvement on mechanical enhancement of the pumping action of the human heart, which is achieved by an external venting source, such as a pump joined to an instrument insertable into a patient's heart or aorta and serving to vent excessive gases from the heart, thereby improving brain and lung functions in a closed-loop fashion, by improving the pumping ability of the human heart.
