ABSTRACT:
A method and device for assisting cardiocirculation includes inserting a cannula in the axillary or subclavian artery, which cannula has associated therewith a blood pump, a balloon pump which responds to EKG signals, and a heart pacer which triggers the EKG and is capable of responding to and reversing ventricular extra systoles, and maneuvering the cannula into the aorta and left ventricle. The device functions by directly unloading surplus blood from the left ventricle of the heart, thereby reducing the work load of the heart so that it may in time recover from a serious if not critical insult.
