ABSTRACT:
A catheter and fluid pumping apparatus and the method for bypassing portions of the heart to temporarily reduce the work load on the heart muscle. A double tube catheter is introduced into the femoral vein or artery and is advanced into the ventricle where blood is drawn and mechanically pumped back into the heart at a position downstream, such as the aorta or the pulmonary artery. The desired cardiac circulation can be maintained while relieving the load on the heart muscle to enable it to rebuild its strength.
