Abstract
An articulated, intravascular pump having multiple pump sections linked together for relative motion and driven by a common drive cable is disclosed. Each pump section is relatively short, so that it may easily pass through bends in an insertion catheter, the iliofemoral artery and the aorta artery. Disposed in the aortic arch during operation, the pump includes means for selectively directing the discharge blood flow from each pump section to inlets of major arteries branching from the arch.
