An articulated, intravascular pump having multiple pump sections (250, 260, 270, 280, 290) linked together for relative motion and driven by a common drive cable (140) is disclosed. Each pump section is relatively short, so that it may easily pass artery. Disposed in the aortic arch during operation, the pump includes means (135) for selectively directing the discharge blood flow from each pump section to inlets of major arteries branching from the arch. |
