Abstract
An intravascular microaxial pump has an integrated configuration that enables both the drive unit as well as the pumping segment to be advanced through a patient's vasculature. The device includes elements that enhance pumping efficiency and performance while minimizing shear and cavitation. Cost reduction is achieved in the reusability of certain components while a manufacturing method reduces the labor involved in the pump's assembly.
