[Axial micro-pump system of assisted circulation]

An assisted circulation system having a HART-02 axial-flow micropump has been developed. The diameter of the micropump is 7 mm and its length is 20 mm, which allows it to be introduced into the ascending aorta through a peripheral artery. The system has a good biocompatibility, a low hemolysis and its productivity is as much as 3.5 liter/min.
