| Research Abstract |
Implantable Ventricular Assist Devices(VAD) have already been applied to clinical practices in Europe, the United States and Japan. In the near future, the number of VAD implantations is expected to become more than the number of heart transplants. This research is related to implantable centrifugal blood pump systems utilizing magnetic bearing technology, which can achieve high durability and high biocompatibility of the VADs. In this report, the realization of multifunctional, highly reliable and compact VADs, which can estimate the blood flow and the blood viscosity, have backup functions in the case of mechanical and electrical faults, and can be implanted in children's bodies, are discussed.
