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.

可植入的心室辅助设备（VAD）已经应用于欧洲，美国和日本的临床实践。在不久的将来，VAD植入的数量预计将成为心脏移植的数量。这项研究与利用磁性轴承技术的可植入离心血泵系统有关，该系统可以实现VAD的高耐用性和高生物相容性。在本报告中，在机械和电气断层的情况下，可以估算血流和血液粘度的多功能，高度可靠和紧凑的VAD的实现，这些vad具有备份功能，可以植入儿童体内。
