Today, Mechanical Circulatory Support (MCS) is indispensable for treatment of patients with serious heart failure, not only the adult patients but also infants and children. The MCS can be utilized for applications including destination therapy (DT)/bridge to transplantation (BTT)/recovery oriented assistance with new medical treatment. In Japan, however, we do not have MCS devices suitable for Pediatric circulatory support. In this study, we have developed a tiny rotary blood pump (TinyPump VAD) with extremely small priming volume intended for circulatory support in children and infants. TinyPump VAD consists of a 6-vane impeller integrated with a direct drive motor with its diameter and height being 58mm and 35mm, and the priming volume of 6.5mL. The TinyPump VAD has favorable features as an implantable Pediatric MCS.
