CH-VAD^®

The implantable CH-VAD^® left ventricular assist system (LVAS) is a new-generation fully magnetically levitated ventricular assist device (LVAD). It uses a rotating-blade rotor to create negative pressure at the center of the pump, drawing blood from the patient's left ventricle and delivering it to the ascending aorta. This generates blood flow in the circulatory system, enabling the pump to work in coordination with the natural heart. 

CH-VAD^® LVAS is composed of implantable and external components. The pump, as the core component, is a special and precise centrifugal pump. The product is so compact that it can be held in the palm of the hand. Its impeller is supported by magnetic suspension without bearing rotating under the drive of a brushless DC motor. The system controller is responsible for power management, blood pump status monitoring and adjustment, and providing the user interface. The combination of hardware and software of the whole system meets the requirements of high reliability, safety, and electromagnetic compatibility.
