This study evaluated the performance of a centrifugal blood pump designed for the children with heart failure. In this work, to better understand the hemodynamic effects of LVAD outflow-graft anastomosis location, a 3D blood pump model is constructed and patient-specific of ventricular volume is considered. The aim of the research is to observe the impact of the physiological waveform, the periodic...
A mock circulatory loop was constructed to facilitate total artificial heart development. The loop includes many novel features such as a pressure-regulated tank to simulate exercise conditions, controllable systemic and pulmonary vascular resistance to create left-right flow imbalances as seen in postural change and breathing, and a left atrial suction valve. Dual HeartMate II pumps and the BiVACOR®...
The left ventricular assist device (LVAD) is a mechanical device that can assist an ailing heart in performing its functions. The latest generation of such devices is comprised of rotary pumps which are generally much smaller, lighter, and quieter than the conventional pulsatile pumps. The rotary pumps are controlled by varying the rotor (impeller) speed. If the patient is in a health care facility,...
