In cardiovascular medicine, the clinical use of artificial hearts (or blood pumps) as a bridge to heart transplantation or as a form of end-stage treatment to support patients with advanced heart disease has become an accepted clinical practice. The number of patients suffering from heart disease requiring a heart replacement operation is quite large, but the serious shortage of transplant donors makes the treatment of most heart disease patients difficult, and even loses the chance of survival. Therefore, the development of a high-performance heart pump is of great significance.
Ventricular assist devices may use a blood pump to power the patient's blood, thereby pushing the blood to high pressure. One example of a ventricular assist device is a Left Ventricular Assist Device (LVAD). The LVAD is connected to the left ventricle of the patient's heart where oxygenated blood enters the LVAD through the blood inlet of the LAVD. LVAD then provides momentum to the blood. A blood outlet through the LVAD is connected to the aorta of the patient; the pumped blood may re-enter the patient point circulatory system. Common LVADs, however, currently include positive displacement pumps and rotary pumps.
