From the moment of creation to the moment of death, the heart works tirelessly to circulate
blood, being a critical organ to sustain life. As a non-stop** pum** machine, it operates …

Estimation of instantaneous flow in rotary blood pumps (RBPs) is important for monitoring
the interaction between heart and pump and eventually the ventricular function. Our group …

Introduction: This review explores the Starling-like physiological control method (SLC) for
rotary ventricular assist devices (VADs) for severe heart failure. The SLC, based on …

The use of long-term mechanical circulatory support (MCS) for heart failure by means of
implanted continuous-flow left ventricular assist devices (cf-LVADs) will increase, either to …

There is significant interest in the development and application of variable speed impeller-
pump type ventricular assist devices designed to generate pulsatile blood flow. However, no …

BACKGROUND: Direct measurement of blood flow output has been incorporated into
ventricular assist devices (VADs), but long-term reliability of the additional device …

Objective: Continuous Flow Left Ventricular Assist Devices (CFLVAD) are circulatory support
devices that are implanted in patients with end-stage heart failure. We developed a novel …

Objective: Currently available ventricular assist devices provide continuous flow and do not
adapt to the changing needs of patients. Physiological control algorithms have been …

Controller algorithms are an important feature for assessment of ventricular assist device
performance. Flow estimation is one algorithm implemented in the HeartWare continuous …

We propose dynamical models for pulsatile flow and head estimation in an implantable
rotary blood pump. Pulsatile flow and head data were obtained using a circulatory mock …
