“…The linear pulse motor (LPM) designed consists of a pair of primary stators placed above and below a flat secondary mover (pancake design). A pulsatile total artificial heart (TAH) is then constituted of the LPM, two pusher plates, two sac type blood pumps and four Jellyfish valves [17]. The TAH pumps the blood by expanding and compressing the sacs according to the reciprocating motion of the pusher plates attached to the mover.…”

A linear tubular switched reluctance motor is presented. This actuator is devoted to be used as a left ventricular assist device (LVAD). In order to avoid thrombosis, this actuator includes pump and valve functions. By using a St. Jude Medical mechanical valve inside the tubular mover, a pulsatile flow is created in the descending aorta. A linear model of a basic pattern of the actuator based on a reluctance network is developed. Then, a two dimensions finite element method analysis is performed in order to check the analytically calculated performances. Relying on these both models, specific requirements for the design of this kind of motor are discussed.

Abstract² Prolonged and uncontrolled high shear stresses and turbulence can cause hemolysis, while alternating and low-level stresses may contribute to platelet activation and thrombus formation. Such deficiencies are reported for Total Artificial Heart (TAH) systems which are generally not fully capable of dynamic adaptation to sudden pressure and volume changes. This study introduces an adaptive robust controller for a linear motor based TAH (LMTAH) which overcomes such shortcomings. Proposed controller performance is compared with simulated natural heart in normal and stressed physiological conditions. Application of adaptive robust control results in flows with less stress variation and recirculation, thereby reducing the possibility of blood clot formation and hemolysis.Keywords² Artificial heart, adaptive robust control, blood flow, blood pressure I.
