“…The abundance of research already available and the complexity of the axial blood pump design streamline the design process and enabled us to focus our effort. [34][35][36][37] We found that widening the trailing end of the diffuser blades and also elongating the diffuser blades aided in reducing blood recirculation. We also found that increasing the axial gap between the end of the inducer blades and the beginning the impeller blades led to a lowering a scalar stress levels at the leading edge of the impeller blades.…”

“…The fluid dynamics of the blood flowing from one bladed region to another is also impacted by the design of the blades in one domain versus another. The abundance of research already available and the complexity of the axial blood pump design streamline the design process and enabled us to focus our effort 34‐37 . We found that widening the trailing end of the diffuser blades and also elongating the diffuser blades aided in reducing blood recirculation.…”

Thousands of babies are born each year with congenital heart defects that necessitate surgical intervention within the first few days-to-years of life. 1 A subgroup of these infants contend with complex cardiac defects and debilitating malformations of their heart chambers, valves, or connecting vessels. 2 Patients born with severe and multiple cardiac defects generally undergo multiple open-heart surgeries and are known to develop early onset congestive heart failure (CHF).

This study presents the design of a magnetically levitated (maglev) axial magnetic flux brushless direct current motor (AF-BLDC) for an axial blood flow ventricular assist device (VAD). It has three phases, twelve salient stator poles, and eight rotor magnet poles. It is designed in miniature size. Twin AF-BLDC motors are placed in the VAD symmetrically and rotors are coupled to the pump from two sides. The stator and rotor of the proposed motor are designed with a hole since magnetic flux does not pass through the central part. Pump impellers may be placed in this hole for larger pump chamber volume and lower speed. The motor has a passive magnetic bearing and does not involve contact and friction to minimize blood damage. Bearing magnets ensure magnetic suspension. Axial magnetic fluxes are parallel to blood flow direction, thus minimizing penetration of magnetic field into blood. Magnetic parameters, axial pull force, and torque of the proposed motor have been analyzed by the 3-dimensional finite elements method (3D-FEM) to confirm the motor design. Solutions are compared with maglev and non-maglev designs.
