AIP Advances, 2017 We propose a position control method for a helical magnetic robot (HMR) that uses the rotating frequency of the external rotating magnetic field (ERMF) to minimize the position fluctuation of the HMR caused by pulsatile flow in human blood vessels.

Simulation of Pulsatile Flow in Cerebral Aneurysms: From Medical Images to Flow and Forces [PDF]
, 2012 In this chapter we present a numerical model for the simulation of blood flow inside cerebral aneurysms. We illustrate the process of predicting flow and forces that arise in vessels and aneurysms starting from patient-specific data obtained using ...

Cerebrovascular Compliance Within the Rigid Confines of the Skull
Frontiers in Physiology, 2018 Pulsatile blood flow is generally mediated by the compliance of blood vessels whereby they distend locally and momentarily to accommodate the passage of the pressure wave.

Microfluidic Modeling of Macrophage‐Induced Cardiac Inflammation Using NF‐κB Reporter Cardiomyocytes
Advanced Healthcare Materials, EarlyView.A cardiac inflammation model was developed to enable real‐time analysis of macrophage‐cardiomyocyte interactions using NF‐κB‐reporter cardiomyocytes and a microfluidic co‐culture system. A MATLAB‐based model was implemented to optimize cell density and medium resupply based on TNFα diffusion kinetics. Activation thresholds and stress responses in NF‐κB‐
