Fluid-structure interaction analysis in Internal Carotid Artery(ICA) are carried out as preparation for validation between the result of numerical simulation and photoelastic stress analysis. In this work, we assume blood vessel as an isotropic elastic medium and the wall's Poisson ratio is 0.45 and Young's modulus is 3.0Mpa. Our study shows various parameter on fluid dynamics of blood flow, such...
In this study, we succeeded in fine construction of the PLCL (poly-L-lactide-cocaprolactone) scaffold with micrometer range resolution using photolithography. PLCL is a biodegradable polymer which is used as a material of the scaffold to reproduce the blood vessel. Photolithography known as a technique of microfabrication was used for the processing of PLCL. By this technique, we fabricated a sheet-like...
In this paper, we propose a method to reproduce fluoroscopic image which is utilized during endovascular surgery process, without using x-raying by introducing augmented reality technique, for constructing an endovascular simulator comprised of an in vitro patient- specific blood vessel model. To reproduce the fluoroscopic image, proposed method firstly matches the refraction index of the blood vessel...
We have been developing scaffolds of three-dimensional (3D) synthetic vascular prosthesis in tailor-made. Human umbilical vein endothelial cells (HUVECs) attached on the inner surface of the scaffold have anticoagulant effects. Asperity structures of the inner surface are important to cell adhesion. It is important to quantify the inner surface asperity condition of the scaffold by observing HUVECs...
