We proposed a fabrication method for multiscale transparent arteriole and capillary vessel models and demonstrated the fabrication of microchannels with circular cross sections ??10 - 500 ??m. First, we demonstrated fabrication of ??10 - 500 ??m arteriole and capillary vessel block models using photolithography. The circularity of fabricated ??10, 50, and 500 ??m microchannels were 84.0%, 61.5%, and...
We made transparent arteriole membranous models by using grayscale lithography. We employed a sacrificial model made of WAX and PVA mixture as a novel molding material. Our goal is to complement previous surgical simulators for practice and rehearsal of medical treatments. Since block vessel models cannot recreate moderate compliance which is similar to that of the real blood vessel, here we propose...
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...
