Fabrication of Transparent Arteriole Membrane Models

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 fabrication method for transparent arteriole membranous model which has circular cross section smaller than 500 mum in diameter. Fabrication method of the model as well as evaluation result of the molding material is reported.
