An in vitro patient-specific vasculature model of human total arterial system, for simulating endovascular intervention for evaluating surgical instruments and preliminary simulating surgical procedures, is presented. Presented vasculature model precisely reproduce the thin membranous configuration artery, in addition to its physical characteristics such as elastic modulus and friction coefficient. Applying photoelastic method, proposed simulator visualize stress condition on vasculature wall arisen from surgical operations and blood streaming. With proposed method, stress condition on vascular wall represented by two principal stresses is clearly visualized on vascular fringe as rainbow-colored photoelastic stress pattern, and the quantitative stress is analyzed from that pattern. The accuracy of stress analysis is evaluated by tensile test using cylindrical model. Consequently, it should be valuable for various applications not only surgical simulations but also hemodynamic studies and pathological studies.
