Abstract

The development of a numerical criterion to evaluate the stress on models of vasculature has applications in evaluation of human skills, robots and medical tools. This criterion will enable better medical training for endovascular surgery and the development of better medical techniques and tools. We propose to use the stress produced by human blood pressure simulation in the wall of the model of vasculature as this criterion; and to measure the principal component of stress magnitude using photoelastic effect. For that we simulated human blood pressure with a 5.6% of average error, we developed a shielded urethane model of vasculature enabling water circulation and avoiding plastic deformation with pressures below 182 mmHg. We developed software to calculate the stress of the model wall. Stress produced by human blood pressure simulation and a guide wire were compared numerically in four ranges.
