Abstract

The main objective of this study is to predict the behavior of the guidewire and its performance in a vasculature prior to the procedure. Method: We have developed a 2D multibody model in which a guidewire is considered as a set of small rigid segments connected to each other by revolute joints. These joints have two degrees of freedom to allow rotation. Linear torsional springs and dampers are applied in each joint to account for the elastic properties of the guidewire; we have measured the elastic properties for two commercially available guidewires (Hi-Torque Balance Middleweight Universal II-Abbot and Amplatz Super Stiff, Boston Scientific) and these are used in the model. We have investigated the effect of the bending stiffness of the guidewire and of the friction between guidewire and vasculature on its behavior. We validated the results with actual movement of the guidewires in a simple phantom model. Results: Behavior of a guidewire in a vasculature was predicted using the developed model. The results of both simulation and experiment show that the translational behavior of a guidewire is influenced by its mechanical properties and by the friction between the guidewire and vasculature. Conclusion: We compared the tip trajectory for two commercial guidewires in one vasculature geometry. In future, this kind of knowledge might support not only the interventionist in choosing the best suitable guidewire for a procedure but also the designer to optimize new instrument to have the desired behavior.
