- Computational simulation of intravascular-treatment stent development in curved arteries using corotational beam elements
抄録
<p>The intravascular-treatment stent for cerebral aneurysms is one of the brained stent-mesh devices and used to reduce inflow into aneurysms or assist the coil embolization. Clinical observations reported stent deployment into the curved arteries may cause incomplete stent expansion but this mechanism is still an open question, and thus understanding of the mechanical characteristics of the stent is hopeful. The present study aims to represent mechanical characteristics of the stent in the deployment process in curved arteries by a computational simulation. The stent was modeled to be a set of metallic wires which obeys Euler-Bernoulli beam theory and mechanical state of the stent was represented by solving the equation of motion based on the corotational formulation with considering multiple contacts. Present results successfully represented the mechanical behavior of the stent in the deployment process into catheter and curved arteries. It also demonstrated the stent expansion in the arteries results in the release of bending energy in the wires constituting the stent.</p>
