In order to verify the effects of hemodynamics on coil compaction and migration, we analyze the forces and displacements on the coil bundle using a computational method. Lateral aneurysms partially filled coils are modeled, and blood flow fields and coil deformations are simulated considering fluid and solid interaction. Effects of coil locations and parent vessel geometry are also investigated. The results showed that mean coil displacements were larger at the distal neck coil location, which implied that coil at the neck might experience more migration. Parent vessel geometry affected the mean coil displacement negligibly, but it influenced mean pressure force profiles on the coil surface. Pressure forces were higher in the straight parent vessel model during diastole, which might promote coil compaction. 2012-10-15T04:35:37Z 2012-10-15T04:35:37Z 2012-02-27 Working Paper p. 292-295 978-145771989-9 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6179023 http://hdl.handle.net/123456789/21357 en Proceedings of the International Conference on Biomedical Engineering (ICoBE 2012) Institute of Electrical and Electronics Engineers (IEEE)
