Steps to generate virtual stent for computational fluid dynamics analysis. (A) An artificial vascular replica of the idealized sidewall-type saccular aneurysm model with a real pipeline embolization device (PED) installed (indicated by a red square). (B) A detailed view of the PED deployed within the silicone aneurysm model. (C) Virtual stent created based on the wire configurations of the real PED.
