Finite element modeling and simulation of the implantation of braided stent to treat cerebral aneurysm

Blog Article

Braided stents were widely used to treat cerebral aneurysms and computational fluid Porcelain Heart dynamics (CFD) was used to evaluate the therapeutic effects.But the aneurysm-artery geometry used in CFD were usually undeformed which is inconsistent with clinical findings.Our team developed a finite element modeling workflow to simulate implantation of braided stents in patient-specific aneurysm-artery model.An LVIS-based braided stent was deployed into an aneurysm-artery model.

The stent fully expanded, causing obvious deformation on the aneurysm-artery model.The workflow which we developed could provide reasonable deformed geometries Activity Toys of aneurysm-artery and braided stent for CFD computation and possibly assist surgical planning.
