Intracranial aneurysms are a life-threatening disease, which can be treated with flow diverter stents. However, complications during or after this endovascular treatment might occur. Therefore, there is a need to improve the current minimally-invasive technologies. In the present study, we proposed and utilized the concept of the iterative stent design focusing on 1) fast prototyping using microsystem technologies and 2) in vitro testing the flow reduction in real-world conditions using 4D flow MRI. As a result, the flow volume entering the aneurysm in the presence of a stent was reduced by 10 %, and then by 85 %.
