The effect of stents structural parameters to flow in stented aneurysms

Investigation on the changes of flow patterns in a blood vessel with a fixed fusiform aneurysm resulting from placement of a different structural void area of stents. The velocity profile and pressure distribution after installing the device had been identified from the selected stent. Three differe...
