| Fluid mechanics is critically involved in the design of vascular grafts
and intravascular stents. The failure of these devices is often related
to their poor hemodynamic performance, which is due to improper geometric
designs. CFDRC has developed the technology which is widely used to facilitate
the rapid development of grafts, stents and filters. For example, the fluid-structure
interaction capabilities have been used to study the stress distributions
in the arterial and graft walls at the proximal end of an end-to-end anastomosis.
In another example, the CFDRC Filament model is employed to simulate the
performance of a clot filter inserted into a blood vessel. |
