AbstractA Swiss company with strong experience in 3D fluid flow modeling, including pressure and shear stress distributions, as well as fluid/structure interaction, is interested in collaborating with implant and medical device manufacturers or research institutes for testing new applications. Design optimization of stents, valves, pumps or novel drug delivery systems are among the targeted applications.DetailsA Swiss company, with over ten years experience in numerical simulations for various applications such as aeronautics, heat transfer and chemically reacting flows is expanding its activities in the medical field.Problems relating to biofluid mechanics in humans are varied: flow relating to blood in the heart, air flow in the human nose, lungs, and ears, etc. Numerical simulations, and in particular Computational Fluid Dynamics (CFD), can be used for the development and the improvement of medical devices or the assessment of surgery techniques. Namely, the simulation of medical devices (stents, valves, pumps or drug delivery systems) and their interaction with the surrounding fluids can establish system performance and identify critical parameters. The long time experience of the company in fluid mechanics as well as the ability to modify the in-house code to meet individual client needs is a major advantage. The company can model 2D or fully 3D geometries and solve fluid flows using its completely parallelized in-house code (NSMB) based on a multiblock approach and a finite volume discretization. Expertise in fluid/structure interaction modelling is also offered, which is particularly important for biological systems. CFD has been applied to study the flow patterns in blood vessels, in conjunction with pressure and shear stress distributions, providing an important tool for the evaluation of the potential rupture of an aneurysm. CFD has also been used successfully for improving bovine cardiac valve implantation techniques by modeling valve/blood interaction, leading to design and surgical technique (valves positioning) improvement. The company is looking for collaboration with research institutes, university hospital, companies, developers or manufacturers of biomedical devices or, wishing to test novel surgical techniques, medical devices, or to better understand fluid behaviour in humans, using non-invasive fluid mechanical approaches. Innovative Aspects: - flow patterns, in conjunction with pressure and shear stress distributions - modeling fluid/structure interaction, - non-invasive trial-and-error technique for testing surgical procedures where blood or respiratory flows are critical. - the use of CFD modeling tools substantially reduces the time and cost of the design and development of biomedical devices where any kind of liquid or gas flows occur.
