Traditional commercial stents are made of wires with square or semi‐circular cross‐sections that lead to flow disturbance, which plays an important role in the initiation and progression of restenosis. A new stent with streamlined cross‐sectional wires was proposed and researched numerically for its hemodynamic performance. Simplified models of stents with square, semi‐circular, or streamlined cross‐sectional...
The development of distal end-to-side anastomotic intimal hyperplasia (IH) has been attributed to the flow disturbance and abnormal wall shear stress (WSS) distribution there. The geometry of the bypass has a strong influence on the flow pattern and WSS distribution. Using a canine model of end-to-side anastomosis, a 45° S-type bypass was compared with 60°, 45° and 30° conventional bypasses in the...
