The objective of this study is to present a credibility assessment finite element modelling self-expanding nickel-titanium (Ni-Ti) stents through verification and validation (VV) activities, as set out in the ASME VV-40 standard. As part study, role calculation verification, model input sensitivity, examined across three different application contexts (radial compression, stent deployment vessel, fatigue estimation). A commercially available Ni-Ti was modelled, activities addressed effects...
Abstract Purpose Altered hemodynamics caused by the presence of an endovascular device may undermine success peripheral stenting procedures. Flow-enhanced stent designs are under investigation to recover physiological blood flow patterns in treated artery and reduce long-term complications. However, flow-enhanced require development customised manufacturing processes that consider complex behaviour Nickel-Titanium (Ni-Ti). While routes traditional self-expanding Ni–Ti stents...
Despite being commonly employed to treat peripheral artery disease, self-expanding Nitinol stents are still associated with relatively high incidence of failure in the mid- and long-term due in-stent restenosis or fatigue fracture. The practise stent oversizing is necessary obtain suitable lumen gain apposition vessel wall, though it regarded as a potential cause negative clinical outcomes when mis-sizing occurs. objective this study was develop computational model provide better...
Abstract Self-expanding Nitinol stents are the preferred treatment for atherosclerotic diseases in femoral arteries. However, adverse clinical outcomes recorded and mostly attributed to altered flow dynamics caused by device, which can lead in-stent restenosis 15% 32% of stented segments within 9 15 months post-intervention. Spiral laminar (SLF) technology consists a helical ridge on inner surface recovers natural blood downstream reduces disturbance turbulence stenting, thus preventing...
