Hi Sergey,

There are several method depending on your need. There are geometry-based approaches such as the work of Kim et al 2008 (Comparison of two stents in modifying cerebral aneurysm hemodynamics) where they used specific CAD software to deform the stent mesh or the study of Larrabide et al (Fast virtual deployment of self-expandable stents: method and in vitro evaluation for intracranial aneurysmal stenting) where a dedicated technique was developed. Besides, there are physics-based techniques such as the work of Peach et al. 2014 (Personalizing flow-diverter intervention for cerebral aneurysms: from computational hemodynamics to biochemical modeling).

If your goal is not to develop the technique but to use the stent mesh to do the CFD simulation, you can contact one of these authors (for example) and ask for the stent model (--> you create a collaboration). Send me a message and I can put you in contact with Dr Larrabide if you want.

Best regards,

Hernán

Hi Herman,

Tthank you very much for reply. Unfortunately I'm interesting in a developing a technique for stent modeling using CAD software. The problem is that I can not find any guide of how to deform a stent to fit a vessel. In all publication they present only a final stent geometry but there is now description of how to do it on practise.

With best regards,

Sergey
