Abstract
Stent grafting is one of the treatments for thoracic aortic aneurysm that is less invasive than open surgery. However, it sometimes involves in serious problems: Endoleak and Migration. These problems seem to have a relation to the oversize of stent or wrong position of stent on the arterial wall, and so the evaluation of the problems should be performed quantitatively using in-vitro model with observation of sealing. The purpose of this research is the development of in vitro model made of PVA-H (Poly Vinyl Alcohol Hydrogel) for evaluation of endoleak and migration on stent graft. We used Dip-Coating method to make the model. Dip-Coating is the method which forms a liquid film on the surface of the mold (Nylon12) by dipping the mold in PVA-H. As the result, the method using Nylon12 as a material of the mold enables to make the model with a similar surface roughness to the conventional method. In addition, the model has a high transparency and will be used for PIV.
