Abstract:
Stenting of curved arteries is generally perceived to be more challenging
than straight vessels. Conceptually implanting multiple
shorter stents rather than a single longer stent into such a curved
artery represents a promising concept, but little is known about
the impact of such an approach. The objective of this study is to
evaluate the effectiveness of using a multiple segment stent rather
than a single long stent to dilate a curved artery using the finite
element method. A double segment stent (DSS) and a single segment
stent (SSS) were modeled. The stents were compared when
expanded into a model of a curved artery. The model predicts that
the DSS provides higher flexibility, more conformity, and lower
recoil in comparison to the SSS. The volume of arterial tissue
experiencing high levels of stress due to stent implantation is also
reduced for the DSS. It is suggested that a multiple segment stenting
system is a potential solution to the problem of higher rates of
in-stent restenosis in curved arteries and mechanically challenging
environments.
