843 Mechanical characteristic evaluation of polymer stent with hoop structure
Details
It is a problem that metal stent can't be used to treat young people medically because it stays permanently in body. And it also cause artifact in MRI imaging. So we have developed polymer stent with hoop structure that can be produced with polymer film. In this research, we evaluated radial force of stent as mechanical characteristics. We fabricated and examined stents made of polyethylene terephthalate (PET) and biodegradable polymer, poly L-Lactide (PLA). The experimental results show that PET and PLA stents have larger radial force than that of a type of metal stent.
