I'm working on a research for the university so i'm wondering does the artery return back the same if we didn't use a stent after inflate a balloon ? and why it's better to udse a stent that made from auxetic material? I know the properties for auxetic materials but what does it have to do with the blood?
Hi, Maryam.
stent is used for preventing artery elastic recoil, not avoiding it completely, but decreasing its impact on final result after balloon inflation.
So the initial loosing of diameter at the stenosis level after balloon inflation can be minimized by using stents. However, the first use of stents in PTCA was as a device for treating arterial wall dissection, and later was discovered that stenting helped to increase immediate final lumen diameter, and also decreasing the rate of restenosis.
i hope this coloquial comment would help you to better understanding of stents, best regards
