Abstract:
Vascular or endoluminal stent is a stent implanted in the lesion site to support stenosis vessels based on luminal balloon expansion,to reduce vascular elasticity recoil and remoulding,and maintain blood flow patent.Some stents can also prevent vascular restenosis.Stent size,surface coverage,radial supporting,extensibility,longitudinal recoil,fatigue test,material composition,corrosion-resistance,coagulation,surface roughness and biocompatibility(blood compatibility) are performance parameters to evaluate the stents.Vascular or endoluminal stent has been widely used in arterial and venous systems and non-vessel luminal systems.The incidence of complications following stenting is 11.6%,including acute or subacute thrombogenesis,restenosis,or stent dislocation.It is commonly demonstrated that intrastent restenosis is caused by hyperblastosis.
