The invention discloses a coronary rapamycin targeted
elution stent which is thin in wall, small in occupied space, good in
blood vessel trafficability, small in interference on
blood flow, beneficial to maintaining
normal blood flow, high in supporting force and pushing force, more flexible in the conveying process and capable of passing through tortuous and narrow coronary
artery diseased regions more easily. The
stent body can be well attached to the
blood vessel wall, the gap between the
stent body and the
blood vessel wall is reduced, growth and covering of vascular endothelial cells are facilitated, and the risk of
thrombosis and
restenosis is reduced; the connecting piece is
omega-shaped, so that the bracket main body can form enough radial strength; the
polymer coating coated on the surface of the stent main body not only can finish precise sustained release of a
drug, but also can realize complete degradation, and the
polymer coating can promote growth and repair of vascular endothelial cells, accelerate the vascular endothelialization process, and is beneficial to
recovery of normal physiological functions of blood vessels, so that the stent has a good application prospect. And the risk of
thrombosis and
restenosis is reduced.
