STENT

摘要

The present invention relates to a stent comprising: a hollow tube-shaped stent body in which multiple metal wires having a plurality of curves are cross-linked to each other; and a coating film formed so as to cover the surface of the stent body, wherein silver (Ag) particles for inhibiting bacterial growth in a lesion region may be added in the coating film. According to the present invention, the silver particles contained in the coating film have an anti-bacterial effect which prevents the growth of bacteria in a lesion region, the coating film of the stent prevents a direct contact between a lesion region in the biliary tract and a blood vessel and substances passing through the stent, and the contact surface of the coating film formed on the stent supports the inner wall of the biliary tract and the blood vessel, thereby preventing in-stent restenosis of the biliary tract and the blood vessel, which is caused by neointima penetrating into the stent.
