STENT
Document Type and Number:
WIPO Patent Application WO/2015/174590
Kind Code:
A1
Abstract:
The present invention relates to a stent comprising: a stent body, in a tube form, which has metal wires intersect so as to form a net in a lattice or a mesh form and which has a hollow inside thereof; and a coating film which is formed by covering the surface of the stent body, wherein the coating film can be formed as a coating solution in which a silicone polymer, provided in a solution form, and hydrophobic polymer particles, having lower coefficient of friction than the silicone polymer, are stirred. The present invention has the advantages of: by means of a coating film having low frictional force, preventing material that passes through a lesion site from being deposited on the surface of a stent; the coating film of the stent preventing lesion cites of a bile duct or a blood vessel from coming in direct contact with material that passes through the stent; by having a contact surface of the coating film formed on the stent support the inner walls of the bile duct and the blood vessel, preventing restenosis of the bile duct and the blood vessel generated due to the proliferation of neointima inside the stent; and being applied to various lesion cites by having wear resistance and flexibility of the existing silicone coated stent maintained as much as possible.
