VASCULAR STENT HAVING A DUAL COATING STRUCTURE

摘要

Disclosed is a vascular stent which is inserted inside a blood vessel. The disclosed vascular stent comprises: a first coating film comprising a restenosis inhibiting drug provided on the outside surface of the stent strut; and a second coating film comprising an internal-capsule cellularization promoting drug provided on the inside surface of the stent strut. In this way, restenosis and thrombosis can be prevented from occurring inside the stent.
