Abstract
(EN)
The present invention relates to a medical implant, and more particularly, to a vascular implant having a dual coating structure for preventing in-stent restenosis and thrombosis. In one embodiment, the invention contemplates a vascular stent with a coating comprising a hydrophobic, degradable core with a coaxial sheath comprising at least one polyethylene-glycol derivative. In one embodiment, said at least one polyethylene-glycol derivative comprises polyethylene-glycol dimethacrylate.
