Provided is a medical device for placement into a lumen and a simple and inexpensive manufacturing method thereof, said medical device being a stent or a catheter and the surface thereof being uniformly and sufficiently coated with a drug. Drug particles having positive-charge modified surfaces and biocompatible nanoparticles are mixed and stuck to the medical device. After the DES is placed inside a living organism, the drug particles are eluted together with the biocompatible nanoparticles and efficiently taken into cells. |
