摘要： Biocompatible nanoparticles 1 which entrap a bioactive substance and whose surface is positive-charge-modified are electrically adhered to a balloon portion 9 of a catheter main body 5 through a negatively charged resin layer 11, and thus a nanoparticle layer 12 is formed. After the catheter main body 5 is indwell in vivo, the nanoparticles 1 are gradually eluted from the nanoparticle layer 12 and are effectively delivered to cells.

摘要： The present invention provides a medical device for placement into a lumen such as a stent and a catheter whose surface is uniformly and sufficiently coated with a drug, and a process thereof with easy way and with low cost. The medical device is coated with mixed particles of drug particles whose surface is modified with positive-charge and biocompatible nanoparticles. In the invention, a drug can be taken into a cell through the dissolution of the drug particle together with the biocompatible nanoparticle after a DES is placed in a biological body.
