Abstract
Biocompatible nanoparticleswhich entrap a bioactive substance and whose surface is positive-charge-modified are electrically adhered to a balloon portionof a catheter main bodythrough a negatively charged resin layer, and thus a nanoparticle layeris formed. After the catheter main bodyis indwell in vivo, the nanoparticlesare gradually eluted from the nanoparticle layerand are effectively delivered to cells.
