DRUG-ELUTING CATHETER AND METHOD OF MANUFACTURING THE SAME |
| 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.
