| abstract |
The invention provides an intraluminally-indwelling medical device such as a stent and a catheter, whose surface is uniformly and sufficiently coated with a medicament, and a concise and economical process thereof. The medical device is prepared by coating its surface with a mixture of plus-charged medical particles and biocompatible nanoparticles. The medicament is dissolved from the medical particles and the biocompatible nanoparticles after indwelling DES and then the medicament is efficiently taken in cells. |
