Bioaktive proteser af ledende materiale belagt med en polymer og et stof med immunosuppressions-, antistenose- og antitromboseegenskaber

摘要

The invention relates to a bioactive implant comprising a substrate coated with a polymer layer with reactive functions, and a bioactive substance fixed on the implant by means of said reactive functions to enable progressive release on the implant site.Such implants are useful in the field of cardiology for example to prevent restenosis resulting from the fitting of stents in the coronary arteries.
