DRUG ELUTING STENT WITH A BIODEGRADABLE RELEASE LAYER ATTACHED WITH AN ELECTRO-GRAFTED PRIMER COATING

摘要

A drug eluting preventing restenosis, avoiding thrombosis and allowing for early proliferation and migration of endothelial cells is disclosed. The stent has a surface with a layer that promotes proliferation and adhesion of the endothelial cells and a drug hosting biodegradable polymer coating covering the surface which is degraded to completely release the drug.
