Abstract

Attaining high hemocompatibility and promoting endothelialization are two major keys to solve the endoleak problems observed in existing stent-grafts. For the satisfactory long-term use of the stent-grafts, blocking the endoleak symptom is highly essential. This paper deals with the fabrication of electrospun nanofibers made of antithrombogenic poly(2-methacryloyloxyethyl phosphorylcholine) (MPC) containing drug that can sustain the endothelial activity of the MPC nanofibers. Moreover, the drug release was controlled by micro-patterned diamond-like carbon (DLC) coated on the MPC nanofibers. It was found that MPC nanofibers retained excellent hemocompatibility and that the micro-patterned DLC efficiently controlled the drug-release rate of MPC fibers.
