First Claim
Patent Images
1. An implantable device comprising a carbon coating and a bioactive agent attached thereto;
- wherein the bioactive agent is covalently attached to a photo-reactive chemical (PRC) which is in turn covalently attached directly to the carbon coating;
wherein the carbon coating comprises covalently linked carbon (C), hydrogen (H), silicon (Si), and oxygen (O) atoms; and
wherein the carbon coating comprises a diamond-like material.

Abstract
A carbon coating on a stent having a bioactive agent covalently attached thereto and methods of making the same are described. The covalent attachment may be achieved via a photo-reactive chemical or a thermo-reactive chemical. In some embodiments, the carbon coating includes a diamond-like material. The bioactive agent may be heparin or superoxide dismutase enzyme or a mimetic thereof.
