This invention provides compositions and methods for producing a medical
device coated with a matrix and an antibody which reacts with an
endothelial cell antigen. The matrix coating the medical device may be
composed of synthetic material, such as polyurethane, poly-L-lactic acid,
cellulose ester or polyethylene glycol. In another embodiment, the matrix
is composed of naturally occurring materials, such as collagen, fibrin,
elastin, amorphous carbon. In a third embodiment, the matrix may be
composed of fillerenes. The fullerenes range from about C60 to about
C100. The medical device may be a stent or a synthetic graft. The
antibodies promote adherence of eadothelial cells on the medical device.
The antibodies may be mixed with the matrix or covalently tethered
through a linker molecule to the matrix. Following adherence to the
medical device, the endothelial cells differentiate and proliferate on
the medical device. The antibodies may be different types of monoclonal
antibodies. Methods of preparing such composition and methods of treating
a mammal with atherosclerosis or other types of vessel obstruction are
disclosed. By facilitating adherence of endothelial cells to the surface
of the medical device, the methods and compositions of this invention
will decrease the incidence of restenosis as well as other thromboembolic
complications resulting from implantation of medical devices.
