Abstract
A method for delivering heparin, wherein an implantable stent is coated with a material that attracts heparin and with which heparin forms a bond. The stent is exposed to a heparin containing solution just prior to implantation or is first implanted and then exposed to heparinized blood. As heparin becomes detached from the stent, the implantation site is exposed to heparin to restore an effective level and thereby prevent thrombosis.
