A stent having a multi-layered coating adhered to its surface which can
prevent restenosis and thrombosis at the implant site. The stent coating
is comprised of two layers. The first layer is a polymeric coating with
one or more biologically active agent(s) dispersed therein. The second
layer is comprised of a hydrophobic heparinized polymer that inhibits
blood coagulation and provides a hydrophilic surface for reducing the
friction between stent and lesion site. In preferred embodiments of the
invention, the multi-layered stent is effective in deterring restenosis
and thrombosis at the implant site. In these same preferred embodiments,
the multi-layered stent is capable of reducing the burst release of the
biologically active agents from the first layer and sustaining a release
of an effective amount of these agents for a relatively extended period
of time. Methods of applying the multi-layered coating to the stent
surface are also part of this invention.
