An intravascular stent having a prefabricated, patterned polymeric sleeve
for controlled release of therapeutic drugs and for delivery of the
therapeutic drugs in localized drug therapy in a blood vessel is
disclosed. The polymeric sleeve is attached to at least a portion of an
outside surface area of the stent structure. Alternatively, a plurality
of individual microfilament strands are longitudinally attached to an
outer surface of a stent structure in a spaced apart orientation and
loaded with at least one therapeutic drug for the release thereof at a
treatment site. The stent has a high degree of flexibility in the
longitudinal direction, yet has adequate vessel wall coverage and radial
strength sufficient to hold open an artery or other body lumen. Methods
for making the same are also disclosed.
