An intravascular stent having a prefabricated, patterned tubular sleeve
portion for controlled release of therapeutic drugs and for delivery of
the therapeutic drugs in localized drug therapy in a blood vessel is
disclosed. The patterned sleeve may be releasably attached to at least a
portion of an outer surface of the stent structure. Alternatively, a
plurality of individual filament strands are longitudinally arranged
around 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.
