A stent is formed by encasing or encapsulating metallic rings in an inner
polymeric layer and an outer polymeric layer. At least one polymer link
connects adjacent metallic rings. The stent is drug loaded with one or
more therapeutic agent or drug, for example, to reduce the likelihood of
the development of restenosis in the coronary arteries. The inner and
outer polymeric materials can be of the same polymer or different polymer
to achieve different results, such as enhancing flexibility and providing
a stent that is visible under MRI, computer tomography and x-ray
fluoroscopy.
