A hybrid stent is formed which exhibits both high flexibility and high
radial strength. The expandable hybrid stent for implantation in a body
lumen, such as a coronary artery, consists of radially expandable
cylindrical rings generally aligned on a common longitudinal axis and
interconnected by one or more links. In one embodiment, a dip-coated
covered stent is formed by encapsulating cylindrical rings within a
polymer material. In other embodiments, at least some of the rings and
links are formed of a polymer material which provides longitudinal and
flexural flexibility to the stent. These polymer rings and links are
alternated with metallic rings and links in various configurations to
attain sufficient column strength along with the requisite flexibility in
holding open the target site within the body lumen. Alternatively, a
laminated, linkless hybrid stent is formed by encapsulating cylindrical
rings within a polymer tube.
