Abstract
The invention relates to a stent for implantation in a body lumen. The stent is formed from stent preforms. Each stent preform includes an elongated metal core, an outer sheath disposed about the core, and caps disposed on the ends of the outer sheath. The outer sheath and caps encapsulate the metal core to prevent the core from directly contacting the body lumen. In an alternative embodiment, an intermediate sleeve is disposed between the core and outer sheath. In another embodiment, a cover or coating may be disposed about the outer sheath.
