    Abstract: The present invention is directed to a flexible expandable stent for implantation in a body lumen, such as a coronary artery. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of links which be polymeric or metallic. Varying configurations and patterns of the links provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis. The metallic material forming the rings provides the necessary radial stiffness.

    Abstract: An implantable prosthesis, for example a stent, is provided having one or more elements that form the body structure of the prosthesis. The elements have a width that is variable from a nominal or conventional width to an increased width. Depots are formed in the elements and are generally located at the increased width portions of the elements. The diameter of the depots is based on a percentage of the width of the element. As such, the depots have increased drug-loading capabilities. Substances such as therapeutic substances, polymeric materials, polymeric materials containing therapeutic substances, radioactive isotopes, and radiopaque materials can be deposited into the depots. Further, the variable width of the elements ensures that sufficient material surrounds each depot so as not to compromise the structural integrity of the prosthesis.
