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.

The present invention relates to antimicrobial compositions, methods for the production of these compositions, and use of these compositions with medical devices, such as catheters, and implants. The compositions of the present invention advantageously provide varying release kinetics for the active ions in the compositions due to the different water solubilities of the ions, allowing antimicrobial release profiles to be tailored for a given application and providing for sustained antimicrobial activity over time. More particularly, the invention relates to polymer compositions containing colloids comprised of salts of one or more oligodynamic metal, such as silver. The process of the invention includes mixing a solution of one or more oligodynamic metal salts with a polymer solution or dispersion and precipitating a colloid of the salts by addition of other salts to the solution which react with some or all of the first metal salts. The compositions can be incorporated into articles or can be employed as a coating on articles such as medical devices. Coatings may be on all or part of a surface.
