The present invention provides a drug-coated stent comprising a tubular flexible body having a wall with a web structure that is expandable from a contracted delivery configuration to deployed configuration. The web structure comprises a plurality of neighboring web patterns, where each web patterns is composed of adjoining webs, and the web patterns are interconnected by transition sections. Each adjoining web comprises a central section interposed between two lateral sections to form concave or convex configurations.

What is claimed is: 1. A stent for supporting a vessel comprising: a tubular body having a longitudinal axis, and having proximal and distal ends and a lumen extending longitudinally therebetween, and a wall having areas thereof that define a web structure configured for circumferential expansion from a contracted delivery configuration to an expanded deployed configuration; the web structure comprising a plurality of web patterns that are interconnected with one another at a plurality of interconnection locations, and arranged so that the web patterns are situated side-by-side along the longitudinal length of the tubular body, with each web pattern also extending circumferentially around the wall; at least one of said interconnected web patterns comprising, at least three webs joined end-to-end so as to extend between a pair of H-shaped transition sections with no other H-shaped transition sections between the pair of H-shaped transition sections; said three webs that are joined end-to-end being joined by two bends so that the bends permit the three webs to be generally foldable between the pair of H-shaped transition sections when said tubular body is in the contracted delivery configuration, and then unfolded when said tubular body is expanded to the deployed configuration; and said at least three webs each comprising a plurality of web sections, with one of the web sections being angled relative to one other web section when the stent is in the expanded deployed configuration. 2. The stent of claim 1, wherein at least one of the H-shaped transition sections is disposed at an angle relative to the longitudinal axis of the tubular body. 3. The stent of claim 1, wherein each web comprises three web sections, with one of the sections being a central section joined at opposite ends thereof to two lateral sections, with at least one of the three web sections comprising a substantially straight section. 4. The stent of claim 1, wherein each web comprises three substantially straight sections, and wherein each of the lateral sections is angled relative to the central section when the stent is expanded, with each angle being expandable when the webs are unfolded to place the stent in the expanded deployed configuration. 5. The stent of claim 1, wherein each of the H-shaped transition sections interconnects a web pattern, and wherein said at least three webs joined end-to-end defines an S-shaped structure. 6. The stent of claim 1, wherein the tubular body is formed using a material so that the stent is balloon expandable when deployed. 7. The stent of claim 1, wherein the tubular body comprises a deformable material. 8. A stent comprising: a tubular body having a longitudinal axis, and having proximal and distal ends and a lumen extending longitudinally therebetween, and a wall having areas thereof that define a web structure configured for circumferential expansion from a contracted delivery configuration to an expanded deployed configuration; the web structure comprising a plurality of web patterns that are interconnected with one another at a plurality of interconnection locations, and arranged so that the web patterns are situated side-by-side along the longitudinal length of the tubular body, with each web pattern also extending circumferentially around the wall; at least one of said interconnected web patterns comprising, at least three webs joined end-to-end so as to extend between a pair of H-shaped transition sections, with no intervening H-shaped transition sections between the pair of H-shaped transition sections; said three webs that are joined end-to-end being joined by two bends so that the bends permit the three webs to be generally foldable between the pair of H-shaped transition sections when said tubular body is in the contracted delivery configuration, and then unfolded when said tubular body is expanded to the deployed configuration; and each web comprising three web sections, with one of the web sections being a central section joined at opposite ends thereof to two lateral sections, each of the lateral sections being angled relative to the central section when the stent is in the expanded deployed configuration. 9. The stent of claim 8, wherein at least one of the H-shaped structures is disposed at an angle relative to the longitudinal axis of the tubular body. 10. The stent of claim 8, wherein at least one of the three web sections comprises a substantially straight section. 11. The stent of claim 10, wherein each web comprises three substantially straight sections, and wherein each of the lateral sections is angled relative to the central section when the stent is expanded, with each angle being expandable when the webs are unfolded to place the stent in the expanded deployed configuration. 12. The stent of claim 8, wherein the at least three webs are joined end-to-end in a manner that defines an S-shaped structure between the two and only two H-shaped transition sections. 13. The stent of claim 8, wherein the stent is formed using a material so that the stent is balloon expandable when deployed. 14. The stent of claim 8, wherein the stent comprises a deformable material.
