Abstract
The present invention provides a 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. Each adjoining web comprises a central section interposed between two lateral sections to form concave or convex configurations.

A stent comprising:
- a tubular body with a wall having a web structure configured to expand from a contracted delivery configuration to an expanded deployed configuration,
- the web structure comprising a plurality of interconnected, neighboring web patterns, each web pattern having a plurality of adjoining webs, each adjoining web comprising a central section interposed between first and second lateral sections,
- wherein the central section is substantially parallel to a longitudinal axis of the stent when in a contracted delivery configuration, each of the first lateral sections joins the central section at a first angle, each of the second lateral sections joins the central section at a second angle, and adjacent ones of the neighboring web patterns having alternating concavity.
A method for stenting at a target site within a patient's vessel comprising:
- providing a stent comprising a tubular body with a wall having a web structure, the web structure comprising a plurality of interconnected, neighboring web patterns, each web pattern having a plurality of adjoining webs, each adjoining web comprising a central sections interposed between two lateral sections, wherein the central section is substantially parallel to a longitudinal axis of the stent when in a contracted delivery configuration, and adjacent ones of the neighboring web patterns having alternating concavity;
- percutaneously delivering the stent to the target site within the patient's vessel in a contracted delivery configuration;
- and
- deploying the stent to an expanded deployed configuration, wherein the stent engages the target site.
