Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 94 words
An articulated stent, comprising: (a) at least two substantially rigid segments having a plurality of connected cells each having apices, wherein, upon expansion, each of said rigid segments presents a substantially cylindrical diamond mesh; and (b) a flexible connector, comprising a plurality of flexible links wherein each of said flexible links connects apices of adjacent cells on adjacent rigid segments; each of said flexible links includes a plurality of portion with each pair of neighboring portions having an area of inflection therebetween, and during expansion of said stent, said area of inflection remains inflected.
Claim 2
Dependent Claim 94 words
An articulated stent, comprising: (a) at least two substantially rigid segments having a plurality of connected cells each having apices, wherein, upon expansion, each of said rigid segments presents a substantially cylindrical diamond mesh; and (b) a flexible connector, comprising a plurality of flexible links wherein each of said flexible links connects apices of adjacent cells on adjacent rigid segments; each of said flexible links includes a plurality of portion with each pair of neighboring portions having an area of inflection therebetween, and during expansion of said stent, said area of inflection remains inflected.
