Abstract
Abstract An articulated stent for delivering through a bodily conduit, for example, a peripheral or coronary artery, which has one or more curved portions and for implantation therein. The articulated stent includes at least two substantially rigid segments and a flexible connector for connecting adjacent segments. The connector assumes a cylindrical configuration when relaxed and a differentially stretched and compressed curved configuration when flexed.

Claim 2
Dependent Claim
52 words
A connector for connecting adjacent areas of adjacent substantially tubular and substantially rigid segments of an articulated stent, the connector comprising: a plurality of flexible links, wherein each of said flexible links includes a plurality of portions with each pair of neighboring portions when viewed laterally having an area of inflection therebetween.
Claim 3
Dependent Claim
23 words
