Abstract

A generally tubular intraluminal compound stent comprising a plurality of component stents, each component stent having a length and a plurality of individual hoops axially disposed along the length and connected by a connecting spine, the component stents meshed with one another such that at least one hoop of one component stent is positioned between axially adjacent hoops of another component stent. The connecting spines may be helical, with at least one component stent spine oriented in a different helical direction than the spine of another component stent. Each hoop may further have a periphery comprising a pattern of zig-zags having apices, wherein adjacent hoops of the meshed component stents are aligned such that the apices of adjoining hoops abut or are interdigitated with one another. The compound stent may further comprise connectors, such as sutures, connecting at least some of the abutting or interdigitated apices. A process for manufacture of a flexible endoluminal compound stent is also disclosed.
