Abstract
A multiple-component expandable endoluminal system for treating a lesion at a bifurcation including a self expandable tubular root member having a side-looking engagement aperture, a self expandable tubular trunk member comprising a substantially blood impervious polymeric liner secured therealong; both having a radially compressed state adapted for percutaneous intraluminal delivery and a radially expanded state adapted for endoluminal support.
Claims26
A stent graft system comprising:
- a first component, which comprises a tubular structure, which comprises a first support element and a first covering element attached to said first support element, two sides of said first component being positionable, respectively, in first and second branches that branch from a main trunk of a subject, wherein said first covering element is shaped so as to define an opening arranged to face said main trunk;
- and
- a second component, which comprises a second support element and a second covering element attached to said second support element, said second component configured to be at least partially disposed within said first component, extending outwardly from said opening,
- wherein said second component comprises a proximal segment and a distal segment, said proximal segment being dimensioned to be anchorably disposable within one of said sides of said first component, such that said distal segment of said second component outwardly extends from said opening, and
- wherein said second covering element only partially covers said second support element so as to allow blood flow to both of said sides of said first component.

A method comprising:
- implanting, respectively in first and second branches that branch from a main trunk of a subject, two sides of a first component of a stent graft system, which first component includes a first support element and a first covering element attached to said first support element, such that an opening defined by said first covering is aligned to face said main trunk;
- and
- implanting a second component of said system partially in said main trunk, which second component includes a second support element and a second covering attached to said second support element, by disposing at least a distal portion of said second component within said main trunk, and anchoring at least a proximal portion of said second component within one of said sides of said first component,
- wherein said second covering element only partially covers said second support element so as to allow blood flow to both of said sides of said first component.
