Abstract

The present disclosure relates to an endoluminal prosthesis, such as a stent graft that includes one or more fenestrations to accommodate endovascular disease, such as an aneurysm in cases where one or more side branches is involved. In one aspect, the prosthesis includes fenestrations that are pivotable to accommodate the dynamic geometry of the aortic branches. In another aspect, the pivotable fenestrations include a first perimeter, a band of flexible material attached and surrounding the first perimeter, and a second perimeter attached to and surrounding the band of flexible material. The first perimeter, band of flexible material, and second perimeter have a geometric shape. In one aspect, the prosthesis includes at least three pivotable fenestrations.

Claims20

Dependent claims

An endoluminal prosthesis, comprising:

a graft having a tubular body and a surface comprising a first biocompatible material;
a stent frame having a plurality of stent units attached to the graft about the surface of the graft and arranged in longitudinally spaced rows, at least one of the stent units comprising a plurality of struts interconnected by apices;
at least three fenestrations disposed through a sidewall of the graft, each fenestration having a diameter;
a first perimeter having a first diameter and surrounding each of the fenestrations;
each first perimeter having a band of flexible material attached to and surrounding the perimeter, the band of flexible material having a depth relative to a surface plane of the tubular body;
and
each band of flexible material having a second perimeter attached to and surrounding the band of flexible material;
where the first perimeters, the bands of flexible material, and the second perimeters have a geometric shape and where each fenestration is pivotable in any direction away from an axis perpendicular to a longitudinal axis of the prosthesis, where at least two of the fenestrations are positioned on opposing sides of the graft, and
where the at least three fenestrations extend from an internal surface of the graft to the external surface of the graft.
