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.
Claims20
A prosthesis, comprising:
- a graft having a tubular body and a surface comprising a first biocompatible material;
- at least one fenestration having a diameter extending from a sidewall of the graft;
- a first perimeter having a first diameter and surrounding the fenestration;
- a band of flexible material attached to and surrounding the first perimeter and having a flexible frame;
- a second perimeter attached to and surrounding the band of flexible material and having a second diameter greater than the first perimeter diameter;
- where the band of material has a first diameter substantially the same as the first perimeter diameter and a second diameter substantially the same as the diameter of the second perimeter, and where the diameter of the band of material decreases in a direction away from the surface of the graft from the second perimeter to the first perimeter;
- and
- where each fenestration is pivotable in any direction away from an axis perpendicular to a longitudinal axis of the prosthesis.
The prosthesis of claim 5, wherein the first perimeter, the band of material, and the second perimeter form a hemispherical shape and are substantially concentric when positioned in the same plane.
A prosthesis for treatment of a main vessel defect near one or more branch vessels, comprising:
- a tubular graft body having a surface comprising a biocompatible material;
- at least one fenestration having a diameter disposed extending from a sidewall of the graft;
- a first perimeter having a first diameter and surrounding the fenestration;
- a band of material attached to and surrounding the first perimeter and having a flexible frame;
- a second perimeter having a second diameter greater than the first perimeter diameter attached to and surrounding the band of material;
- where each fenestration is pivotable in any direction away from an axis perpendicular to a longitudinal axis of the prosthesis.
A prosthesis for treatment of a main vessel defect near one or more branch vessels, comprising:
- a tubular graft body;
- at least one fenestration having a diameter disposed extending from a sidewall of the graft and a surrounding perimeter;
- a band of flexible material attached to and surrounding the perimeter of the at least fenestration and having a flexible frame;
- where each fenestration is pivotable in any direction away from an axis perpendicular to a longitudinal axis of the prosthesis.
