Abstract
The present embodiments provide a stent graft having a tubular configuration defining a lumen therethrough, the stent graft having a proximal section and a distal section. A folded section is positioned between the proximal section and the distal section. The folded section includes a first fold directed toward the distal end and engaged with the proximal section and a second fold directed toward the proximal end and engaged with the distal section. A valve arrangement is positioned in at least one of the first and second folds providing access from an exterior of the graft to the interior of the stent graft for insertion of an additional device.

An endoluminal prosthesis comprising:
- a graft having a tubular configuration defining a lumen therethrough, the graft having a proximal end, a distal end, a proximal section and a distal section;
- a folded section positioned between the proximal section and the distal section, the folded section having a first fold directed toward the distal end and engaged with the proximal section and a second fold directed toward the proximal end and engaged with the distal section;
- and
- a valve arrangement positioned in at least one of the first and second folds.
An endoluminal prosthesis assembly comprising:
- a graft comprising a main graft body having a tubular configuration defining a lumen therethrough;
- at least one leg section attached distal to the main graft body and having a lumen in fluid communication with the main lumen;
- the leg section having a proximal section and a distal section;
- a folded section positioned between the proximal section and the distal section of the leg section, the folded section having a first fold directed toward the distal end and engaged with the proximal section and a second fold directed toward the proximal end and engaged with the distal section;
- and
- a valve arrangement positioned in at least one of the first and second folds.
An endoluminal prosthesis comprising:
- a graft having a tubular configuration defining a lumen therethrough, the graft having a proximal section and a distal section;
- a plurality of stents attached about an outer surface of the graft, the stents having a generally undulating configuration;
- and
- a slit valve arrangement disposed through an outer surface of the graft.
