1. An endoluminal device, comprising:
- a stent;
a tubular graft supported by the stent, wherein the graft comprises at least a proximal opening and a distal opening; and
a variable diameter ring at or adjacent at least one of said openings, wherein the variable diameter ring comprises a coiled length of wire having two ends and forming substantially at least one winding around the tubular graft, wherein the coiled length of wire has a head end and a tail end, the head end having a loop through which the tail end of the wire passes.

Abstract
This invention is an endoluminal device including a stent; a tubular graft supported by the stent, wherein the graft comprises a proximal opening and a distal opening; and a variable diameter ring adjacent one of said openings, wherein the variable diameter ring comprises a coiled length of wire having two ends and forming at least one winding around the tubular graft. This invention also relates to the methods of treating an aneurysm and making the endoluminal device.

17. An endoluminal device comprising:
-
a stent; a branched tubular graft supported by the stent, wherein the graft comprises at least a proximal opening and two distal openings; and a variable diameter ring at or adjacent at least one of said openings, wherein the variable diameter ring comprises a coiled length of wire having two ends and forming substantially at least one winding around the tubular graft, wherein the coiled length of wire has a head end and a tail end, the head end having a loop through which the tail end of the wire passes.

18. An endoluminal device, comprising:
-
a stent; a tubular graft supported by the stent, wherein the graft comprises at least a proximal opening and a distal opening, the endoluminal device having a compressed state and an expanded state; and a variable diameter ring at or adjacent at least one of said openings, wherein the variable diameter ring comprises a coiled length of wire having two ends and forming substantially at least one winding around the tubular graft in the expanded state, wherein the coiled length of wire has a head end and a tail end, the head end having a loop through which the tail end of the wire passes, wherein an initial number of windings of the variable diameter ring in the compressed state is a product of an expansion ratio and a number of windings in the expanded state; wherein the expansion ratio is a ratio of an expanded stent graft diameter by a compressed stent graft diameter; and wherein a length of wire is equal to a result of multiplying the number of initial wire windings by Pi (π
) and by the expanded stent graft diameter.
