A stent graft () has a tubular body () defining a main lumen and a side tube () defining a side tube lumen and in fluid communication with the main lumen and defining a junction () between the tubular body and the side tube. The junction includes an acute angle of attachment (&#x3b1;). A first zig-zag stent () is wrapped around the tubular body such that a V portion of the first zig-zag stent is engaged about the acute angle of the junction and a second zig-zag stent () is wrapped around the side tube, such that a V portion of the second zig-zag stent is engaged about the acute angle of the junction, whereby the main lumen and the side tube are each kept open, independently, allowing fluid to flow freely therethrough.

Stented side branch graft

A stent graft has a tubular body of a biocompatible material and at least one fenestration. A tubular side branch is stitched into the fenestration with a portion of the side branch extending within the tubular body and a portion of the side branch extending exteriorly of the tubular body. The stitching by which the side branch is mounted into the fenestration extends circumferentially and diagonally from one end of the side branch to the other such that the side branch extends from the tubular body at an angle thereto. The tubular side branch may have a reinforcement stent having at least one helical wire segment.

Side branch stent graft construction

A stent graft () has a tubular body () of a biocompatible material and at least one fenestration (). The or each fenestration has a tubular side branch stitched into it with a portion of the tubular side branch extending within the tubular body and a portion of the tubular side branch extending exteriorly of the tubular body. The stitching by which the tubular side branch is mounted into the fenestration extends circumferentially and diagonally from one end of the tubular side branch to the other such that the tubular side branch extends from the tubular body at an angle thereto. The tubular side branch has a resilient ring around at least one and preferably both ends thereof and a self expanding stent in between them. The tubular side branch can have a circumferential linear portion () at an inner end to engage against the inner wall () of the tubular body. The tubular side branch can have a stent made from a single wire forming a first ring (), a second ring (), the second ring defining a plane which is substantially parallel to and spaced axially apart from the plane of the first ring and a number of helical wire portions () extending between the first and second ring. Preferably the wire is a shape memory wire such as Nitinol&#x2122; wire.
