A stent graft () for placement in the thoracic arch of a patient has a first tubular body portion () with a first lumen therein for placement in the ascending aorta of a patient and a second tubular body portion () to extend along the thoracic arch and down the descending aorta. The second tubular body portion is of a lesser diameter than the first tubular body portion. There is a step portion () between the first body portion and the second body portion. The step portion is joined to and continuous with the first portion and the second portion. A first side of each of the first body portion, the step portion and the second body portion are substantially aligned so that there is a step () defined on a second side opposite to the first side of the body portion. There is an aperture () in the step portion and an internal tube () extending from the aperture towards the first body portion. The internal tube is divided along part of its length into at least two smaller internal tubes () with the smaller internal tubes opening into the first lumen.

Thoracic aorta stent graft with access region

A deployment device for deploying a self-expanding branched stent graft. The device includes a branched stent graft retained on an introducer. The introducer includes a main catheter and an auxiliary catheter preloaded within the introducer and extending from distal the distal end of the stent graft, into the lumen of the stent graft and through an internal branch in the graft and out of the fenestration.

Branch stent graft deployment and method

A stent graft including a tubular wall with at least one fenestration including a peripheral reinforcement around at least part of the fenestration. There can also be a tubular extension. The side arm includes a stent and a cover and extends from and is in fluid communication with the fenestration and the stent graft. The stent may be a self expanding stent. The ring and/or tubular extension provides better support and sealing for an extension arm. The fenestration can be circular or if towards the ends of the stent graft may be in the form of a U-shape with an open end.

Fenestrated stent grafts

A composite stent graft has a balloon expandable stent portion, a tubular graft material portion inside or outside of the balloon expandable stent portion and self expanding stents associated with the tubular graft material portion. Part of the balloon expandable stent portion can extend beyond the proximal end of the tubular graft material portion. The tubular graft material can be polytetrafluoroethylene, dacron, polyamide, sub intestinal mucosa or any other suitable biocompatible material. A method of deploying which includes flaring a part of the balloon expandable stent portion is also discussed.

Composite stent graft

A stent graft has a tubular body with a first bifurcation with first and second legs extending from the bifurcation. One of the legs has a further bifurcation to define a side arm. The stent graft can be deployed into the vasculature of a patient with the tubular body being in an aorta of the patient, a first leg extending down an iliac artery, a second leg being directed towards a contralateral iliac artery and the side arm directed to an internal artery of one of the iliac arteries. One of the legs can include a valved aperture to enable the placement of an indwelling catheter therethrough.

Twin bifurcated stent graft

A composite stent graft has a balloon expandable stent portion (), a tubular graft material portion () inside or outside of the balloon expandable stent portion and self expanding stents () associated with the tubular graft material portion. Part () of the balloon expandable stent portion can extend beyond the proximal end () of the tubular graft material portion. The tubular graft material can be polytetrafluoroethylene, dacron, polyamide, sub intestinal mucosa or any other suitable biocompatible material. A method of deploying which includes flaring a part () of the balloon expandable stent portion is also discussed.

A deployment device for deploying a self-expanding fenestrated stent graft. The device includes a fenestrated stent graft retained on an introducer. The introducer includes a main catheter and an auxiliary catheter preloaded within the introducer and extending from distal the distal end of the stent graft, into the lumen of the stent graft and through the fenestration.

A stent graft () including a tubular wall () with at least one fenestration () including a peripheral () reinforcement around at least part of the fenestration. There can also be a tubular extension (). The side arm includes a stent () and a cover () and extends from and is in fluid communication with the fenestration and the stent graft. The stent may be a self expanding stent. The ring and/or tubular extension provides better support and sealing for an extension arm. The fenestration () can be circular or if towards the ends of the stent graft may be in the form of a U-shape () with an open end.

A method of assembling of a stent graft () including temporarily diameter reduction arrangements to enable partial release of a stent graft to assist with positioning before complete release. The diameter reduction arrangement includes a release wire () and flexible threads () extending to struts () of a self expanding stent () either side of the release wire and being pulled tight. Removal of the release wire enables full expansion of the self expanding stent.

Assembly of stent grafts

A stent graft () has at least one fenestration () or low profile side arm (). A guide assembly () surrounds the fenestration or low profile side arm. The guide assembly has a continuous wall extending laterally away from the outer surface of the stent graft. The continuous wall is substantially elliptical or circular and extends distally of the fenestration at a distal end of the wall and being coincident with a proximal part () of the periphery of the fenestration or low profile side arm at a proximal end of the wall (). The wall acts to define a guide area to guide a flexible probe extended from a side branch vessel to enter the fenestration or low profile side arm. Where there are two fenestrations or low profile side arms there can be a single continuous wall () around both or separate walls for each. The wall may have a peripheral wire reinforcement ().
