A stent graft for placement in a vessel of a patient, the stent graft that has a tubular body of graft material, the tubular body having a proximal inflow end, a distal outflow end, a main lumen therethrough, a longitudinal access, and a sidewall from the first end to the second end. At least one stent is along the length of the tubular body. One or more shaped recesses are formed of a concave or recessed portion of graft material that extends into the lumen of the stent graft. A fenestration is in the recessed portion with a fenestration and an internal branch extends from the or each fenestration toward the proximal end of the tubular body of graft material. The internal branch may have a tubular portion and a funnel portion, wherein the tubular portion extends into the main lumen and the enlarged funnel portion is attached to sidewall and forms the at least one shaped recess.

Thoracic aorta stent graft

A joining arrangement between a main tube and a side arm () in a side arm stent graft (). The side arm () is stitched into an aperture () in the main tube and is in fluid communication with it. The aperture is triangular, elliptical or rectangular and the side arm is cut off at an angle to leave an end portion having a circumferential length equal to the circumference of the aperture. The side arm can also include a connection socket () comprising a first resilient ring () around the arm at its end, a second resilient ring () spaced apart along the arm from the first ring and a zig zag resilient stent () between the first and second rings. The zig-zag resilient stent can be a compression stent. Both the main tube and the side arm are formed from seamless tubular biocompatible graft material.

Side branch stent graft

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

An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis. The branch vessel prosthesis is deployable within a branch vessel body lumen and comprises a stent having a generally tubular body portion, a flareable proximal end portion, and a coupling portion disposed intermediate the body portion and the flareable portion. The coupling portion is more crush-resistant than the body portion. The flareable proximal end may be disposed within a fenestrated stent graft with coupling portion disposed in the fenestration of the fenestrated stent graft.

Stent with a crush-resistant zone

An introduction arrangement for a fenestrated or branched stent graft intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter extends from the distal end of the introducer and enters the fenestration or side arm and through to the nose cone dilator, the indwelling catheter has a guide wire extending through it. The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.

Introducer for a side branch device

A joining arrangement between a main tube () and a side arm () in a side arm stent graft (). The side arm () is stitched into an aperture () in the main tube and is in fluid communication with it. The aperture is triangular, elliptical or rectangular and the side arm is cut off at an angle to leave an end portion having a circumferential length equal to the circumference of the aperture. The side arm can also include a connection socket () comprising a first resilient ring () around the arm at its end, a second resilient ring () spaced apart along the arm from the first ring and a zig zag resilient stent () between the first and second rings. The zig-zag resilient stent can be a compression stent. Both the main tube and the side arm are formed from seamless tubular biocompatible graft material.

A stent graft for placement in the thoracic arch of a patient has a tubular body defining a main lumen therethrough, a plurality of zig zag stents along the tubular body, each of the stents comprising a plurality of struts and bends, the bends being between adjacent struts. At least a first stent and an adjacent second stent having at least a pair of adjacent bends on the first stent aligned with an adjacent pair of bends on the second stent, whereby a first pair of adjacent struts of the first stent and a second pair of adjacent struts of the second adjacent stent together define a diamond shape region. A recess is within the diamond shaped region with the recess extending into the lumen of the tubular body. A fenestration extending into the tubular body within the recess in the diamond shaped region and a graft tube leading from the fenestration into the main lumen. There can be one, two or three diamond shaped regions, recesses, fenestrations and graft tubes. Proximally of the or each diamond shaped region the tubular body has a first diameter, distally of the diamond shaped region the tubular body has a second diameter and in the region of the tubular body around the diamond shaped region the tubular body has a third diameter, the first diameter being greater than the second diameter and both the first and second diameter being greater than the third diameter whereby a central region is defined which will allow circumferential blood flow during an operation out of the graft tube into the recess and then into the central 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 pre-loaded stent graft delivery device and stent graft, the stent graft delivery device. The stent graft has at least one fenestration or side arm and the fenestration is preloaded with an indwelling guide wire. The indwelling guide wire are configured to receive the access sheaths. A handle assembly at a distal end of the guide wire catheter. The handle includes a multiport manifold with access ports to the auxiliary lumens in the pusher catheter. Upon deployment of the stent graft into the vasculature of a patient, the indwelling guide wire can be used to facilitate catheterization of a side branch or target vessel through the fenestration or be used to stabilize the access sheath during catheterization, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.

Pre-loaded multiport delivery device

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.
