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 The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.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 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

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 The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.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 an iliac side branch 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.

A method of sizing of a stent graft () including placement of fenestrations () to ensure access to side branch vessels () through the fenestrations when the stent graft is introduced into a body vessel and an assembly method for a stent graft including temporary diameter reduction arrangements to enable partial release of a stent graft to assist with positioning of fenestrations with respect to side branch vessels. The method includes spacing the fenestrations to be the same circumferential distance as the side branch vessels irrespective of the diameter of the stent graft.
