Introducer for a side branch device
First Claim
1. A stent graft introduction arrangement in combination with a fenestrated stent graft, the fenestrated stent graft being intended for deployment into a lumen of a vessel having a blind vessel extending therefrom,the fenestrated stent graft comprising a main tubular body, a distal end, a proximal end, a main lumen therethrough, and at least one fenestration in the main body between the distal end and the proximal end of the fenestrated stent graft,the introduction arrangement including an introducer, the introducer comprising a distal end intended to remain outside a patient in use and a proximal end, the proximal end of the introducer comprising a nose cone dilator and retention arrangement to retain the fenestrated stent graft thereon distally of the nose cone dilator, the fenestrated stent graft being retained on the introducer and a sheath on the introducer extending over the fenestrated stent graft to the nose cone dilator,an indwelling catheter for each of said at least one fenestration, each indwelling catheter extending from the distal end of the introducer through an introducer lumen in the introducer to the fenestrated stent graft, each indwelling catheter then exiting from the introducer lumen at a distal end of the fenestrated stent graft, each indwelling catheter then extending outside and along the main tubular body, then entering the respective fenestration and extending into the main lumen and then extending to the proximal end of the fenestrated stent graft through the main lumen, each indwelling catheter configured to receive a guide wire extending therethrough,whereby the indwelling catheter and the guide wire can be extended beyond the proximal end of the fenestrated stent graft in use after the sheath has been at least partially withdrawn from the fenestrated stent graft.

Abstract
An introduction arrangement for a fenestrated or branched stent graft (13) intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer (1) has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator (11) and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath (15) on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter (21) 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 (29) 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.
