Patent ID: 7998186

Claim:
An introduction arrangement for a branched stent graft in combination with a branched stent graft, the branched stent graft being intended for deployment into the lumen of a vessel having a blind vessel extending therefrom; the branched stent graft comprising; a main tubular body, a distal end a proximal end, and a main lumen therethrough, at least one side arm extending from the main body and having a side arm lumen therethrough, the side arm lumen being in fluid communication with the main lumen, 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 comprising a nose cone dilator and a retention arrangement to retain the branched stent graft thereon distally of the nose cone dilator, the branched stent graft being retained on the introducer and a sheath on the introducer extending over the branched stent graft to the nose cone dilator, an indwelling catheter for each of said at least one side arm, each indwelling catheter extending from the distal end of the introducer through an introducer lumen in the introducer to the branched stent graft, each indwelling catheter then exiting from the introducer lumen at a distal end of the branched stent graft and each indwelling catheter then extending outside the main tubular body and then entering the distal end of the respective side arm through the side arm lumen and extending into the main lumen and then extending to the proximal end of the branched stent graft through the main lumen, each indwelling catheter comprising a guide wire extending therethrough, whereby the indwelling catheter and guide wire can be extended beyond the proximal end of the branched stent graft in use after the sheath has been at least partially withdrawn from the branched stent graft.
