Abstract:
1. A multi-port stent graft delivery device and stent graft in combination therewith, the delivery device comprising; a guide wire catheter having a guide wire lumen therethrough; a handle assembly at a distal end of the guide wire catheter, the handle including a plurality of access ports; a nose cone dilator at the proximal end of the guide wire catheter; a sheath arrangement extending from the handle to the nose cone dilator, the sheath arrangement being coaxial with and surrounding the guide wire catheter and defining an annular access lumen between the guide wire catheter and the sheath arrangement; the stent graft being on the guide wire catheter and within the main sheath, the stent graft comprising a proximal end, a distal end, a peripheral wall defining a lumen therethrough and at least one fenestration in the peripheral wall; the proximal end of the stent graft being releasably retained by a retention and release arrangement distally of the nose cone dilator; at least one indwelling access sheath within the access lumen, the at least one indwelling access sheath extending from the or one of the access ports and the indwelling access sheath having a proximal end terminating distally of the stent graft; a dilator extending through the or each access sheath and comprising a dilator tip at the proximal end of the or each access sheaths, the dilator being able to be withdrawn through the access sheath, an indwelling guide wire within the or each dilator in its access sheath; the indwelling guide wire extending beyond the dilator tip through the stent graft and then exiting the at least one fenestration and then extending proximally within the main sheath; whereby 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 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.
