Multi-port delivery device
First Claim
1. A multi-port stent graft 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;
a stent graft 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 handle and having a proximal end terminating distally of the stent graft;
an indwelling guide wire within the or each access sheath;
the indwelling guide wire extending through the stent graft and exiting the at least one fenestration and 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 cathertisation of a side branch or target vessel or be used to stabilise the access sheath during catheterisation, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.

Abstract
A multi-port stent graft delivery device (2) has an annular access lumen (26) between a delivery catheter (24) and a main sheath (6), at least one indwelling access sheath (28, 30) within the access lumen, and an indwelling guide wire (36, 38) within the or each access sheath and a stent graft (16) retained in the delivery device. Upon deployment of the stent graft into the vasculature of a patient the indwelling guide wire can be used to facilitate stabilisation of the access sheath during cathertisation of a side branch and deployment of a side arm covered or uncovered stent therein through the advanced access sheath. A manifold associated (4) with a handle provides a plurality of access ports (41, 43). A docking balloon may also be used.
