Patent ID: 8709061

Claim:
A pre-loaded stent graft delivery device in combination with a stent graft, the 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 assembly including a multiport manifold; a nose cone dilator at a proximal end of the guide wire catheter, the nose cone dilator comprising a distal end and a distally facing capsule on the distal end of the nose cone dilator; a pusher catheter extending from the multiport manifold towards the nose cone dilator, the pusher catheter comprising a longitudinal pusher lumen therethrough and two longitudinal auxiliary lumens, the pusher catheter completely enclosing the two longitudinal auxiliary lumens radially, a sheath disposed coaxially over the pusher catheter, the guide wire catheter extending through the pusher lumen and the guide wire catheter able to move longitudinally and rotationally with respect to the pusher catheter, the pusher catheter comprising a proximal end spaced distally from the nose cone dilator and thereby defining between the proximal end of the pusher catheter and the nose cone dilator a stent graft retention region; the multiport manifold comprising two side ports and a through bore, the two side ports extending distally at an angle from the through bore; the pusher catheter further comprising two side apertures near its distal end and the two side apertures opening respectively from a radial side wall of the pusher catheter into the two auxiliary lumens, the pusher catheter being received into the through bore of the manifold such that the two side apertures open respectively from the radial side wall of the pusher catheter into the two side ports; a proximally extending exposed self expanding stent of the stent graft being releasably retained in the distally facing capsule on the distal end of the nose cone dilator; an indwelling access sheath within each auxiliary lumen, the indwelling access sheaths extending through respective side ports and into the manifold from external thereof and having a proximal end terminating distally of the stent graft; an indwelling guide wire within each access sheath; each indwelling guide wire extending proximally of the access sheath through the stent graft and each exiting a respective fenestration in the wall of the stent graft and extending proximally to the distally facing capsule; the proximal end of the pusher catheter comprising an attachment boss; a trigger wire extending out of a first aperture on the side of the attachment boss and engaging with the stent graft before re-entering the attachment boss through a second aperture on the side of the attachment boss.
