Patent Images
1. An endovascular delivery device, comprising:
- a nose cone dilator,a guide wire catheter having inner and outer surfaces, the inner surface defining a passageway with a longitudinal axis, and the outer surface having a plurality of openings radially located from the longitudinal axis;
a stent graft comprising a tubular body of a biocompatible material with a lumen therethrough, the tubular body having first and second ends, and a plurality of stents, the stent graft being mounted onto the delivery device for deployment therefrom and being positioned on the guide wire catheter which passes through the lumen of the stent graft;
a cannula attachment wire for releasably fastening a side of the stent graft to the guide wire catheter whereby the stent graft is temporarily affixed to the guide wire catheter along a length of the guide wire catheter defined by the length of the stent graft;
wherein the cannula attachment wire weaves in and out of the plurality of openings.

Abstract
A stent graft delivery system in which a stent graft (6) is retained on a delivery device (2) such that a longitudinal portion of the stent graft is releasably retained on the delivery device to bend therewith. The delivery device (2) has a guide wire catheter (3) and the stent graft is retained onto the guide wire catheter by a cannula attachment wire (24) that can be withdrawn.

20. A method of deploying a stent graft to a patient in need thereof, comprising:
-
providing an endovascular delivery device, comprising; a nose cone dilator, a guide wire catheter having inner and outer surfaces, the inner surface defining a passageway with a longitudinal axis, and the outer surface having a plurality of openings radially located from the longitudinal axis; a stent graft comprising a tubular body of a biocompatible material with a lumen therethrough, the tubular body having first and second ends, and a plurality of stents, the stent graft being mounted onto the delivery device for deployment therefrom and being positioned on the guide wire catheter which passes through the lumen of the stent graft; a cannula attachment wire for releasably fastening a side of the stent graft to the guide wire catheter whereby the stent graft is temporarily affixed to the guide wire catheter along a length of the guide wire catheter defined by the length of the stent graft; wherein the aligned openings substantially conform in shape to the cannula attachment wire; removing the cannula attachment wire.
