1. A system for the delivery and deployment of an endovascular graft comprising:
- a. a delivery device comprising;
i. a pusher catheter having a proximal end portion a distal end portion and a lumen extending there between, and a proximal end opening;
ii. a cannula having a proximal end portion and a distal end portion extending longitudinally within the lumen of the pusher catheter;
iii. a nose cone dilator proximal of the proximal end portion of the cannula, the nose cone dilator having a proximal tip;
iv. an extension sheath extending from the proximal tip of the nose cone dilator, the extension sheath having a lumen extending there through, wherein a portion of the extension sheath has a U-shaped configuration;
b. a stent graft carried on the delivery device, the stent graft comprising;
i. a main tubular body of a biocompatible graft material defining a main lumen having a proximal end portion, a distal end portion, a distal end opening;
ii. a side branch extending from the main tubular body, the side branch defining a lumen and being in fluid communication with the main lumen, whereby the stent graft is configured to be deployed into the vasculature of a patient with the main tubular body being located in the ipsilateral common iliac artery and the side branch being directed towards an internal iliac artery of the common iliac artery;
c. a pre-loaded guide wire extending through the lumen of the pusher catheter, exiting the proximal end opening of the pusher catheter distal to the distal end opening of the main tubular body, extending entirely outside of the distal portion of the main tubular body along side the main tubular body and entering the main lumen of the main tubular body through the lumen of the side branch and extending out of the proximal end portion of the main tubular body, the pre-loaded guide wire further extending at least partially through the lumen of the extension sheath.

10. A method for treating a diseased vessel, the method comprising:
-
a. introducing a delivery device into an ipsilateral common iliac artery, the delivery device comprising; i. a pusher catheter having a proximal end portion, a distal end portion and a lumen extending there between, and a proximal end opening; ii. a cannula having a proximal end portion and a distal end portion extending longitudinally within the lumen of the pusher catheter; iii. a nose cone dilator proximal of the proximal end portion of the cannula, the nose cone dilator having a proximal tip; iv. an extension sheath extending from the proximal tip of the nose cone dilator, the extension sheath having a lumen extending there through, wherein a portion of the extension sheath has a U-shaped configuration; v. a stent graft carried on the delivery device, the stent graft comprising a main tubular body of a biocompatible graft material defining a main lumen having a proximal end portion, a distal end portion, a distal end opening, a side branch extending from the main tubular body, the side branch defining a lumen and being in fluid communication with the main lumen, whereby the stent graft is configured to be deployed into the vasculature of a patient with the main tubular body being located in the ipsilateral common iliac artery and the side branch being directed towards an internal iliac artery of the common iliac artery; vi. a pre-loaded guide wire extending through the lumen of the pusher catheter, exiting the proximal end opening of the pusher catheter distal to the distal end opening of the main tubular body, extending entirely outside of the distal portion of the main tubular body along side the main tubular body and entering the main lumen of the main tubular body through the side branch lumen and extending out of the proximal end portion of the main tubular body, the pre-loaded guide wire having a proximal end portion extending at least partially through the lumen of the extension sheath, b. extending the extension sheath and proximal end portion of the pre-loaded guide wire over the aortic bifurcation and in a distal direction down the contralateral common iliac artery. - View Dependent Claims (11, 12, 13, 14, 15, 16)
