METHOD OF DELIVERING ADVANCED ENDOVASCULAR GRAFT
First Claim
1. A method of treating a patient'"'"'s vasculature, comprising:
- delivering an endovascular graft in a constrained state to a target location within a patient'"'"'s vasculature with a delivery system, the endovascular graft including a tubular graft body section and a distal self-expanding member disposed distally of the graft body section and the endovascular graft being disposed within an outer tubular member of the delivery system;
retracting a distal section of the outer tubular member of the delivery system from the constrained endovascular graft;
repositioning the endovascular graft by manipulation of a proximal portion of the delivery system; and
deploying the distal self-expanding member of the graft by manipulation of a handle disposed on the proximal portion of the delivery system such that the distal self-expanding member engages tissue of the patient'"'"'s vasculature in which the graft is deployed and prevents axial migration of the graft due to blood flow within the patient'"'"'s vasculature.

Abstract
A flexible low profile delivery system for delivery of an expandable intracorporeal device, specifically, an endovascular graft, which has at least one belt circumferentially disposed about the device in a constraining configuration. The belt is released by a release member, such as a release wire, by retracting the wire from looped ends of the belt. Multiple belts can be used and can be released sequentially so as to control the order of release and placement of the endovascular graft. An outer protective sheath may be disposed about the endovascular graft while in a constrained state which must first be retracted or otherwise removed prior to release of the graft from a constrained state. The delivery system can be configured for delivery over a guiding device such as a guidewire. The delivery system can also be configured for delivery of bifurcated intracorporeal devices.
