Claim:
1. A device for treating a vessel comprising: an expandable stent graft having a main lumen and a target portion; a primary sleeve and a secondary sleeve each wrapped circumferentially around a common portion of the expandable stent graft, each of the primary and secondary sleeves having a sheet of material with opposite first and second major surfaces and a plurality of openings each extending between the first and second major surfaces, at least one of the primary and secondary sleeves having a lateral opening proximate to the target portion and extending between the first and second major surfaces; a primary coupling member cooperating with the first plurality of openings for releasably coupling portions of the sheet of material to one another to form a first seam to constrain the expandable stent graft in a collapsed configuration for delivery within the vessel, the primary coupling member being configured to be removed from the primary sleeve during release of the first seam; and a secondary coupling member cooperating with the second plurality of openings for releasably coupling portions of the sheet to one another to form a second seam to restrict expansion of the expandable stent graft toward an intermediate configuration after displacement of the primary coupling member from the first plurality of openings, the intermediate configuration being larger than the collapsed configuration and smaller than a fully deployed configuration engaged with the vessel.
