1. A stent graft delivery system, comprising:
- a stent graft having a proximal portion and a distal portion;
a proximal sheath configured to cover the proximal portion of the stent graft; and
a distal sheath configured to cover the distal portion of the stent graft, wherein the proximal sheath and the distal sheath are independently removable from respective ends of the stent graft such that the proximal and distal portions of the stent graft are independently deployable.

Abstract
Stent graft delivery systems are disclosed herein. In several embodiments, a stent graft delivery system can include a stent graft having a proximal portion and a distal portion, a proximal sheath and a distal sheath. The proximal sheath can be configured to cover the proximal portion of the stent graft, and the distal sheath can be configured to cover the distal portion of the stent graft. The proximal sheath and the distal sheath can be independently removable from respective ends of the stent graft such that the proximal and distal portions of the stent graft are independently deployable.

11. A method of delivering a stent graft, the method comprising:
-
delivering to an aortic aneurysm a stent graft with a proximal sheath covering a proximal portion of the stent graft and a distal sheath covering a distal portion of the stent graft; positioning the distal portion of the stent graft above the aortic aneurysm; retracting the proximal sheath relative to the stent graft to deploy the proximal portion of the stent graft; advancing the distal sheath relative to the stent graft to deploy the distal portion of the stent graft via a central wire; and retracting the distal sheath through an inner lumen formed by the stent graft. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An endograft deployment system, comprising:
-
a sheath selectably covering an expandable stent graft, the stent graft having a proximal portion and a distal portion, an elongated length while in a sheathed state, and a shortened length while in a deployed state; and a deployment device having a gear arrangement with a gear ratio configured to advance the stent graft while simultaneously retracting the sheath relative to the stent graft such that the distal portion of the stent graft is maintained at a single position while transitioning from the sheathed state to the deployed state. - View Dependent Claims (21)
