Abstract
A stent-graft deployment system () includes a stent-graft (), a flexible catheter tip () attached to a catheter shaft (), a retractable primary sheath () containing the stent-graft in a first constrained small diameter configuration around the catheter shaft near the flexible tip. The stent-graft deployment system further includes a flexible secondary sheath () disposed within the retractable primary sheath and also containing the stent-graft, wherein when the primary sheath is removed from around the stent-graft, the flexible secondary sheath contains the stent-graft in a second constrained small diameter configuration around the catheter shaft near the flexible tip. The removal of the secondary sheath releases the stent-graft from a radial constraint so that stent-graft deployment may proceed.
