Elephant Trunk Thoracic Endograft and Delivery System
First Claim
1. A prosthesis delivery system comprising:
- a self-expandable stent-graft prosthesis with a first end, a second end and a length therebetween; and
a deployment device comprising;
an elongated outer sheath, the elongated outer sheath overlying the self-expandable stent-graft prosthesis and maintaining the first end of the self-expandable stent-graft prosthesis in a radially compressed state, said elongated outer sheath being retractable with respect to the self-expandable stent-graft prosthesis for radial self-expansion of the first end of the self-expandable stent-graft prosthesis from the radially compressed state upon retraction of the elongated outer sheath; and
a retaining member, the retaining member overlying and maintaining the second end of the self-expandable stent-graft prosthesis in a radially compressed state, the second end of the self-expandable stent-graft prosthesis being positioned inside the retaining member, the retaining member being independently retractable from the second end of the self-expandable stent-graft prosthesis for radial self-expansion of the second end of the self-expandable stent-graft prosthesis from the radially compressed state upon retraction of the retaining member;
wherein only the elongated outer sheath maintains the first end of the self-expandable stent-graft prosthesis in the radially compressed state and only the stent-graft retaining member maintains the second end of the self-expandable stent-graft prosthesis in the radially compressed state, and the retaining member and the elongated outer sheath are retractable in opposite directions.

Abstract
A delivery system for delivering a device within a body lumen. The delivery system includes a self-expanding stent/graft composite prosthesis and a deployment device. The deployment device includes an outer sheath which overlies the graft, and a stent retaining means for maintaining the one end of the stent in a radially compressed state. The outer sheath is retractable with respect to the graft, and the stent retaining means is removable to allow the stent end to radially expand. The deployment device may further include an inner sheath to overlie the composite and is retractable with respect to the composite. An endoluminal prosthesis including a graft attached to one stent and a second stent unattached within the graft lumen.

12. A delivery system comprising:
-
an elongated outer sheath, the elongated outer sheath having a sheath length, the elongated outer sheath being retractable in a first direction; a retaining member, the retaining member having a member length less than the sheath length, the retaining member being positioned longitudinally adjacent to the elongated outer sheath, the retaining member being retractable in a second direction opposite the first direction; a stent-graft having a first end, a second end, and a length therebetween, the stent-graft having a radially compressed state; wherein an entirety of the length of the stent-graft is maintained in the radially compressed state by the elongated outer sheath and the retaining member with the first end of the stent-graft being maintained in the radially compressed state only by the elongated outer sheath and the second end of the stent-graft being maintained in the radially compressed state only by the retaining member. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A delivery system for a stent-graft, the stent-graft having a first end, a second end and a length therebetween, the delivery system comprising:
-
an elongated outer sheath, the elongated outer sheath being retractable from the stent-graft in a first direction; a retaining member positioned longitudinally adjacent to the elongated outer sheath, the retaining member being retractable from the stent-graft in a second direction opposite the first direction; the delivery system having a first configuration wherein; both the elongated outer sheath and the retaining member maintain an entirety of the length of the stent-graft in a radially compressed state with only the elongated outer sheath maintaining the first end of the stent-graft in the radially compressed state and only the stent-graft retaining member maintaining the second end of the stent-graft in the radially compressed state; wherein the delivery system is in the first configuration. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
