Stent graft
First Claim
1. A deployment system for deploying a stent graft within a passageway, comprising:
- a delivery catheter comprising an outer sheath, a proximal end, and a distal end;
a stent having a first end and a second end, the stent being supported within the outer sheath at a first axial position in a collapsed state within the deployment system;
a graft having a first end and a second end, the graft being supported within the outer sheath at a second axial position in a collapsed state within the deployment system;
at least one connecting element extending from the second end of the stent to the first end of the graft so as to connect the second end of the stent to the first end of the graft; and
one or more retraction elements attached to the graft, the one or more retraction elements extending to the proximal end of the delivery catheter, the one or more retraction elements being releasably attached to the second end of the graft;
wherein the second axial position is different than the first axial position such that no substantial portion of the stent overlaps any portion of the graft while the stent and graft are in the collapsed state within the deployment system;
wherein as the one or more retraction elements are retracted in a proximal direction the graft inverts and retracts so that at least a portion of the graft overlaps a portion of the stent in a deployed state.

Abstract
Some embodiments are directed to a deployment system for deploying a stent graft within a passageway, including a delivery catheter having an outer sheath, a proximal end, and a distal end, a stent having a first end and a second end, a graft having a first end and a second end, and at least one connecting element extending from the second end of the stent to the first end of the graft so as to connect the stent to the graft. In some embodiments, the stent can be supported within the outer sheath at a first axial position in a collapsed state, and the graft can be supported within the outer sheath at a second axial position different than the first axial position in a collapsed state, such that the stent does not overlap or substantially overlap the graft in the collapsed state within the deployment system.
