STENT GRAFT AND INTRODUCER ASSEMBLY
First Claim
1. A stent graft configured for treatment of defects in the ascending aorta, the stent graft including a tubular portion of graft material provided with proximal and distal ends, a plurality of stent rings attached to the graft tube, at least one bare stent extending from the proximal end of the graft tube and designed to flare outwardly relative to the graft tube so as to engage in use the cavity of the aortic sinus of a patient.

Abstract
A stent graft (40) for treating Type-A dissections in the ascending aorta (22) is provided with a plurality of diameter-reducing suture loops (56-60) operable to constrain the stent graft during deployment thereof in a patient'"'"'s aorta. The diameter-reducing loops (56-60) allow the stent graft (40) to be partially deployed, in such a manner that its location can be precisely adjusted in the patient'"'"'s lumen. In this manner, the stent graft can be placed just by the coronary arteries (26, 28) with confidence that these will not be blocked. The stent graft (40) is also provided with proximal and distal bare stents (44,52) for anchoring purposes.

8. A stent graft according to claim 8, wherein the second diameter-restraining device is located substantially half-way along the graft tube.
- 17. A stent graft including a tubular portion of graft material comprising proximal and distal ends, a plurality of stent rings attached to the graft tube and at least first and second diameter-restraining devices, the first diameter-restraining device being located proximate the proximal end of the graft tube, at least one second diameter-restraining device being located in an intermediate position along the graft tube.

20. A method of treating a vascular defect in the ascending aorta of a patient including the steps of locating in the ascending aorta a stent graft provided with a tubular portion of graft material provided with proximal and distal ends, a plurality of stent rings attached to the graft tube, at least one bare stent extending from the proximal end of the graft tube and designed to flare outwardly relative to the graft tube, said positioning locating the bare stent in the aortic sinus of a patient so as to anchor the stent graft in position.
