Abstract

The stent graft (10) comprises a cylinder comprising a graft material in the form of a film and a stent that supports the cylinder. Further, the stent graft (10) is inserted within a region from the ascending aorta to the sinus of valsalva, and the stent graft comprises cylindrical body section (11) arranged in the ascending aorta and the sinus of valsalva section (12) arranged in the sinus of valsalva and having an inner diameter larger than that of the body section (11).

Claims

1. A stent graft comprising a cylinder comprising a graft material in the form of a film, and a stent that supports the cylinder, characterized in that:

the stent graft is inserted within a region from ascending aorta to sinus of valsalva; and

the stent graft comprises a cylindrical body section arranged in the ascending aorta, and a sinus of valsalva section arranged in the sinus of valsalva and having an inner diameter larger than that of the body section.

2. The stent graft according to claim 1, wherein

the sinus of valsalva section has a length shorter than the length from the boundary between the sinus of valsalva and the ascending aorta to the opening of coronary artery.

3. The stent graft according to claim 1, wherein

the body section has a length shorter than the length from the boundary between the sinus of valsalva and the ascending aorta to the opening of brachiocephalic artery.

4. The stent graft according to claim 1, wherein

roentgen markers are arranged at the boundary between the body section and the sinus of valsalva section.

5. A stent graft comprising a cylinder comprising a graft material in the form of a film, and a stent that supports the cylinder, characterized in that:

an open window is formed in the cylinder; and

roentgen markers are arranged around the periphery of the open window.

6. The stent graft according to claim 5, wherein

the roentgen markers are arranged at the inside of the open window.

7. The stent graft according to claim 5, wherein

the open window is circular when the stent graft is extended, and the roentgen markers are arranged in four directions of the open window.

8. The stent graft according to claim 5, wherein

the roentgen markers are soldered to the stent.

9. The stent graft according to claim 5, wherein

the stent graft is inserted in aortic arch;

and

the open window is formed so as to enclose the openings of left subclavian artery, left common carotid artery, and brachiocephalic artery branching from the aortic arch.
