Abstract

A stent made of a self-expandable or balloon-expandable metal mesh fabric that can be widened to a diameter larger than that of the descending aorta. The stent has a flexible lining of vessel-replacing material, wherein the lining covers it at least partly in longitudinal direction and forms a tubular segment which projects beyond the end of the stent at least at one end and which functions as the vascular prosthesis. Such implantable arrangements (1) make it possible to achieve short surgical times, especially during the treatment of aortic arch aneurysms involving the cephalic arteries.

Claims

1. An implantation device for an aorta in an aortic arch comprising:

a) a stent made from self-expandable metal mesh fabric that can be widened to a diameter larger than that of the aorta;

b) a flexible lining of vessel replacing material wherein said flexible lining is attached to an inner and an outer wall of said stent wherein said flexible lining contains a tubular segment which projects beyond an end of said stent and functions as a vascular prosthesis.

3. The device of claim 1, wherein said flexible lining is made from tissue compatible plastic.

5. An arrangement as in claim 1, wherein said flexible lining of said stent and said tubing segment, projecting beyond said stent, are each made from different materials.

7. The device as in claim 5, wherein said lining is made from dracon and said protecting tubing segment is made of material having a density substantially similar to blood.

9. The device as in claim 1, wherein said lining covers between 20% and 90% of said stent, extending in a longitudinal direction from a distal end relative to a user'"'"'s heart.

2. An implantation device for an aorta in an aortic arch comprising:

a) a stent made from balloon expandable metal mesh fabric that can be widened to a diameter larger than that of the aorta;

b) a flexible lining of vessel replacing material wherein said flexible lining is attached to an inner and an outer wall of said stent wherein said flexible lining contains a tubular segment which projects beyond an end of said stent and functions as a vascular prosthesis.

4. The device of claim 2, wherein said flexible lining is made from tissue compatible plastic.

6. An arrangement as in claim 2, wherein said flexible lining of said stent and said tubing segment, projecting beyond said stent, are each made from different materials.

8. The device as in claim 6, wherein said lining is made from dracon and said protecting tubing segment is made of material having a density substantially similar to blood.

10. The device as in claim 2, wherein said lining covers between 20% and 90% of said stent, extending in a longitudinal direction from a distal end relative to a user'"'"'s heart.
