Abstract
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 Analysis
Total Claims: 12
Claim 1
Independent Claim
81 words
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.
Claim 2
Dependent Claim
