Stent for implantation in a blood vessel, especially in the region of the aortic arch
First Claim
1. A stent for implantation in a blood vessel, said stent having a proximal end and a distal end and comprising a plurality of rings, which are disposed successively in the stent'"'"'s longitudinal direction and which are made up of meandering circumferential supports, and further comprising a prosthesis material which is fixed to the rings and which connects them, said prosthesis material and said rings forming a hollow cylindrical body, the hollow cylindrical body having a circumference and forming a jacket which is substantially closed on the circumference and further comprising a last ring, a penultimate ring and a third last ring at the proximal end, wherein only between the last ring and the penultimate ring at the proximal end of the stent one V-shaped connecting support is provided and connects the last and penultimate rings to one another, and wherein apart from the last ring and the penultimate ring, which are connected via the V-shaped connecting support, the rings are only connected to one another by said prosthesis material, and wherein an area free of prosthesis material is braced between the last ring and the penultimate ring only in the area of the V-shaped connecting support.

Abstract
A stent for implantation in a blood vessel is disclosed, especially in the region of the aortic arch. The stent is comprising rings which are disposed successively in the stent'"'"'s longitudinal direction and which are made up of meandering circumferential supports. The stent further comprises a prosthesis material which is fixed to the rings and which connects them, thereby forming a hollow cylindrical body with a jacket which is substantially closed on the circumference thereof. At least one connecting support is provided between the last ring and the penultimate ring at the proximal end of the stent and connects these two rings to one another.

21. A stent, comprising:
- a plurality of circumferential supports disposed successively in a longitudinal direction; and
a prosthesis material which is fixed to at least one of the plurality of circumferential supports and which connects the plurality of circumferential supports, said prosthesis material and said circumferential supports together forming a hollow substantially cylindrical body with a jacket which is substantially closed on a circumference thereof, and further comprising a last circumferential support and a penultimate circumferential support at a proximal end of the stent, wherein only between the last circumferential support and the penultimate circumferential support at the proximal end of the stent one V-shaped connecting support is provided and connects the last and penultimate circumferential supports to one another, and wherein apart from the last circumferential support and the penultimate circumferential support, which are connected via the V-shaped connecting support, the circumferential supports are only connected to one another by said prosthesis material, and wherein an area free of prosthesis material is braced between the last circumferential support and the penultimate circumferential support only in the area of the V-shaped connecting support.
