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 stents 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.
