A delivery system is equipped with a self expanding stent for implantation into a blood vessel, in particular in the region of the aortic arch. The stent has a hollow cylindrical body which is radially compressed for implantation. A pull-back sheath which surrounds the stent and which radially compresses it is also provided for positioning and releasing the stent in the blood vessel. The pull-back sheath has a highly flexible front section which surrounds the stent and which maintains said stent in its compressed state, and has further a more rigid rear section which is connected to the front section and which is designed to transmit torsional and traction forces to the front section.

Stent for implantation in a blood vessel, especially in the region of the aortic arch
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.
