Abstract

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.
