  • Patent number: 10722387
    Abstract: The present invention relates to a stent graft and to an insertion system for the stent graft according to the invention. The stent graft comprises a stent graft portion with a self-expanding stent having successive rings of meandering supports and a first prosthesis material secured on the rings. On at least one of its rings, the stent graft portion has two loop-shaped fixing elements which are attached via a common fixing area and which are attached to the supports of the rings in such a way that, due to the fact that they are guided in opposite directions around the hollow cylindrical body, the latter is compressible. Furthermore, the insertion system according to the invention also has a pin element with which the loop-shaped fixing elements can be threaded on.

  • Patent number: 10667933
    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.
