Patent number: 10722387Abstract: 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.Type: GrantFiled: November 3, 2017Date of Patent: July 28, 2020Assignee: JOTEC GmbHInventors: Franz-Peter Barthold, Marcos Centola, Christian Woerne
