A stent prosthesis for vascular surgery for inserting into an artery, particularly for bridging a vascular enlargement in the area of the aortic arch, comprising a tubular flexible and radially expandable stent body, on which at least one tear-proof long thread is attached in a fixed manner at a point of attachment on the outer peripheral surface of the stent body in the front portion thereof The thread can be recognized under x-ray radiation and has a free thread length of a number of decimeters and, starting from the point of attachment, is exposed outside the stent body so that the stent body, while following the thread, can be passed into the artery and can be placed, by means of the thread, in position inside the artery and can be subsequently fixed to the vascular wall. |
