Endoprosthesis and a method of producing an endoprosthesis

A stent-graft having a longitudinal axis, comprising:

• a tubular stent;
• a tubular graft attached to the tubular stent;
• at least two discrete support strips attached to an outer surface of the tubular graft, wherein each of the at least two discrete support strips have an elongated shape running in a direction parallel to the longitudinal axis of the stent graft;
• a plurality of thrombogenic fibers attached to each of the at least two discrete support strips;
• and
• at least two discrete fixation strips attaching the plurality of thrombogenic fibers to the stent-graft, wherein each of the at least two discrete fixation strips have an elongated shape complementary to the shape of the at least two discrete support strips;
• wherein each of the at least two discrete support strips are arranged between the tubular graft and a respective one of the at least two discrete fixation strips;
• wherein a first end portion of the plurality of thrombogenic fibers is arranged between a respective one of the at least two discrete fixation strips and the tubular graft and a second end portion of the plurality of thrombogenic fibers radially extends from the respective one of the at least two discrete fixation strips and the tubular graft to a free end.
