ABSTRACT:
The stent comprises a flexible self-expandable braided tubular wall having a proximal segment having an outer diameter, and a distal segment having an outer diameter smaller than the outer diameter of the proximal segment. An intermediate segment is formed between proximal and distal segments, which forms a truncated cone of which the base is forming the proximal end of the intermediate segment and of which the top is forming the distal end of the intermediate segment. A covering layer is arranged within the tubular wall.
