The endoprosthesis comprises a one-piece tubular structure made up of zigzag lengthwise members (5a, 5b) which are basically parallel to the endoprosthesis' lengthwise axis and are joined by articulated Z-shaped cross-members (7, 17, 27, 37) which connect the convex zones (9) of adjacent lengthwise members. The lengthwise and cross-members of the endoprosthesis form Z-shaped (15) cells which become hexagonal in shape when the endoprosthesis is expanded after implantation. |
