Abstract:
A luminal endoprosthesis assembly (1) at least partially delimits a prosthesis lumen (2), for implantation in an anatomical structure (3) that at least partially defines at least one cavity (4) and includes at least one pathological portion (13). The luminal endoprosthesis (1) has two or more layers (5, 6, 7). At least one layer (5, 6, 7) includes a threadlike element (8) forming an armor (9). The luminal endoprosthesis (1) includes an anchoring portion (10) for anchoring to an anatomical portion (11) of the walls of the cavity (4) of the anatomical structure (3), and a working portion (12) for facing the pathological portion (13) of the anatomical structure (3). The two or more layers (5, 6, 7) are separated from each other in the working portion (12) of the luminal endoprosthesis (1), avoiding connecting elements between one layer (5, 6, 7) and at least one adjacent layer.
