  • Publication number: 20230329719
    Abstract: An aneurysm occlusion device (10), a therapeutic apparatus for aneurysm occlusion and an aneurysm occlusion system. The aneurysm occlusion device (10) includes an expandable mesh structure (11) and a guide structure (12). The expandable mesh structure (11) has an expanded configuration, in which it assumes a spiral shape spiraling from a distal end (111) to a proximal end (112) thereof, and a collapsed configuration for its delivery into an aneurysm (30) from a blood vessel. At least a portion of the guide structure (12) is disposed in an inner cavity defined by the expandable mesh structure (11) and, when the expandable mesh structure (11) is in the spiral shape, expands into a spiral shape in the inner cavity of the expandable mesh structure (11).

  • Publication number: 20230320733
    Abstract: An aneurysm occlusion device (10), a therapeutic apparatus for aneurysm occlusion and an aneurysm occlusion system. The aneurysm occlusion device (10) includes an expandable structure (11) and a guide structure (12). The expandable structure (11) is a three-dimensional mesh. The expandable structure (11) has an expanded configuration, in which the expandable structure forms a spiral shape by spiraling from a distal end (111) to a proximal end (112) thereof, and a collapsed configuration for delivery into an aneurysm (30) from a blood vessel. The guide structure (12) is provided at the distal end (111) of the expandable structure (11). The proximal end (121) of the guide structure (12) is connected to the distal end (111) of the expandable structure (11).

  • Publication number: 20230310004
    Abstract: An aneurysm occlusion device (10), a therapeutic apparatus for aneurysm occlusion and an aneurysm occlusion system are disclosed. The aneurysm occlusion device (10) includes at least an expandable mesh structure (11) having an expanded configuration with a planar spiral shape and a compressed configuration for delivery into an aneurysm (30) from a blood vessel. The expandable mesh structure (11) can be compressed within a catheter (40) and can recover the expanded configuration with the spiral shape after being released from the catheter (40). The aneurysm occlusion device (10) achieves stable, compliant packing while providing the advantages of among others, avoiding rupture of the aneurysm (30), preventing thrombosis in a blood vessel, increasing coverage of an opening at the aneurysm neck, promoting thrombosis in the aneurysm and accelerating embolization of the aneurysm (30).
