HEMANGIOMA OCCLUSION APPARATUS, HEMANGIOMA OCCLUSION TREATMENT APPARATUS, AND HEMANGIOMA OCCLUSION SYSTEM

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). The guide structure (12) has an expanded configuration, in which the guide structure forms a spiral shape by spiraling from a distal end (122) to the proximal end (121) thereof, and a collapsed configuration for delivery into the aneurysm (30) from the blood vessel. The aneurysm occlusion device (10) provides the advantages of, among others, achieving stable and compliant packing while avoiding rupture of the aneurysm, preventing vascular embolism, improving coverage of an opening at the aneurysm neck, promoting thrombosis in the aneurysm and accelerating embolization of the aneurysm.
