HEMANGIOMA BLOCKING DEVICE, HEMANGIOMA BLOCKING TREATMENT DEVICE AND HEMANGIOMA BLOCKING 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 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). The aneurysm occlusion device (10) provides the advantages of, among others, stably and compliantly packing the aneurysm (30) while avoiding its rupture, preventing vascular embolism, improving coverage of an opening at the neck of the aneurysm, promoting thrombosis in the aneurysm (30) and accelerating embolization of the aneurysm (30).
