Abstract

The invention relates to an aneurysm embolism device. The aneurysm embolism device comprises an embolism device, a pushing wire and a leading-in sheath, wherein the embolism device and the pushing wire are pre-installed in the leading-in sheath, the embolism device is connected with the pushing wire, and one end of the pushing wire extends to the outside of the leading-in sheath. The aneurysm embolism device can be released and recycled for multiple times, the operation difficulty is reduced, and while an aneurysm is effectively embolized, the aneurysm-carrying aneurysm and branch occlusion are avoided; instrument displacement can be effectively avoided, and the displacement risk after the aneurysm is filled is reduced; and the aneurysm embolism device can be used for treating aneurysms atdifferent positions and in different forms. The aneurysm embolism device is applied to the technical field of medical instruments.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an aneurysm embolization device. Background technique [0002] Aneurysm is a manifestation of localized or diffuse expansion or bulging of the arterial wall due to lesion or injury of the arterial wall, and rupture of the aneurysm can lead to hemorrhagic stroke or even sudden death. At present, the main treatment methods for intracranial aneurysms are: (1) Surgical clipping; (2) Balloon or stent-assisted coil embolization; (3) Reconstruction of the parent artery with a blood flow diversion device. From surgical clipping to vascular reconstruction, the treatment of intracranial aneurysms has changed from craniotomy to minimally invasive surgery, which reduces the difficulty of intracranial aneurysm treatment operations, relieves the pain of patients, and gradually improves the cure rate of aneurysms. And the recurrence rate is gradually reduced, but the most commonly used...
