Abstract

The invention relates to the technical field of medical devices, in particular to an intracranial stent graft. The intracranial covered stent includes a stent body and a film coated on the stent body, the stent body is a self-expanding network tube structure formed by interconnecting a plurality of unit grids, and the film is covered on the The middle part of the stent body; the intracranial covered stent automatically expands to fit the vessel wall at body temperature, and can form a closed channel in the lesion vessel under the premise of keeping the parent artery unobstructed, so that the blood flow of the lesion is completely consistent with the normal blood circulation. Isolate and isolate the aneurysm, change the hemodynamics in the tumor, and promote the formation of thrombus. Compared with using coils or other embolic agents to treat aneurysms, the covered stent graft of the present application is more economical and simple, and can avoid the risk of aneurysm rupture and bleeding during the operation; compared with parent artery balloon occlusion or ligation, Stent-graft technology appears safer by preserving artery patency.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intracranial stent graft. Background technique [0002] At present, intracranial aneurysm refers to a tumor-like protrusion of the arterial wall caused by the localized abnormal expansion of the cerebral artery lumen. Intracranial aneurysms are mostly caused by local congenital defects of the cerebral artery wall and increased intracavitary pressure. Caused by cystic bulge, is the first cause of subarachnoid hemorrhage. Surgical clamping and vascular intervention are the two main modalities for the treatment of intracranial aneurysms. Among them, interventional treatment of intracranial aneurysms has become the first choice for many hospitals due to its characteristics of small trauma, high safety, and good postoperative healing. [0003] At present, the clinical interventional treatment of intracranial aneurysms is basically intracranial embolization coils. In 1995,...
