Intracranial film laminating support

Abstract

The invention relates to the technical field of medical apparatuses, in particular to an intracranial film laminating stent. The intracranial film laminating stent comprises a stent body and laminatedfilm covering the stent body, the stent body is a self-swelling net pipe structure connected by multiple unit grids, and the laminating film covers the middle of the stent body; the intracranial filmlaminating stent automatically spreads to adhere to a vascular wall under body temperature, on the premise of keeping the parent artery smooth, a sealed pipe can be formed in the lesion blood vessel,so that blood flow of the lesion part and normal blood circulation are completely isolated, the arterial aneurysm is isolated, blood flow dynamics in the tumor body is changed, and the formation of the thrombus is promoted. Compared with treating arterial aneurysm through a spring ring or other emboliazing agents, the intracranial film laminating stent is more economical and simpler, and the danger of arterial aneurysm fracture and bleeding can be avoided; compared with parent artery detachable balloon occlusion or ligation, the artery can be kept smooth to look safer according to a film covering stent technology.

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,...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an intracranial covered stent to solve the problem of mass effect caused by giant intracranial aneurysms after electrolytic coil embolization, the aneurysm cannot be densely packed, and the neck of the wide-necked aneurysm remains and Aneurysm recurrence, etc., fusiform aneurysm aneurysm cavity is irregular in shape, and there is no obvious boundary between the tumor cavity and the normal vessel cavity. Endovascular therapy with stent-assisted coils cannot effectively remodel the lumen in fusiform aneurysms shape problem
