Technical Field
The invention relates to the field of medical equipment, in particular to an aneurysm embolism device and an aneurysm embolism system applied to aneurysm interventional therapy.
Background
Aneurysms are very common vascular diseases, which are the manifestations of limitation or diffuse expansion or distension of the arterial wall due to lesions or injuries of the arterial wall, and which are mainly manifested as distending, pulsating masses, which can occur in any part of the arterial system. Once the aneurysm ruptures, serious consequences may occur. If the intracranial aneurysm breaks, the subarachnoid hemorrhage is caused, and serious cases can cause vascular spasm to cause wide cerebral infarction, thereby causing hemiplegia, coma and the like. Current treatment regimens for aneurysms are mainly open surgery and endovascular interventions. The open surgical treatment scheme requires opening the body cavity surrounding the aneurysm, such as craniotomy and thoracotomy, causing great damage to the patient's body and long postoperative recovery period. The intravascular interventional therapy of the aneurysm is the preferred clinical treatment scheme of a plurality of medical professionals at present due to the advantages of minimally invasive, safe and effective intravascular interventional therapy of the aneurysm.
Currently, the endovascular interventional treatment technology of aneurysms mainly comprises a spring coil embolism technology, a spherical embolism technology, a blood flow guiding device and the like. The disadvantage of coil embolization is the increased cost due to the placeholder effect and the need for additional stent assistance. The drawbacks of the balloon embolization are the placeholder effect, the adaptation to only specific aneurysm shapes and the need for stent assistance, which leads to increased costs. Blood flow guides suffer from the disadvantages of delayed rupture of the aneurysm, occlusion of other small branches, and increased cost and space occupation effects that may be caused by the need for a packing coil assist.
Accordingly, in view of the above shortcomings, there is a need to provide an aneurysm embolization device that reduces the placeholder effect, saves costs, accommodates aneurysms of different aneurysm shapes, different sites, and reduces the risk of delayed rupture of the aneurysm and avoids occluding other branches.
