Embodiment Construction

[0057] Please refer to the attached figure 1 , with figure 1 A schematic structural view of the stent graft system provided by the embodiment of the present application is shown. attached by figure 1 It can be seen that the stent graft system provided by the embodiment of the present application includes a stent subsystem 01 and a delivery subsystem 02, wherein the stent subsystem 01 includes an aortic stent 1 and a side branch stent 2, and the delivery subsystem 02 includes a delivery device 3, an adjustable Valve sheath 4 and conveyor 5. According to the aortic vessel and / or important branch vessels involved in the patient's lesion, such as the arterial arch, the celiac trunk to the renal artery, etc., the stent subsystem 01 in the embodiment of the present application realizes the multi-branch vessel in the cavity through combination. Reconstruction, such as a combination of an aortic stent 1 and a side branch stent 2, or a combination of an aortic stent 1 and two side b...

Abstract

The invention provides a covered stent system. The covered stent system is simple in structure, clear in principle, flexible and diverse in combinations and relatively few in required stent specifications, achieves limited stent specifications and meets the requirements for different vascular anatomical structures. Various stents in a stent sub-system are fast in release, and blood flow, deep hypothermic circulatory and extracorporeal circulation do not need to be blocked, so that the surgical operation difficulty is greatly reduced, the operation time is shortened, and the perioperative mortality and complication can be greatly reduced. In addition, the operation time is shortened and the operation difficulty is reduced, so that the amount of a contrast medium can be reduced, and meanwhile, the irradiation time that a doctor and a patient are exposed to radioactive rays is significantly shortened. The covered stent system provided by the invention can achieve endovascular exclusion treatment from single-branched vessels to multibranched vessels, for example, endovascular exclusion treatment from arcus aortae and celiac trunks to renal arteries.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent graft system. Background technique [0002] With the improvement of living standards in our country, the aging population and the popularization of automobiles, the incidence of aortic diseases such as aortic dissection, aneurysm, hematoma and traumatic aortic diseases caused by automobile accidents is increasing day by day. Aortic disease can cause clinical symptoms such as arteriosclerosis, arterial thrombosis, and Raynaud's syndrome depending on the condition, and can cause heart failure, cardiogenic shock, and death in severe cases. [0003] At present, the treatment of aortic disease mainly includes conservative drug treatment, open surgical treatment and aortic endovascular interventional treatment. Among them, aortic endoluminal interventional therapy refers to the treatment of placing a covered stent at the lesion, isolating the blood vessels at the lesio...
