Description
Technical Field
The invention relates to the field of vascular remodeling, in particular to an abdominal artery remodeling device.
Background
The size, shape, and/or patency of a lumen within a patient can vary, and these variations can lead to complications or affect related bodily functions. For example, the walls of the vasculature, particularly the arterial walls, may develop into pathological dilations commonly referred to as aneurysms. Aneurysms are observed as the dilation of the arterial wall. This is because the vessel wall becomes weakened by disease, injury, or congenital malformations. Aneurysms have weak walls, have a tendency to rupture, and are often caused by or exacerbated by high blood pressure. Aneurysms can be found at different parts of the body; the most common are Abdominal Aortic Aneurysms (AAA) and brain or cerebral aneurysms. While the mere presence of an aneurysm is not always life threatening, it can cause a range of health problems, for example, a stroke if the aneurysm ruptures in the brain. In addition, ruptured aneurysms can also lead to death.
The existing treatment is to replace the artificial blood vessel with the excision of a section of the artery with the aneurysm. However, when the aneurysm is located close to the branch vessel 31, as shown in fig. 7, if the artificial blood vessel is installed after the artery is removed, the branch vessel is clogged. In the prior art, a biological patch is adopted for carrying out blood vessel extraluminal remodeling, but after the existing biological patch is subjected to extraluminal remodeling, the biological patch needs to be bound on the outer surface of a blood vessel by using a suture line, and because the suture line is in line contact with the outer surface of the blood vessel, if the suture line is excessively stressed, the blood vessel is cut, and the biological patch is wound and loosened due to excessively weak stress, so that the blood vessel remodeling effect cannot be achieved.
