Abdominal artery remodeling device

Abstract

An abdominal artery remodeling device provided by the present invention includes a flexible vascular patch and a connecting body, one end of the vascular patch is a suture end, and the other opposite end is a cutting end, and the cutting end can be cut by a scalpel; The coupling body is installed on the suture end of the blood vessel patch; wherein, the cut end of the blood vessel patch is allowed to be bent to the side close to the suture end to connect with the coupling body to form a tubular cavity, and the cavity is used for The outer peripheral surface of the wrapped blood vessel acts as a bracket. The abdominal artery remodeling device provided by the present invention performs remodeling outside the artery lumen, so as to reduce damage to branch vessels.

Description

technical field [0001] The invention relates to the field of blood vessel remodeling, in particular to an abdominal artery remodeling device. Background technique [0002] The size, shape and / or patency of lumens in a patient can change, and these changes can lead to complications or affect related bodily functions. For example, walls of the vasculature, especially arterial walls, may develop pathological dilations commonly referred to as aneurysms. An aneurysm is observed as a swelling of the artery wall. This is because the walls of blood vessels are weakened by disease, injury, or birth defects. Aneurysms have weak walls that tend to rupture and are usually caused by or worsened by high blood pressure. Aneurysms can be found in different parts of the body; the most common are abdominal aortic aneurysms (AAA) and brain or cerebral aneurysms. Although the mere presence of an aneurysm is not always life-threatening, an aneurysm can cause a range of health problems, such ...

But when the location of the aneurysm is close to the branch vessel 31, such as Figure 7 As shown, if the artery is resected and artificial blood vessels are installed, the branch vessels will be blocked

In the prior art, there are also cases of using biological patches for extraluminal remodeling of blood vessels. However, after extraluminal remodeling of the biological patches used now, it is necessary to bind the biological patches on the outer surface of the blood vessels with sutures. It is in line contact with the outer surface of the blood vessel. If the force is too large, the blood vessel will be cut. If the force is too small, the bio-patch will be too loose, and the effect of vascular remodeling will not be achieved.
