Plugging device used in tubular cavity

Abstract

The invention discloses a plugging device used in a tubular cavity. The plugging device is characterized by comprising a plugging end (1), a transition section (2) and an open end (3), wherein the plugging end (1) is used for plugging a neoplasia neck port in the tubular cavity, and the transition section (2) is connected with the plugging end (1) and the open end (3) and is located in the blood vessel cavity. After the plugging device used in the tubular cavity is implanted in the blood vessel, the plugging device can be stably arranged at the crotch of the blood vessels or the tail section of the corresponding blood vessel, is used for plugging the neoplasia neck port in the cavity, can directly plug an ending arterial aneurysm neck port and can also assist embolization of a spring ring of the ending wide-necked arterial aneurysm neck port after being put in.

Description

technical field [0001] The present application relates to the technical field of intravascular interventional therapy, in particular to an intraluminal occlusion device. Background technique [0002] Luminal walls, especially arterial walls, may develop pathologically dilated regions known as aneurysms. Aneurysm is a common vascular disease, which is the result of expansion or bulging of the arterial wall due to lesion or injury of the arterial wall. The bifurcations of human blood vessels and large-angle bends of blood vessels are one of the prone sites of aneurysms. The aneurysm wall is extremely thin, and the blood flow directly punches inside the aneurysm. If no intervention is performed, the aneurysm will continue to expand. There is a danger of rupture, and once the aneurysm ruptures, it will pose a great threat to human life. According to the location of the aneurysm, it can be divided into peripheral aneurysm, abdominal aortic aneurysm, thoracic aortic aneurysm, vi...

Problems solved by technology

Second, the coil is easy to fall off from the aneurysm to the parent artery, resulting in occlusion of the normal blood supply artery and the formation of ischemic stroke

For this type of aneurysm, the Y-shaped double stent-assisted embolization technique has been tried, but there are defects: first, the microcatheter passes through the first stent mesh and enters the other artery sometimes cannot be realized; second, when the first stent mesh For open-loop stents with large holes, the segment where the second stent passes through the mesh of the first stent is not fully opened or even cannot be opened
