Example Embodiment

[0012] Example 1

[0013] The straight cylindrical part 3 of the present invention is 40 mm long and 28 mm in outer diameter. The long branch branch 4.1 has an outer diameter of 12mm and a length of 140mm. The short branch 4.2 has an outer diameter of 12mm and a length of 50mm. The internal iliac artery branch 7 is set on the long branch, which is 30mm in length and 8mm in outer diameter. Circular metal marks 5 are provided at the edges and bifurcations of the present invention.

Example Embodiment

[0014] Example 2

[0015] The present invention is provided with an extension branch 6, an outer diameter of 12 mm, and a length of 140 mm, and the extension branch is provided with an internal iliac artery branch 7, an outer diameter of 8 mm, and a length of 28 mm. The structure of the main body is the same as in Example 1.

Abstract

The invention relates to a novel cavity isolation graft of abdominal aorta-internal iliac artery, which consists of a metal wire stent (1) and tubular fiber fabric (2) fixed in the stent. The graft is divided into a straight cylinder part (3) and a furcation part (4); the first Z-shaped stent circle of the upper end of the straight cylinder is not covered by the fabric, and the lower end of the straight cylinder is the furcation part which is provided with a long branch (4.1) and a short branch (4.2); the positions of the two branches are corresponded to the two sides of an external iliac artery; a length-added branch (6) can be inserted into the short branch; relevant parts of the metal wire stent are provided with metal markers (5) so that the graft can be pushed to a lesion part precisely by a conveyor under X line; the graft is characterized in that the long branch (4.1) is provided with an internal iliac artery branch (7); the length-added branch (6) of the short branch can also be provided with an internal iliac artery branch. The graft has the advantages of simple structure, convenient operation, capability of effectively isolating the blood from the lesion vein sections of the abdominal aorta and (or) the external iliac artery and (or) the internal iliac artery, guaranteeing unblocked blood flow, eliminating hidden troubles of pelvic ischemia, and high surgical success rate.

Description

technical field [0001] The invention relates to the technical field of medical devices, and is a novel abdominal aorta-internal and external iliac artery intraluminal isolation graft. Background technique [0002] Abdominal aortic aneurysm is a partial cystic expansion of the vessel wall that gradually occurs due to arteriosclerosis and other factors. After the artery wall expands to a certain extent, it cannot withstand the impact of blood flow and suddenly ruptures, resulting in sudden death of the patient. In recent years, endovascular grafts have been increasingly used in the minimally invasive field for the treatment of aortic aneurysms. The vascular endograft is also called the vascular endoluminal isolation system. It is composed of a wire stent and a tubular fiber fabric fixed in the stent. The stent is equipped with a metal marker so that it can be accurately pushed to the lesion with a conveyor under X-ray. The stent is made of ultra-elastic fine alloy wires that ...
