Thoracic aortic aneurysm coated stent and thoracic aortic aneurysm minimally invasive treatment system

Abstract

The invention discloses a thoracic aortic aneurysm coated stent which comprises a metal stent and a polymer film which is sleeved on the external side of the metal stent. The metal stent comprises a laser cutting bare stent with one end located outside the polymer film, a laser cutting stent and a heat treatment stent; the laser cutting stent and the heat treatment stent are located inside the polymer film; the metal stent is in a waved structure; an overlapping part of the metal stent and the polymer film is in suture connection with the polymer film; and one end of the laser cutting bare stent, which is located on the external of the polymer film, is provided with a plurality of hanging rings which are used for connecting with a conveying system. According to the thoracic aortic aneurysm coated stent, a minimally invasive way can be employed to treat a thoracic aortic aneurysm to enable an aneurysm cavity and a parent artery lumen to be immediately isolated to repair lesion blood vessels. The invention also discloses a thoracic aortic aneurysm minimally invasive treatment system with the thoracic aortic aneurysm coated stent.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, relates to a thoracic aortic aneurysm covered stent and a minimally invasive treatment system for a thoracic aortic aneurysm. Background technique [0002] A thoracic aortic aneurysm is a blood-filled bump or swollen bubble within the running thoracic aorta. Over time, this swollen area can weaken, and even the force of normal blood pressure can rupture it, a bleb rupture that can be fatal. In the United States, more than 100,000 people suffer from aneurysm disease every year, and about 15,000 people die from it every year. Once an aneurysm ruptures, the survival rate is only 15%. There are 21,000 new cases every year, of which 60% are men and 40% are women. In my country, with the continuous improvement of people's living standards and population aging, the incidence of aortic aneurysm has been increasing year by year.

Problems solved by technology

[0003] For thoracic aortic aneurysm disease, the traditional treatment method is to resect the aneurysm and reconstruct the aortic vessel. Although it is effective, the surgical trauma is large, especially for elderly patients with heart, brain, lung, kidney and other important organ diseases , the operative mortality rate exceeds 20%, and the operative mortality rate is higher in elderly patients with multiple diseases, reaching more than 60%.
