Embodiment Construction

[0034] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] In one embodiment of the present invention, as Figure 1-5 As shown, a stent graft for abdominal aortic aneurysm is provided, including a main route stent and a secondary route stent respectively, preferably, both the main route stent and the secondary route stent are made of a memory alloy skeleton 9 and a film covering material, The memory alloy skeleton 9 is sewn on the outside or inside of the covering material. Optimally, the memory alloy skeleton 9 is set in a corrugated shape.

[0036] The main road support includes a first cylindrical part 1 and a second cylindrical part 2. The first cylindrical part 1 and the second cylindrical part 2 are integrally formed. Optimally, the upper edge of the main road support is provided with an inverted V-shaped second cylindrical part. The fixing framework 10, the second fixing framework ...

Abstract

The invention discloses an abdominal aortic aneurysm covered stent. The covered stent comprises a primary path stent and a secondary path stent which are respectively arranged. The primary path stentcomprises a first cylinder part and a second cylinder part. The first cylinder part and the second cylinder part are integrally formed. A separation part is arranged in the first cylinder part, and the first cylinder part is equally divided into two semi-cylindrical cavities by the separation part. The second cylinder part and the lower edge of one of the semi-cylindrical cavities are integrally formed. The secondary path stent comprises a round pipe part and semi-cylindrical pipe parts attached to the semi-cylindrical cavities, the semi-cylindrical pipe parts and the round pipe part are integrally formed, and hooks are arranged on the edges of the semi-cylindrical pipe parts and arranged on the sides close to the separation part. Two first fixing frameworks are arranged on the upper edgeof the first cylinder part. The covered stent can effectively solve the problems that an existing covered stent is prone to moving and falling off and an existing secondary path stent is not easy to install.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an abdominal aortic aneurysm covered stent. Background technique [0002] Abdominal aortic aneurysm is a common clinical vascular disease. If it is not treated in time, it will be life-threatening due to the instantaneous rupture of the aortic aneurysm. At present, the commonly used clinical treatment method is interventional therapy. The principle of this method is to pre-load the covered stent into the delivery device, intervene into the lesion of the abdominal aorta through the femoral artery, and monitor it under the monitoring of X-ray fluoroscopy equipment. , accurately release the stent-graft at the lesion site, and after the implantation of the stent-graft, it can effectively reduce the intramural pressure of the aorta at the lesion site, thereby avoiding rupture of blood vessels near the abdominal aortic aneurysm. [0003] Currently, in the industry, stent graft...
