Problems solved by technology

[0008] Therefore, the existing endovascular stents for ascending aortic dilation disease and aortic valve disease are limited by insufficient anchoring area, inability to synchronize multiple lesions, involving coronary arteries, and large activity of ascending aorta. Aortic stenosis or partially old, dissecting aneurysm with high tear opening of aortic dilatation, limited use

Embodiment 1

[0073] Such as figure 1 The ascending aortic aortic valve integrated intravascular stent shown has a stent with an aortic valve (1) at the proximal end, a connector (2) in the middle, and an aortic stent (3) at the distal end, wherein:

[0074] The inner side of the body distal end of the aortic valve stent (1) is suspended with an artificial valve;

[0075] The connecting piece (2) is a flexible connecting piece, which is composed of at least two mutually independent silk threads, and each thread can contain 1 or more mutually independent or intersecting silk threads, and the two ends of the silk thread are respectively connected with the aortic valve For the stent (1) and the aortic stent (3), each strand of silk thread does not intersect or connect with each other, and the connecting piece (2) is not covered with an artificial membrane. Such as figure 2 The connectors described in A, B, C, and D are composed of at least two flexible wires, which may be 2 strands, 3 stran...

Abstract

The invention relates to the technical field of medical devices, in particular to an ascending aortic valve integrated intravascular stent, the proximal end is a stent with an aortic valve (1), the middle is a connecting piece (2), and the distal end is an aortic stent (3), wherein: the proximal end of the body with the aortic valve stent is skirt-shaped, the distal end is covered with an artificial membrane and the inner side of the aortic valve is suspended; the connecting piece (2) is a flexible connecting piece , consisting of at least two mutually independent silk threads, each thread may contain 1 or more than 2 mutually independent or intersecting silk threads, and the two ends of the thread are respectively connected with the aortic valve stent (1) and the aortic stent (3) , each strand of silk does not cross or connect with each other, and is not covered with artificial coating.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ascending aortic aortic valve integrated vascular stent. Background technique [0002] Aortic valve disease refers to primary or secondary insufficiency or stenosis of the aortic valve, often accompanied by dilation of the ascending aorta and other lesions. The existing main treatment method is surgical operation, which requires extracorporeal circulation during the operation. The operation trauma is large, and the perioperative mortality rate is high. Most elderly patients cannot tolerate it. Although the transcatheter aortic valve implantation technology that has emerged in recent years can treat some patients with aortic stenosis, it cannot treat patients with ascending aortic disease and aortic insufficiency. [0003] Dilated disease of the ascending aorta includes ascending aortic dissection (Stanford type A aortic dissection) and ascending aortic aneurysm. For ...
