Problems solved by technology

For patients with simple aortic valve regurgitation, most of them have no calcification, and the soft native valve cannot play a supporting role, which makes the artificial arterial valve system easily slide into the ventricle from the arterial blood vessel
Therefore, the current interventional aortic valve can hardly be used for the treatment of simple aortic regurgitation

Embodiment Construction

[0035] Such as figure 1 Shown is a schematic structural view of the first form of a preferred embodiment of the present invention. The artificial aortic valve ring system includes a valve ring support 1 at the distal end and an anchoring foot 2 at the proximal end, the valve ring support 1 is fixedly connected to the anchoring foot 2, and the connection method can be welding or wire tying, or It is made in one-piece molding (such as 3D printing).

[0036] Wherein, the annulus support 1 is tubular and has a rhombic grid (such as figure 2 shown), and the long axis of the rhombus is parallel to the axial direction of the valve annulus stent. The first part 11 of the valve ring stent is composed of a straight cylindrical second part 12, and the radial section of the first part 11 gradually decreases from the distal end to the proximal end, and the overall axial section of the annulus stent is similar to a "Y" shape In the axial length, the first part 11 accounts for about 3 / 4 ...

Abstract

The invention discloses an artificial aortic valve ring system, which is used for taking effects of supporting and fixing in trans-catheter aortic valve replacement on patients of aortic valve regurgitation without calcification. The system comprises a valve ring scaffold at distal end and anchoring legs at proximal end, wherein the valve ring scaffold is fixedly connected to the anchoring legs; the valve ring scaffold is of a tubular structure and has a gridding structure; the anchoring legs are arranged along the periphery of the valve ring scaffold and are embedded in a cavity structure on ascending aortic root so as to fix the system; and the system is capable of transforming between a first form of radial expansion and a second form of radial shrinkage. With the implantation of the system, the trans-catheter aortic valve replacement on patients of aortic valve regurgitation without calcification becomes possible.

Description

technical field [0001] The invention relates to an artificial aortic valve ring system, in particular to an artificial aortic valve ring system implanted through a peripheral arterial route. Background technique [0002] Transcatheter aortic valve replacement (TAVR, transcatheteraorticvalvereplacement) is a popular new technology for cardiovascular intervention. This technology is to send an interventional catheter through the peripheral artery, and deliver the compressed artificial heart valve to the aortic valve area through the interventional catheter to open it. In order to complete the implantation of the artificial valve and restore the function of the valve, it is a minimally invasive way to insert an artificial heart valve. The technique is less invasive than open-heart surgery, which greatly reduces the risks of heart surgery and patients' postoperative recovery time is also greatly shortened. [0003] However, this technique can only be used in patients with calci...
