Problems solved by technology

However, if the case screening is carried out according to this standard, 1 / 4 of the cases will be excluded and cannot receive TAVR surgery
In addition, even if TAVR is performed in full accordance with this standard, coronary artery blockage may still occur in a small number of cases

Embodiment Construction

[0034] Such as figure 1 Shown is a schematic structural view of the first form of a preferred embodiment of the present invention. The coronary artery protection device is tubular with a grid structure and includes an isolation part 1 and a fixing part 2. The parts of the device can be connected by conventional connection methods, or can be made by integral molding.

[0035] In this embodiment, the isolating part 1 and the fixing part 2 are an integrated circular tube, and its first shape is similar to the letter L as shown in the figure. The round tube has a rhombus grid structure, and the isolating part 1 and the fixing part 2 to form a bent round angle α, the size of α is determined by the angle between the central axis of the isolation component 1 and the central axis of the fixed component 2, preferably 60° to 150°; the grid line ratio of the isolation component 1 The grid lines of the fixed part 2 are slightly thicker, which can provide greater support.

Abstract

The invention discloses a coronary artery protecting device which comprises an isolating part and a fixing part. The isolating part is used for isolating a potential obstacle from a coronary artery opening, and the fixing part is used for fixing the position of the isolating part. The device is provided with a grid structure, the grid structure is implanted into the joint portion of the ascending aorta and coronary artery through the peripheral arterial path, the grid structure is implanted before transcatheter aortic valve replacement, smoothness of blood flow in the coronary artery during the transcatheter aortic valve replacement operation and after the operation can be guaranteed, coronary occlusion complications is avoided, and therefore transcatheter aortic valve replacement can be achieved for an aortic valve disease patient whose ascending aorta root anatomical structure does not meet the current standard.

Description

technical field [0001] The invention relates to a coronary artery protection device, in particular to a coronary artery protection device for transcatheter arterial valve replacement. Background technique [0002] Transcatheter aortic valve replacement (TAVR, transcatheteraorticvalvereplacement) is a popular new technology for cardiovascular intervention. This technology is to send the interventional catheter through the peripheral artery, and deliver the compressed artificial heart valve to the aortic valve area through the interventional catheter. It is a minimally invasive way to insert an artificial heart valve to complete the implantation of the artificial valve and restore the function of the valve. The technique is less invasive than open-heart surgery, thus greatly reducing the risk of cardiac surgery and shortening postoperative recovery time for patients. It has become the first-line treatment for patients with aortic stenosis internationally. The prospect of TAVR...
