Problems solved by technology

When the balloon expands the stent, it can completely block the left ventricular outflow tract, blocking blood flow, causing a sudden increase in left ventricular pressure, causing the balloon and stent to dislodge

Embodiment Construction

[0012] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0013] Such as figure 1 As shown, a three-leaf balloon for expanding the aortic valve stent with a valve includes a balloon 1, a catheter 2 and a joint 4, the balloon 1 is formed by connecting three single balloons through the sides, and the Three single balloons are distributed in a triangle, and there is a catheter 2 in the gap formed by the connection of the sides of the three single balloons. Lumen joint, one lumen of the...

Abstract

The invention relates to a three-leaf sacculus for expanding an aortic valve support with valves. The three-leaf sacculus comprises a sacculus body, a catheter and a connector. The sacculus body is formed by connecting the side faces of three individual sacculi. The catheter penetrates through a gap formed by the connection of the side faces of the three individual sacculi, and a guide wire penetrates through the catheter. The catheter stretches out of the sacculus body downwardly and is divided to form a two-cavity connector, wherein the guide wire penetrates through one cavity of the catheter, the other cavity of the catheter serves as an inflation tube, the inflation tube of the catheter is communicated with an air delivery connector, the air delivery connector is connected with an air source or a water source, and the air source or the water source is communicated with the sacculus body through the inflation tube. The three-leaf sacculus for expanding the aortic valve support with the valves has the advantages that when the three independent sacculi prop open the support, the gap is reserved between the sacculi, so that the left ventricular outflow tract cannot be blocked, the pressure of the left ventricle is mitigated obviously, and displacement of the sacculus for expanding the aortic valve support is reduced or avoided.

Description

technical field [0001] The invention belongs to the technical field of valve support for aortic valve implantation surgery, in particular to a three-leaf balloon used for expanding the aortic valve support with a valve. Background technique [0002] Aortic valve disease is a common heart disease that includes aortic valve stenosis and regurgitation. For severe aortic valve disease, surgical aortic valve replacement has historically been the only treatment option. In recent years, transcatheter aortic valve replacement (Transcatheteraorticvalveimplantation, TAVI) has become a new method for the treatment of severe aortic stenosis. Currently, there are two types of valve stents that are most widely used clinically: one is a balloon-expandable valve stent; the other is a self-expandable valve stent. [0003] The application of TAVI technology in aortic valve insufficiency is still immature. One of the reasons is that the calcification of the aortic valve is not obvious in pati...
