AI Technical Summary
In cardiac valve surgery, the existing stents are uneven in circumferential deformation during expansion, resulting in severe deformation at the valve junction and almost non-deformation of other meshes, increasing the risk of coronary orifice obstruction.
A valve support base is designed, including a bracket, inner skirt, base, base skirt and sewing ring. The base is located under the bracket and can be sealed and connected. The bracket is grid-shaped and has arc-shaped connecting strips. The base is connected by triangular support blocks and wavy wire to ensure that the base can better support the bracket.
Through the design of arc-shaped connections and triangular support blocks, the base can support the stent more effectively, reducing the uneven deformation of the stent during diameter expansion, improving the protection and support effect of the valve, and reducing the risk of coronary orifice blockage.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cardiac membrane valves, in particular to a valve supporting base. Background Art
[0002] During heart valve surgery, the valve needs to be supported. Because the circumferential grids of the stent are different, the circumferential direction of the stent is not uniform when it is expanded. During the expansion process, the main deformation of the stent occurs at the valve connection, and the other grids are slightly deformed or not deformed. According to surgeons, the stent is generally aligned with the native leaflet, so that the other grids of the stent are aligned with the coronary artery ostium. If the stent is deformed and the other grids are not deformed, in addition to causing the stent to be in a trumpet-shaped state, the height of the other grids of the stent will not change after expansion and the openings of the other grids will not increase, which is bound to increase the risk of coronary artery ostium obstruction.
