Abstract

The invention relates to the field of medical instruments, in particular to a stent valve. The stent valve comprises a valve body and a valve stent; the valve stent comprises a sealing section, a drainage section, a transition section, an assembly section and a control section; the sealing section, the drainage section, the transition section, the assembly section and the control section are connected in sequence; and the valve body is disposed inside the assembly section. Through the arrangement of the sealing section, the drainage section, the transition section and the assembly section, the valve body is fixed, the whole valve is controlled through the control section, control convenience is improved, operation errors can be reduced under a condition of small trauma, and finally a purpose of reducing complications is achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a stent valve. Background technique [0002] The tricuspid valve, the right atrioventricular valve, connects the right atrium and right ventricle of the heart. The tricuspid valve is like a "one-way valve", which ensures that the blood circulation flows from the right atrium to the right ventricle and passes through a certain flow. When the right ventricle of the heart contracts, the blood in the chamber is squeezed, the blood hits the valve, the tricuspid valve closes, and the blood does not flow into the right atrium. [0003] The pathophysiological changes of cardiac tricuspid regurgitation are mainly manifested in two aspects: one is that the reverse blood flow and pressure caused by tricuspid regurgitation lead to increased right ventricular load, right ventricular dysfunction, and then right atrium, ventricle enlargement, The tricuspid valve ring expands, and the tricuspid ...
