Abstract

The invention discloses an atrial shunt device. The atrial shunt device comprises a storage tube, a supporting tube and a puncture shunt part, wherein a containing space is formed in the storage tube; the supporting tube is arranged in the containing space; the first end of the puncture shunt part is detachably connected with the supporting tube, and a spinal part is arranged at the second end of the puncture shunt part and is configured to be used for puncturing the atrial wall; and the puncture shunt part can move in the axial direction of the storage tube and has a contraction state located in the containing space and an expansion state located outside the containing space, and under the condition that the puncture shunt part is in the expansion state, the puncture shunt part is configured to be fixed to the atrial wall.

Description

technical field [0001] The present disclosure relates to the technical field of medical devices, and more specifically, to an atrial shunt device. Background technique [0002] In recent years, the treatment of heart disease has made great progress, but heart failure, one of the final outcomes of all heart diseases, has always threatened human health. Heart failure (heart failure for short), is a complex clinical syndrome of impaired ventricular filling or ejection due to any structural or functional abnormality of the heart, the main clinical manifestations of which are dyspnea and fatigue (limited exercise tolerance), and Fluid retention (pulmonary congestion and peripheral edema). Heart failure is the severe and terminal stage of various heart diseases, with a high incidence rate, and is one of the most serious cardiovascular diseases today. According to the location of heart failure, it can be divided into left heart failure, right heart failure and whole heart failure...
