Abstract

The present disclosure discloses an atrial shunt implanting device. The atrial shunt implanting device comprises a support; the support is provided with a first end, a middle channel part and a second end which are sequentially arranged in the first direction, and the middle channel part is connected with the first end and the second end; the middle channel part has a contraction state and an expansion state in the second direction; in the contraction state, the middle channel part has a first inner diameter in the middle position of the first direction; in the expansion state, the middle channel part has a second inner diameter in the middle position of the first direction; the second inner diameter is larger than the first inner diameter; and the minimum inner diameter of the first end and the minimum inner diameter of the second end are both larger than the first inner diameter and smaller than the second inner diameter.

Description

technical field [0001] The present disclosure relates to the technical field of medical devices, and more specifically, to an atrial shunt implantation 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 ...
