Abstract

The present disclosure discloses an atrial shunt implantation instrument. The atrial shunt implantation instrument comprises a support and a flow adjusting part, wherein a first channel part is arranged in the support; the flow adjusting part is connected with the support, the flow adjusting part is provided with a second channel part, the second channel part coaxially communicates with the first channel part, and the second channel part has a contraction state and an unfolding state along the radial direction; in the contraction state, the inner diameter of the second channel part has a first preset value; and in the unfolding state, the inner diameter of the second channel part has a second preset value, wherein the first preset value is smaller than the second preset value.

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 ...
