Left ventricular isolation system, left ventricular isolation device and conveying device thereof

Abstract

The invention provides a left ventricular isolation system, a left ventricular isolation device and a conveying device thereof. The left ventricular isolation device comprises a main body stent; the conveying device comprises a push mechanism and a recovery mechanism; the main body stent comprises a stent main body and first and second connecting parts; the stent main body comprises a first proximal end and a first distal end; the first connecting part is arranged at the first distal end; the plurality of second connecting parts are arranged at the first proximal end; the push mechanism comprises a third connecting part which is matched with the first connecting part, so that detachable connection between the push mechanism and the main body stent is achieved; the recovery mechanism is provided with fourth connecting parts which are matched with the second connecting parts, so that detachable connection between the recovery mechanism and the main body stent is achieved; and via the push mechanism and the recovery mechanism, the stent main body is driven to expand towards outer side or fold towards inner side, so that a function of repeatedly locating the left ventricular isolationdevice is achieved, and the accuracy of a release position of the left ventricular isolation device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a left ventricle isolation system, a left ventricle isolation device and a delivery device thereof. Background technique [0002] In recent years, the prevalence of heart failure has increased year by year, becoming a serious public disease problem. The prevalence rate of heart failure in my country is 0.9%, among which, coronary heart disease rose from 36.8% in 1980 to 45.6% in 2000, ranking first among various causes. After acute myocardial infarction, especially in patients with anterior wall myocardial infarction, about 20% to 50% of patients will develop heart failure. After acute anterior myocardial infarction, myocardial necrosis and subsequent scarring occur, leading to left ventricular remodeling, resulting in left ventricular enlargement and decreased left ventricular systolic function. [0003] Important hallmarks of ventricular remodeling are increased wall ...
