Left ventricular volume reduction device and left ventricular volume reduction system

Abstract

The invention discloses a left ventricular volume reduction device and a left ventricular volume reduction system. The left ventricular volume reduction device comprises a plugging disc and an adjusting disc which are connected. The plugging disc comprises a first net-shaped structure and a flow blocking film covering a far-end opening of the first net-shaped structure. The adjusting disc comprises a second net-shaped structure, the second net-shaped structure comprises a barrel-shaped structure located at the near end and a conical structure located at the far end, and the adjusting disc has a compressed state and an unfolded state. The adjusting part is arranged in the adjusting disc in a penetrating mode, the far end of the adjusting part is fixedly connected to the far end of the conical structure of the adjusting disc, and the near end of the adjusting part is freely suspended and penetrates through the near end of the barrel-shaped structure. The adjusting part pulls the far end of the conical structure so that the adjusting disc can be switched between the compressed state and the stretched state, and the state of the adjusting disc can be maintained after the near end of the adjusting part is fixed. Therefore, the height and the shape of the left ventricle volume reduction device in the left ventricle can be adjusted by controlling the adjusting piece, the left ventricle volume reduction effect is achieved, and the left ventricle is prevented from being damaged by the anchor thorns.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a left ventricular volume reduction device and a left ventricular volume reduction system. Background technique [0002] Heart failure is a common heart disease that causes a patient's heart to not provide enough blood flow to meet the body's needs. Studies have shown that after a heart attack, many patients develop an enlarged left ventricle, which reduces cardiac output, which in turn causes symptoms of heart failure such as shortness of breath. Among them, left ventricular volume reduction surgery is a therapeutic technique used to isolate the damaged myocardium, isolating the non-functioning part of the heart from the healthy, functional part, thereby reducing the total volume of the left ventricle, restoring its shape and Function. Especially for patients with uncoordinated ventricular wall motion or aneurysm formation after myocardial infarction, isolating the ven...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the technical problem that the left ventricular volume reduction device in the prior art is anchored on the ventricular wall through the anchor thorn, it is easy to cause damage to the ventricular tissue and the volume reduction of the left ventricle cannot be adjusted in real time after successful anchoring, The invention provides a left ventricular volume reduction device and a left ventricular volume reduction system
