Abstract

The embodiment of the invention provides an atrial septum blood flow channel creating device. The device comprises a clamping mechanism used for clamping and positioning the atrial septum from the two ends of the atrial septum; the cutting pipe can axially move relative to the clamping mechanism and is used for cutting off part of the interatrial septum from the interatrial septum clamped by the clamping mechanism, so that a blood flow channel is formed in the interatrial septum. Therefore, the blood flow of the interatrial septum can be kept smooth for a long time and an implant does not need to be arranged on the interatrial septum.

Description

Technical field [0001] The present invention relates to the field of medical devices, and in particular, to a room blockblafting flow channel creation device. Background technique [0002] Heart failure referred to as heart failure, refers to the abundance of intravenous angverly blood volume, causing blood deposition of intravenous system due to the obstacles of the heart contraction function and / or diastolic function, leading to blood deposition of venous system, insufficient blood perfusion, which in turn caused heart Circulating obstacle symptoms. [0003] Heart failure is a serious disease with a higher incidence and a fatal rate. According to the part of heart failure, it can be divided into left heart failure, right heart failure, and whole failure, according to the clinical manifestation of heart failure, it can be divided into shrinkage. Heart failure and diastolic heart failure, wherein DiStolic Heart Failure, DHF is about half of all heart failure patients. There are...
