Problems solved by technology

[0009] The above-mentioned technology has the following defects: the implant used for atrial shunt leaves an instrument at the stoma, which easily leads to thrombosis, or the instrument falls off, forming an embolism
In addition, the channel closure loses the shunt effect due to the endothelial attachment can cause the opening of the device to be blocked
In addition, there is a high risk of cutting intracardiac tissue by mechanical or high-frequency electrocautery during the operation, such as loosening of the intraoperative grasping device during surgery or during recovery, which may cause the cut tissue to fall off and be damaged. embolism
In addition, if the grasping device becomes loose during the cutting process, other myocardial tissue can easily be damaged

Embodiment Construction

[0040]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] In the description of the present invention, the tissue between the left atrium and the right atrium of the present invention is called atrial septum, the "proximal end" refers to the end of the interatrial septum close to the heart, and the "distal end" refers to the end far away from the heart One end of the interatrial septum position. The axial direction refers to the direction of the central axis of the device, and the radial direction refers to the...

Abstract

The invention provides an atrial septostomy system with an improved ablation manner. The system includes an atrial septostomy device, an ostomy device control mechanism for controlling the atrial septostomy device, and a radio-frequency power supply; the atrial septostomy device comprises a supporting skeleton for supporting perforated holes in an atrial septum, the atrial septostomy device further includes an ablation member arranged on the supporting skeleton, and the radio-frequency power supply is electrically connected to the atrial septostomy device through the ostomy device control mechanism; and the ablation member includes a first electrode and a second electrode, one of the first electrode and the second electrode is electrically connected to the output end of the radio-frequencypower supply, and the other electrode is connected to the input end of the radio-frequency power supply to form a current loop for receiving energy of the radio-frequency power supply for ablation ofthe atrial septum. The invention also relates to the atrial septostomy device of the atrial septostomy system.

Description

technical field [0001] The present invention relates to the technical field of interventional medical devices, in particular to an atrial septostomy device with an improved ablation mode of percutaneous intervention, and an atrial septostomy system provided with the atrial septostomy device. Background technique [0002] 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 important cardiovascular diseases today. According to the location of heart failure, it can be divided into left heart failure, right heart failure and whole heart failure. [0003] Heart failure is a...
