Abstract

The invention discloses a conveying system for an atrial shunt. The conveying system comprises a conveying structure and a control structure for controlling the axial movement of the conveying structure, the conveying structure comprises a conveying sheathing canal and a pushing rod penetrating through the conveying sheathing canal; the control structure comprises a control part and a conduction part which are connected with each other; the far end of the conduction part is connected with the pushing rod, the control part is rotated to drive the conduction part to move, and then the conduction part drives the pushing rod to move along a channel formed by the conveying sheath tube. The loading, conveying and releasing functions of a traditional atrial shunt conveying device are integrated on one handle, the complexity of the device is reduced, operation is easy, and the receiving speed of a doctor to the device is increased. Finally, the control structure is divided into the first control part and the second control part, and the requirements for refinement and operation time saving in actual operation are flexibly met.

Description

technical field

[0001] The present invention relates to the technical field of medical devices, in particular to a delivery system for an atrial shunt. Background technique

[0002] Heart failure (HF) for short , resulting in cardiac circulatory disorder syndrome, which is manifested as pulmonary congestion and vena cava congestion in this disorder syndrome.

[0003] According to the location of heart failure, it can be divided into: (1) Left heart failure: refers to heart failure caused by left ventricular compensatory insufficiency, which is relatively common clinically and is characterized by pulmonary circulation congestion; (2) Right heart failure: simple Right heart failure is mainly seen in pulmonary heart disease and some congenital heart disease, and is mainly characterized by systemic congestion; (3) Whole heart failure: after left heart failure, the pulmonary artery pressure increases, which increases the load on the right heart. Right heart failure also occ...
