Abstract

The invention provides an interatrial septum puncturing assembly and an interatrial septum puncturing method. The interatrial septum puncturing assembly comprises a catheter sheath and an expansion tube, the expansion tube is arranged in the catheter sheath in an attaching and penetrating mode, and one end of the expansion tube is fixedly provided with multiple electrodes. According to the interatrial septum puncturing assembly and the interatrial septum puncturing method, due to the fact that one end of the expansion tube is fixedly provided with the electrodes, ablation puncturing can be performed, a tent shape cannot be formed in an ejecting mode when the expansion tube passes through the fossa ovalis myocardium, and safe and rapid puncturing is achieved; meanwhile, use of a puncture needle is omitted, therefore, the surgical operation steps are simplified, and not only is the operation time saved, but also the cost of the puncture needle is saved; in addition, the electrodes can be attached to the inner wall of a heart chamber to extract electrical signals in the heart chamber, the position of the fossa ovalis is accurately determined through the electrical signals, and the puncturing safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an atrial septal puncture assembly and an atrial septal puncture method. Background technique [0002] The human heart consists of a right ventricle, right atrium, left ventricle, and left atrium. The right atrium is in fluid communication with the superior and inferior vena cava. The tricuspid valve separates the right atrium from the right ventricle. The right atrium is separated from the left atrium by the interatrial septum. The left atrium is the most difficult to access during surgery, accessing the left atrium through the pulmonary veins is not possible, and access from the left ventricle is difficult, which may lead to difficulties in catheter positioning. Thus, the most common method used to access the left atrium is through the interatrial septal puncture. [0003] In 1959, Ross et al. reported the animal experimental study of atrial septal puncture, and in ...
