Embodiment Construction

[0048] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be noted that, in the field of interventional medical devices, the end of the medical device implanted in the human body or animal body that is closer to the operator is generally called the proximal end, and the end that is farther away from the operator is called the distal end. This principle defines the proximal and distal ends of any component of a medical device. The specific technical solutions in the following embodiments may be mutually applicable without departing from the technical principles of the present application.

[0049] see figure 1 , is a schematic diagram of the structural principle of the left atrial appendage occlusion device provided by the present invention. The left atrial appendage occlusion device 1 inclu...

Abstract

The invention discloses a left atrial appendage plugging device and system, and relates to the field of medical instruments, the left atrial appendage plugging device comprises: a first skeleton having a first conductive portion, the first conductive portion being used for transmitting first ablation energy to tissue; the second skeleton is provided with a second conductive part, the second conductive part is used for transmitting second ablation energy to the tissue, and the polarity of the first ablation energy is opposite to that of the second ablation energy; and the first insulating connecting piece is used for connecting the first framework and the second framework. By means of the left auricle plugging device and system, the operation difficulty of left auricle ablation and plugging one-stop treatment can be reduced, and the operation procedure is simplified.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a left atrial appendage occlusion device and system. Background technique [0002] Atrial fibrillation is the most common sustained cardiac arrhythmia, and the incidence of atrial fibrillation increases with age. Some data show that the incidence of atrial fibrillation in people over the age of 75 can reach 10%. In addition, the prevalence of atrial fibrillation is also closely related to coronary heart disease, hypertension and heart failure. [0003] In the heart tissue, the left atrial appendage is not only the most important part of atrial fibrillation thrombosis due to its special shape and structure, but also one of the key areas for its occurrence and maintenance. Some patients with atrial fibrillation can benefit from active left atrial appendage electrical isolation surgery. . [0004] "Radiofrequency ablation + left atrial appendage closure" one-stop treatment is one o...
