Hook connection type puncturable trans-catheter conveying atrial wall occluder device system

Abstract

The invention discloses a hook connection type puncturable trans-catheter conveying atrial wall occluder device system which comprises a occluder device and a conveying device used for conveying the occluder device, the occluder device comprises a left atrium side disc and a right atrium side disc, the left atrium side disc and the right atrium side disc are connected through a connecting waist part, a hole channel is formed in the center of the left atrium side disc and the center of the right atrium side disc in a penetrating mode, and a plurality of connecting pieces are arranged on the end face of the right atrium side disc around the hole channel; and the conveying device comprises a conveying sheathing canal and a conveying rope movably arranged in the conveying sheathing canal, one end of the conveying rope can extend out of one end of the conveying sheathing canal and is connected with a plurality of conveying connecting parts, the conveying connecting parts are detachably connected with the connecting pieces, and the conveying connecting parts are connected with the connecting pieces during conveying. The system is reliable in connection and accurate in release, a defect part can be safely and effectively blocked, meanwhile, an interatrial septum puncture area is reserved, and a space is reserved for possible interatrial septum puncture operation when needed in the future.

Description

technical field [0001] The invention relates to the field of cardiac atrial septal occluder, in particular to a hook-connected punctureable interatrial wall occluder system delivered through a catheter. Background technique [0002] With the development of population aging and the high incidence of hypertension, valvular disease and other diseases, the number of patients suffering from atrial fibrillation is increasing day by day, and the interventional treatment of atrial fibrillation, whether it is left atrial appendage occlusion or pulmonary vein isolation treatment, requires puncture of the atrial septum. Among these patients, a considerable number of patients with atrial defect have undergone atrial septal defect closure or patent foramen ovale closure. Currently, the commonly used clinical occluder is the central rivet type. There is a dense metal mesh, and there are fixed steel rings and connecting riveting in the center of the occluder. For the atrial septum that has...

Problems solved by technology

[0002] With the development of the aging population and the high incidence of hypertension, valvular disease and other diseases, the number of patients suffering from atrial fibrillation is increasing day by day, and the interventional treatment of atrial fibrillation, whether it is left atrial appendage occlusion or pulmonary vein isolation treatment, requires puncture of the atrial septum. Among these patients, a considerable number of patients with atrial defect have undergone atrial septal defect closure or patent foramen ovale closure. Currently, the commonly used clinical occluder is the central rivet type. There is a dense metal mesh, and there are fixed steel rings and connecting riveting in the center of the occluder. For the atrial septum that has been implanted with the occluder, it is difficult to perform atrial septal puncture. If the puncture of the atrial septum is unsuccessful, further pulmonary veins cannot be performed. Isolation and left atrial appendage occlusion, etc., so in order to allow patients implanted with an atrial septal occlusion device to perform atrial septal puncture smoothly, a new atrial septal occluder is needed
