Abstract: The present invention relates to a left atrial appendage occluder having a sealing disc and a fixing bracket which is connected to the sealing disc and located at one side of the sealing disc; the fixing bracket comprising a connecting portion connected to the sealing disc, and a plurality of supports. After radiating out distally from the connecting portion, the plurality of supports are bent to extend proximally to form a plurality of spaced suspended supporting segments. The left atrial appendage occluder further includes a thin film, with all the supports being connected through the thin film.

Abstract: A method for implanting an interventional medical device, including the following steps: delivering the distal end of the puncture needle into the right atrium via the inferior vena cava; locating the puncture site on atrial septum under X-ray fluoroscopy in a first perspective angle and a second perspective angle, and puncturing the atrial septum by the puncture needle through the puncture site; delivering the medical device to the left atrial appendage or left atrium for release under X-ray fluoroscopy in a first perspective angle. The implanting method of the disclosure does not require the use of a TEE device during implementation and provides benefits of a simple operation, short operation time, and easy implementation conditions, while also be easy to promote and popularize.

Abstract: The present invention relates to a left atrial appendage occluder (10), comprising a sealing disc (100) and a fixing bracket (200) which is connected to the sealing disc (100) and located at one side of the sealing disc (100); the fixing bracket (200) comprising a connecting portion (210) connected to the sealing disc (100), and a plurality of supports (220); after radiating out distally from the connecting portion (210) and coordinating to form a recessed area (221), the plurality of supports (220) are bent to extend proximally to form a plurality of spaced suspended supporting segments (222), the supporting segment (222) being provided with at least one anchoring barb (223) facing the sealing disc (100). The left atrial appendage occluder (10) further comprises a thin film (300), all the supports (220) being connected in series through the thin film (300).
