Document Type and Number:
Japanese Patent JP6529137
Kind Code:
B2
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). The present invention effectively restrains the relative position and relative movement between the supporting segments (222) through the thin film (300), thus avoiding twisting of the supporting segments (222) when the fixing bracket (200) is pushed out and released from a delivery sheath.
