SUBSTANCE: invention can be used to isolate the left atrial appendage when surgically correcting atrial fibrillation in isolation or in combination with valvular pathology. A clip for left atrial appendage isolation contains a lock and working parts that are connected on one side by a curved bridge. The lock is made in the form of a lavsan thread in loops made of non-magnetic stainless steel. The loops are pressed into the ends of the working parts of the titanium tubes. The tubes are provided with the first coating of elastic polymer having an outer diameter of 1.3-1.5 mm and wall thickness of 0.2-0.4 mm. The bridge is made in the form of a tube-pressed spring made of non-magnetic stainless steel. The spring in the form of an open ring is connected by its ends with parallel straight rods. The working parts and the bridge are provided with the second coating in the form of a knitted tube with a diameter of 4.5-5.5 mm. A 0.7-0.8 mm thick coating is knitted from a polyester thread.

EFFECT: reliable atraumatic block of the communication between the left atrium and its appendage with an adjustable effort, to exclude thrombosis which occurs as a result of poor isolation of the left atrial appendage.
