FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to cardiovascular surgery, and can be used for permanent anatomical and electrical isolation of the left atrial appendage (LAA) during surgical correction of atrial fibrillation to prevent thromboembolic stroke in patients with atrial fibrillation. The clamp for LAA isolation includes two tubular working parts located in parallel, connected on one side by an opening element, and on the other side by an opening and retention element, consisting of loops and a lavsan thread passed through them. The opening element is made in the form of a cylindrical compression spring installed on one side of the tubular working parts, and each of its ends is passed inside the tubular working part and attached to the opening and retention element on the other side.
EFFECT: invention enables complete isolation of the LAA base with subsequent endothelization of the isolation line from the side of the endocardial surface of the left atrium without signs of thrombosis and wall rupture in the area of the clip installation.
