Abstract

See full text

A left atrial appendage (LAA) closure (1) and a system (6) for delivering the LAA closure are disclosed. The LAA closure (1) includes supporting struts (11), wherein the supporting struts (11) are distributed peripherally around a first hub (10) and extend outward, the supporting strut (11) bifurcates at a first position (110) into a left branch (111) and a right branch (112). The left branch (111) of each supporting strut (11) and the right branch (112) of an adjacent supporting strut join each other at a second position (113) and extend distally to form a distal end. The LAA closure further includes a supporting rod (12) between adjacent supporting struts (11) which ensures stability, absence of irregular deformation and lateral slippage, of the LAA closure (1). With the supporting rods (12) between the adjacent supporting struts (11), the LAA closure (1) forms a dense mesh which imparts high overall strength of the LAA closure (1).
