The device (1) has a hollow body (3) exhibiting an elastic wall (5) and inserted into an intracardiac opening (2), where the body expands perpendicular to an insertion direction. Two transparent markings (20) are arranged at a predetermined distance to each other, where the distance is compared with a molding of the body caused by an edge (17) of the opening. The body is permeable to liquid and is formed as a metal cage. The body is arranged discontinuous in a middle region between end sides, where the discontinuity is bridged by individual bars (4). Each bar is formed by two twisted wires. |
