A device (1) for measuring the diameter of an intracardiac opening (2), having a hollow body (3) made from a metal-wire mesh is provided that has twisted individual bars that form the jacket of the discontinuous wall (5) of the hollow body (3) and form longitudinal stabilization between two elastically deformable metal-wire meshes (6) forming the end sides of the hollow body (3) and are deformable in a position of use by an edge (17) of the opening (2) in a contact region into the interior of the hollow body (3). Thus, with the device (1), the size of the opening (2) can be determined in that, in an X-ray or ultrasound image, the deformation of the individual bars (4) is comparable through the opening (2) with markings (19, 20) arranged on the hollow body (3) and/or on the device (1) adjacent to the hollow body (3). |
