摘要：
Implantable closure device (1) for use in the human and / or animal body for the partial closure or closure of defective openings, cavities, organic pathways etc., with a support structure that in a first operating state (form primary) has a large relationship between length and transverse extension along an axis (63) and, in a second operating state (secondary form), has a smaller relationship between length and transverse extension along the axis (63), the support structure having a proximal section (20) and a distal section (30), characterized in that, in the primary form, the support structure is formed as a tubular element with two open ends, from of a single element (10) in the form of wire by cross-winding and / or twisting and / or braiding as a fabric and / or a non-woven fabric and / or a net, the proximal end of the proximal section (20) being ) or the extrem or distal of the distal section (30) of the tubular support structure of the primary form pulled or folded outwardly forming loops or loops (22, 32) in the outer marginal area (21, 31), said section being proximal and / or distal section (20, 30), in the secondary form, substantially flat in the form of a disk, while the other section is initially folded out in the form of a disk and then again bent inwards, being made in the area of the passage opening in such a way that it delimits an interior space (27).Dispositivo de cierre implantable (1) para el uso en el cuerpo humano y/o animal para el cierre o el cierre parcial de aberturas defectuosas, cavidades, vías orgánicas etc., con una estructura de soporte que en un primer estado de funcionamiento (forma primaria) presenta una relación grande entre la longitud y la extensión transversal a lo largo de un eje (63) y que, en un segundo estado de funcionamiento (forma secundaria), presenta una relación más pequeña entre la longitud y la extensión transversal a lo largo del eje (63), presentando la estructura de soporte una sección proximal (20) y una sec
