The invention is about an occluder device which is used for treatment through transcatheter in order to occlude congenital heart defects, vascular abnormalities or left atrial appendage and about production process of the device. The device contains biocompatible wire cage made of either a memory metal, or an alloy, or a polymeric material. The device also contains a thread mesh retained to the wire cage and an artificial or natural acellular dermal matrix. The distal retention zone is designed as a hollow "whirling dervishs skirt", and can be circular, oval, triangular according to the type of defect it will occlude. The device may comprise a marker. This special designed device is lighter, and has lower metal loadings than its counterparts. The production process is simpler, and the dermal matrix it contains enables a faster recovery and high complete occlusion success rate. The devices for occluding the left atrial appendage have been designed for narrow or broad defects, and the surfaces of the proximal retention area facing the left atrium has been coated with biocompatible and antifibrin material so that its nickel-titanium alloy content cannot lead to new thrombus formation.Linvention concerne un dispositif dobturateur, qui est utilisé pour un traitement non-opératoire au moyen dun transcathéter au moyen dun blocage de malformations cardiaques congénitales, danomalies vasculaires ou de lappendice auriculaire gauche, et le procédé de production du dispositif. Le dispositif contient un treillis métallique biocompatible fait dun métal à mémoire ou dun alliage ou dun matériau polymère. Le dispositif contient également une maille de filet retenue sur le treillis métallique et une matrice dermique acellulaire artificielle ou naturelle. Une zone de retenue distale est conçue sous la forme « dune jupe de derviche tourneur», et elle peut avoir une forme circulaire, ovale, triangulaire ou de rayon en fonction du type de malformation quelle bloque, et les extrémités com
