    Abstract: The present invention relates to a device (D) for occluding atrial septal defect. Non-woven wires are introduced in one or more stages, with each stage interspaced with one or more braids and braided together with the wires from the woven centre and earlier stages to form the device (D). The transcatheter device (D) has two discs (101, 102) one a hub-less disc incorporating a woven central section on the left atrial side and the other disc on the right atrial side with a connecting neck (110) braided from wires. The device (D) has thrombogenic material in either discs (101, 102). A ridge (108) is configured on the periphery of either the left atrial disc or right atrial disc or both discs to improve structural stability of the device and provides enhanced elapsing force onto the septum reducing chances of migration.
