An implantable device (1) for use in a human and/or animal body for replacement of an organ valve, has an elongate main body (10) having a first end and a second end (11,12) provided with openings, and a membrane element (20) provided with at least one opening, said device (1) having in a first operating state (primary form) a large ratio of length to transverse extent along an axis, and in a second operating state (secondary form) a smaller ratio of length to transverse extent along an axis, said device being reversibly convertible from the secondary form into the primary form by application of force against elastic material forces, wherein at least one of the two ends (11,12) of the main body (10) has an outwardly protruding anchoring portion (13,14) for anchoring the device (1) in the organ and/or a vessel. The invention refers also to a method for producing such implantable device (1). |
