ABSTRACT:
To bring about an improvement in comparison with known implants, in particular with regard to economical mass production, an implant for the closing of defect openings in the body of a human or animal is proposed, with a load-bearing structure which, in a first operating state (primary form), has a great ratio of length to transverse extent along an axis and, at least in a further operating state (secondary form), has a much smaller ratio of length to transverse extent along the axis, the load-bearing structure being capable of being reversibly transformed from the secondary form into the primary form by exertion of a force against elastic material forces, the secondary form assuming approximately the form of a double disc with a proximal disc element and a distal disc element for receiving the surroundings of the defect opening between the disc elements, and the load-bearing structure being formed essentially in one piece without joining connections, and a placement system, in particular for such an implant, is proposed, with a stretching element and at least one, preferably two, holding wires, the stretching element serving for interacting with a distal end of an implant and the holding wire or wires serving for interacting with a proximal end of an implant, the implant being capable of being transformed from a primary form into a secondary form and vice versa by relative movement of the holding wires in relation to the stretching element.
