Abstract

An implant is provided for closing passages in organs and defects. The implant has a primary structure, e.g. coil, of a resilient material, where the implant in an operational state, forms a secondary structure, e.g. coil, of greater diameter than that of the primary coil. The implant can be converted by a guide element from the shape of the secondary coil into a transporting state in which the implant adopts an elongate shape, and the implant once again assumes the operational state by removal of the guide element. In order to improve the success of treatment, it is proposed, for achieving a better securing of the implant in a larger passage of an organ, that the primary coil has areas of different transverse spring rate along its longitudinal extent. A set is furthermore proposed with an implant according to the invention, and a device for applying such an implant with a guide element.
