Claim:
1. A passive ossicular prosthesis designed to replace or bridge at least one component of a human ossicular chain, comprising: a sound-conducting prosthesis body with a first coupling element designed in a form of a bight at one end and a second coupling element at another end; wherein the bight is made of a strip-shaped metallic material, is partially open toward an outside via a gap-type opening, is configured to enclose at least one of: the at least one component of the human ossicular chain, an actuator end piece for mechanical connection to the long process of incus, the manubrium of malleus, and an elongated actuator end piece of an active hearing aid, post-operatively encloses at least one of: the long process of incus, the manubrium of malleus and the actuator end piece in a non-positive manner and, intraoperatively is deformable using crimping tongs in the middle ear for fixation and permanent attachment of the first coupling element to at least one of: the long process of incus, the manubrium of malleus, or the actuator end piece; wherein the second coupling element is configured for mechanical connection to a further component or parts of a component of the ossicular chain or directly to the inner ear; and wherein the bight made of strip-shaped metallic material comprises a plurality of elongated perforations, longitudinal axes of which are configured to extend, in an implanted state of the ossicular prosthesis, along a curved trajectory at a right angle or at a slant relative to an axis that is parallel to at least one of: a longitudinal axis of the long process of incus, the manubrium of malleus or the actuator end piece.
