Abstract
A system and apparatus for providing an in-vivo assessment of relative movement of an implant that is positioned in a living being is provided that includes a first assembly and a second assembly that are positioned within the living being. The first assembly includes a passive electrical resonant circuit that is configured to be selectively electromagnetically coupled to an ex-vivo source of RF energy and, in response to the electromagnetic coupling, generates an output signal characterized by a frequency that is dependent upon a distance between the first assembly and the second assembly at the time of the electromagnetic coupling.

An apparatus for providing an in-vivo assessment of relative movement of an implant in a living being, the apparatus comprising:
- a first assembly positioned within the living being and comprising a passive electrical resonant circuit;
- and
- a second assembly positioned within the living being and spaced therefrom the first assembly;
- wherein the first assembly is configured to be selectively electromagnetically coupled to an ex-vivo source of RF energy and, in response to the electromagnetic coupling, to generate an output signal characterized by a frequency that is dependent upon a distance between the first assembly and the second assembly.
