SYSTEM, APPARATUS, AND METHOD FOR IN-VIVO ASSESSMENT OF RELATIVE POSITION OF AN IMPLANT
First Claim
1. A method for providing an in-vivo assessment of relative movement of an implant in a living being, the method comprising:
- positioning a first assembly comprising a passive electrical resonant circuit within the living being; and
positioning a second assembly within the living being spaced from the first assembly;
selectively electromagnetically coupling the first assembly to an ex-vivo source of RF energy; and
generating an output signal from the first assembly, in response to the electromagnetic coupling, characterized by a frequency that is dependent upon a distance between the first assembly and the second assembly.

Abstract
A method for providing an in-vivo assessment of relative movement of an implant that is positioned in a living being is provided that comprises a first assembly and a second assembly that are positioned within the living being. The first assembly comprises 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.
