Patent ID: 8668742

Claim:
A system comprising: a gate having a passageway and a primary coil formed from a number of first coil turns positioned so as to define a first reference plane; and an orthopaedic implant comprising: a platform having a bottom surface, a stem secured to the bottom surface of the platform and extending downwardly therefrom, a housing coupled to the stem having a chamber defined therein, and a secondary coil formed from a number of second coil turns in registry with each other, each second coil turn extending in a first direction parallel to the bottom surface of the platform to define a longitudinal axis of the secondary coil, each coil turn of the secondary coil being positioned in a second reference plane extending orthogonal to the longitudinal axis, wherein the secondary coil is positioned in the chamber of the housing of the orthopaedic implant such that the second reference plane is capable of being oriented substantially parallel with the first reference plane and the longitudinal axis is capable of being oriented substantially orthogonal to the first reference plane when the orthopaedic implant is implanted in a body of a patient and the patient is traveling through the passageway.
