Apparatus, system, and method for transcutaneously transferring energy
First Claim
1. An apparatus for transcutaneously transferring an amount of energy to an implantable orthopaedic device, the apparatus comprising a cylindrical bobbin and a primary coil wound around the cylindrical bobbin, the cylindrical bobbin having an aperture configured to receive a portion of a patient'"'"'s body, wherein the primary coil has a resonant frequency matched to a resonant frequency of a secondary coil spaced apart from the apparatus and adapted to be coupled to the implantable orthopaedic device.

Abstract
An apparatus for transcutaneously transferring an amount of energy to an implantable orthopaedic device includes a primary coil. The primary coil has a resonant frequency matched to a resonant frequency of a secondary coil, which may form part of the implantable orthopaedic device. The primary coil may have an aperture configured to receive a portion of a patient'"'"'s body or may include a substantially “C”-shaped core. A power circuit may be coupled with the primary coil to provide power to the coil. The apparatus may also include a wireless receiver, a measuring device, and/or a display.
