Abstract
A system is operable to detect the orientation of an implant component. The system comprises an implantable component, an external component, and a logic component. The implantable component comprises a first coil operable to transmit a first signal having a phase. The external component comprises a second coil operable to transmit a second signal having a phase. The logic component is operable to compare the phase of the first signal with the phase of the second signal. The logic component is further configured to determine an orientation of the first coil relative to the second coil based on a comparison of the phase of the first signal with the phase of the second signal. The system may be used to determine the orientation of an injection port in an implanted gastric band system. The system may alternatively be used in a variety of other types of systems.
