System and method for locating an internal device in a closed system
ActiveUS20070027505A1Eliminate the risk of infectionLess powerElectrotherapySurgeryCarrier signalPeripheral
A system and method for locating an internal device separated by a boundary from and in wireless communication with an external device. External device includes an active emitter mechanism wherein a carrier signal is modulated by a location interrogation signal thereby generating an external RF power signal during transmission to the internal device. A secondary antenna of the internal device receives the external RF power signal and induces an RF power signal therein that is converted to a DC induced voltage signal. An indication signal proportional to the intensity of the DC induced voltage signal induced in the secondary antenna is produced by the external device. The process is repeated each time the user moves the external device to a new location proximate the patient's body until a maximum DC induced voltage signal measurement is ascertained representative of a specific area in which the internal device is located.
