Abstract
An implantable medical device including a data communication device that includes a device that alters an oscillatory electric field imposed on body tissue surrounding the implantable device. The device that alters an oscillatory electric field modulates an impedance of a conductive medium surrounding the implantable device when the implantable device is within an oscillatory electric field. The device that alters an oscillatory electric field includes a device that generates an oscillatory electric field that is phase-synchronized with an oscillatory electric field imposed on a conductive medium surrounding the implantable device.
