DETECTION OF IMPLANTED WIRELESS ENERGY RECEIVING DEVICE

摘要

An apparatus for detecting a wireless energy receiving device (12) that is subcutaneously implanted in a patient (13) is provided to enable accurate positioning of a wireless energy transmission device (14) outside the patient's body for transmission of wireless energy to the implanted energy receiving device. The apparatus includes a magnetic device (15) that emits a local magnetic field, and a magnetic detector (17) that detects the local magnetic field. The magnetic device (15) is subcutaneously implanted in the patient at the implanted energy receiving device (12) and the magnetic detector (17) is movable externally along the patient's body to establish a position at the patient's skin (16) where the local magnetic field is detected by the magnetic detector. As a result, the wireless energy transmission device (14) can be put in the established position, in order to efficiently transmit wireless energy to the implanted energy receiving device.
