Title: EXTERNAL CHARGER FOR AN IMPLANTABLE MEDICAL DEVICE HAVING A CONDUCTIVE LAYER PRINTED OR DEPOSITED ON AN INSIDE HOUSING SURFACE
Abstract:
A charging system for an Implantable Medical Device (IMD) is disclosed having a charging coil and one or more sense coils. The charging coil and one or more sense coils are preferably housed in a charging coil assembly coupled to an electronics module by a cable. The charging coil is preferably a wire winding, while the one or more sense coils are preferably formed in a conductive layer printed or deposited on an inside surface of the charging coil assembly housing or on an insulative substrate in contact with the inside surface. The conductive layer may also form traces in the charging coil assembly to couple to various electronic components within the housing, including for example a tuning capacitor for the charging coil, and one or more temperature sensors.
