IMPLANTABLE MEDICAL DEVICE WITH A FLUX CONCENTRATOR AND A RECEIVING COIL DISPOSED ABOUT THE FLUX CONCENTRATOR

An implantable medical device (IMD) with a receiving coil for wireless power transfer. The receiving coil may be disposed about a flux concentrator located in a housing of the IMD. The flux concentrator may concentrate non-radiative near-field energy through the receiving coil. In some cases, the near-field energy may be captured and converted into electrical energy that may be used to recharge a rechargeable power source of the IMD.
