Abstract: An implantable medical system includes an implantable medical device and a external charger. The implantable medical device includes a rechargeable power source, electronic components coupled to the rechargeable power source to deliver a therapy to or monitor a parameter of a patient, and a recharge system operably coupled to the rechargeable power source including a secondary coil to receive power via an inductive power transfer. The external charger includes a housing forming an internal compartment, recharger electronic components disposed on a printed circuit board assembly in the internal compartment, and a recharge coil assembly disposed within the internal compartment, the recharge coil assembly including a recharge coil to provide power to the secondary coil via the inductive power transfer and a flux guide having a ferrite sheet disposed between the recharge coil and the printed circuit board assembly.
