Abstract

An implantable medical device may include a case which houses components of the implantable medical device. The implantable medical device may include an inductive coil coupled to a rechargeable battery. The inductive coil may be operative to inductively couple to an external coil and to transfer energy from the external coil to the rechargeable battery to recharge the rechargeable battery. The implantable medical device may include a cutout formed in the case of the implantable medical device and filled with a dielectric material. The cutout may be operative to reduce eddy currents in the case during recharge of the rechargeable battery. The implantable medical device may include a slot antenna disposed within the case. The slot antenna may be operative to communicate with an external device through the cutout in the case.
