Abstract
In one embodiment, an implantable medical device comprises: a rechargeable battery for powering the implantable medical device; an antenna for receiving RF power; and circuitry for charging the rechargeable battery using power received via the antenna, wherein the circuitry for charging comprises control circuitry that causes the circuitry for charging to recharge the rechargeable battery using multiple current levels applied in succession, and wherein the circuitry for charging switches from at least one of the current levels to another current level when a charging voltage of the rechargeable battery reaches a threshold value that is varied by the control circuitry over a lifespan of the rechargeable battery.
