Abstract:
Systems, devices and methods allow inductive recharging of a power source located within or coupled to an implantable medical device while the device is implanted in a patient. The recharging system/device in some examples includes a first electrical coil and a second electrical coil configured to generate opposing magnetic fields forming a resultant magnetic field within a recharging envelope located between the coils. A third coil of the implantable medical device may be positioned within the recharging envelope so that the resultant magnetic field is imposed on the third coil, causing electrical energy to be induced in the third coil, the induced electrical energy used to recharge a power source of an implantable medical device coupled to the third coil, and/or to power operation of the implantable medical device.
