Methods and apparatuses (e.g., devices and systems) for
vagus nerve stimulation, including (but not limited to) sub-diaphragmatic
vagus nerve stimulation. In particular, the methods and apparatuses described herein may be used to stimulate the posterior sub-diaphragmatic
vagus nerve to treat
inflammation and / or inflammatory disorders. The implantable microstimulators described herein may be inductively charged and / or communicated with using the external charger. The
implant may include a receiving antenna wrapped around the battery and / or the housing of the microstimulator / microregulator and / or may include a high magnetic permeability material in order to serve as a
magnetic core for the antenna coil. Wearable inductive chargers / communication devices for inductively communicating with (including charging) an implanted microstimulator are described herein, which may include magnetically conductive material to enhance communication with an
implant, including sub-diaphragmatic implants. Also described herein are inductive chargers / communication devices, including belts, and pads (e.g., mattresses) able to recharge an implanted
neurostimulation device.
