Abstract
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.
