Neural stimulation devices and systems for treatment of chronic inflammation

A leadless, implantable microstimulator device, the device comprising:

• a hermetically sealed cylindrical capsule body;
• an electrode saddle extending from a first side of the capsule body, wherein the electrode saddle comprises a first concave region comprising a first electrode and a second concave region comprising a second electrode;
• a resonator within the sealed capsule body, the resonator comprising a coil and a capacitor configured to resonate at a predetermined frequency range;
• a battery within the sealed capsule body;
• and
• an electronic assembly within the sealed capsule body in electrical contact with the first and second electrodes;
• wherein the electronic assembly comprises a microcontroller configured to control the application of electrical energy to a nerve held against the electrode saddle by applying energy between the first electrode and the second electrode and to control charging of the battery by the resonator.
