Abstract
A system for treating chronic inflammation may include an implantable microstimulator, a wearable charger, and optionally an external controller. The implantable microstimulator may be implemented as a leadless neurostimulator implantable in communication with a cervical region of a vagus nerve. The microstimulator can address several types of stimulation including regular dose delivery. The wearable charger may be worn around the subject's neck to rapidly (<10 minutes per week) charge an implanted microstimulator. The external controller may be configured as a prescription pad that controls the dosing and activity of the microstimulator.
Claims19
A leadless, implantable microstimulator device for treating chronic inflammation, the device comprising:
- a hermetically sealed capsule body;
- at least two electrically conductive capsule regions, wherein each region electrically connects to an electrode for applying stimulation to a vagus nerve;
- a resonator within the sealed capsule body;
- a battery within the sealed capsule body;
- and
- an electronic assembly within the sealed capsule body, wherein the electronic assembly is connected to the capsule body by a suspension configured to absorb mechanical shock and make electrical contact;
- wherein the electronic assembly comprises power management circuitry configured to receive power from the resonator to charge the battery, and a microcontroller configured to control stimulation of the vagus nerve from the conductive capsule regions.
A leadless, implantable microstimulator device for treating chronic inflammation by stimulation of a cervical region of a vagus nerve, the device comprising:
- a hermetically sealed capsule body having two electrically conductive capsule end regions separated by a central non-conductive region, wherein the capsule body has a hemi-cylindrical nerve channel, further wherein each conductive region is configured to electrically connect to an electrode for applying stimulation to a vagus nerve within the nerve channel;
- a resonator, battery and electronic assembly within the sealed capsule body;
- and
- a spring suspension connecting the electronic assembly to the capsule body to absorb mechanical shock;
- wherein the electronic assembly comprises power management circuitry configured to receive power from the resonator to charge the battery, and a microcontroller configured to control stimulation of the vagus nerve from the conductive capsule regions.
