Abstract: Devices, systems and methods for the treatment of chronic inflammatory disorders that include an implantable microstimulator and an external charger/controller wherein the microstimulator is configured to operate using closed-loop feedback. The feedback for the microstimulator can be electrical activity of the vagus nerve and/or heart sensed by the microstimulator. The feedback can be used to modulate the stimulation duration, intensity, frequency, on-time and off-time.

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 leadless and batteryless.

Abstract: Diagnostic screening tests that can be used to identify if a patient is a good candidates for an implantable vagus nerve stimulation device. One or more analyte, such as a cytokine or inflammatory molecule, can be measured from a blood sample taken prior to implantation of a vagus nerve stimulator to determine the patient's responsiveness to VNS for treatment of an inflammatory disorder.

Abstract: In one embodiment, a method includes determining a fleet-level objective for a vehicle associated with instructing the vehicle to travel a route according to route criteria based on the fleet-level objective. The method includes receiving a ride request from a ride requestor associated with ride criteria including a pick-up location and a drop-off location. The method includes determining that the ride requestor is a passenger for the vehicle to satisfy the fleet-level objective contingent on modifications to the ride criteria. The method includes providing incentives to the ride requestor contingent on acceptance of the modifications to the ride criteria. The method includes, after receiving the acceptance of the modifications to the ride criteria, modifying the ride criteria in accordance with the route criteria. The method includes instructing the vehicle to transport the ride requestor based on the modified ride criteria so as to fulfill the fleet-level objective.

Abstract: Systems, devices, and methods for using vagus nerve stimulation to treat demyelination disorders and/or disorder of the blood brain barrier are described. The vagus nerve stimulation therapy described herein is configured to reduce or prevent demyelination and/or promote remyelination to treat various disorders related to demyelination, such as multiple sclerosis. A low duty cycle stimulation protocol with a relatively short on-time and a relatively long off-time can be used.

Abstract: In particular embodiments, a computing system may determine a predicted amount of ride requests for a plurality of collectively-managed vehicles and determine an availability of the collectively-managed vehicles to satisfy the predicted amount of ride requests. Subsequent to determining that the availability fails to satisfy one or more predetermined criteria for servicing the predicted amount of ride requests, the system may determine status information associated with the collectively-managed vehicles and determine, based on at least the status information, one or more minimum services for servicing one or more vehicles among the plurality of collectively-managed vehicles at one or more service centers such that the availability satisfies the one or more predetermined criteria. The system may instruct the one or more vehicles that are to receive the one or more minimum services to travel to the one or more service centers to be serviced.

Abstract: Methods and apparatuses for stimulation of the vagus nerve to treat inflammation including adjusting the stimulation based on one or more metric sensitive to patient response. The one or more metrics may include heart rate variability, level of T regulatory cells, particularly memory T regulatory cells, temperature, etc. Stimulation may be provided through an implantable microstimulator.

Abstract: Described herein are methods and systems for using EEG recordings to improve vagus nerve stimulation (VNS) therapy. In particular, described herein are methods and systems for using EEG recordings to detect P300 and/or activation of the nucleus basalis and/or the locus coeruleus to determine the efficacy of VNS. The EEG recordings can be used to provide feedback control to help optimize stimulation parameters and to screen for patients that respond well to VNS therapy.

Abstract: A nerve cuff for establishing a nerve block on a nerve can have a cuff body with a channel for receiving a nerve, a reservoir for holding a drug, and an elongate opening slit extending the length of the cuff body that can be opened to provide access to the channel and can be closed to enclose the cuff body around the nerve. The nerve cuff can also include an electrode for detecting and measuring electrical signals generated by the nerve. A controller can be used to control delivery of the drug based on the electrical signals generated by the nerve.
