  • Publication number: 20240066299
    Abstract: The invention refers to a device for inhibiting the neural activity of a carotid sinus nerve (CSN) or carotid body of a subject, the device comprising: one or more transducers configured to apply a signal to the CSN or associated carotid body of the subject, optionally at least two such transducers; and a controller coupled to the one or more transducers, the controller controlling the signal to be applied by the one or more transducers, such that the signal inhibits the neural activity of the CSN or carotid body to produce a physiological response in the subject, wherein the physiological response is one or more of the group consisting of: an increase in insulin sensitivity in the subject, an increase in glucose tolerance in the subject, a decrease in (fasting) plasma glucose concentration in the subject, a reduction in subcutaneous fat content in the subject, and a reduction in obesity in the subject.

  • Publication number: 20220080208
    Abstract: A system (1) for electrically stimulating a nerve (3), the system comprising: a first stimulator (5) and a second stimulator (7) for electrically stimulating the nerve, the first stimulator and the second stimulator spaced apart from one another by a first distance; and a controller (9) arranged to: a) set a time interval as a function of the first distance and the speed of propagation of an action potential in the nerve; b) activate the first stimulator for a first stimulation period, thus inducing electrical activity in the nerve; and c) activate the second stimulator for a second stimulation period after the time interval has elapsed after the end of the first time period. Preferably, the time interval is a sum of the first time period and a buffer time period for allowing the nerve to recover from stimulation.
