A kit of parts and method for the control of a delivery of an electric or electromagnetic pulse to a vagus nerve by an implanted stimulating device is provided. The kit of parts includes an implantable stimulating device (10) that includes a cuff electrode/optrode for being coupled to a vagus nerve (Vn) of a patient to be treated, and an encapsulation unit (50) suitable for being subcutaneously implanted at a location separated from the vagus nerve coupling unit (60), and enclosing an energy pulse generator (51s), for delivering electrical or optical energy pulses, and coupled to the cuff electrode/optrode by one or more electrical conductors (41e) and/or optical fibres (41f), an external controller device (100) of the kit includes laryngeal electrodes (161) suitable for being coupled to a laryngeal region (Lx) of a patient for measuring a laryngeal electrical activity at the laryngeal region, the laryngeal electrodes being coupled to an external control unit (150). The unit includes a setting unit (151) for entering control pulse parameters of a control energy pulse an external emitter (153e) configured for sending a signal to the implanted controller (54) to deliver to the cuff electrode/optrode one or more control energy pulses defined by the control pulse parameters entered in the setting unit, and a visual (155) or acoustic (157) display indicative of the intensity of the laryngeal electrical activity.

The present disclosure relates to a peripheral nerve electrode array that includes a first, second and third pair of electrodes spaced from each other along a longitudinal axis of the electrode array, the second pair of electrodes being located between the first and third pairs of electrodes. The present disclosure further relates to method for treating or preventing a chronic inflammatory condition in a human subject in need thereof, comprising providing to the human subject a therapeutically effective electrical stimulation of the anterior central abdominal vagus nerve or the posterior central abdominal vagus nerve, wherein the electrical stimulation is provided through two or more previously implanted electrodes at a site below the cardiac branches and above the hepatic-celiac branches of the nerve; and whereby the chronic inflammatory condition is prevented or treated in the human subject. In addition, the present disclosure relates to a method for treating or preventing a chronic inflammatory condition in a human subject in need thereof.

An implantable assembly is described for acquisition of neuronal electrical signals at a selected location which propagate along at least one nerve fiber contained in a nerve fiber bundle, as well as for selective electrical stimulation of the at least one nerve fiber, having: an implantable electrode assembly (E) which is disposed on a biocompatible support substrate which can be positioned around the nerve fiber bundle in a cuff, which has a cylindrical support substrate surface (i) which in the implanted condition is orientated facing the nerve fiber bundle, on which a first electrode assembly for locationally selective acquisition of the neuronal electrical signals and selective electrical stimulation of the at least one nerve fiber, and on which a second electrode assembly is disposed to record an ECG signal, and an analysis and control unit (A/S) which can be electrically conductively connected or is connected to the implantable electrode assembly (E), in which the locationally selective acquired neuronal electrical signals as well as the ECG signal can be analyzed in a time-resolved manner such that a neuronal time signal correlated with a physiological parameter, such as blood pressure, can be derived.

Systems and methods for treating a patient with dyspnea are disclosed. A method in accordance with a particular embodiment includes identifying the patient as suffering from dyspnea, and, based at least in part on identifying the patient as suffering from dyspnea, implanting an electrical signal delivery element within the patient in signal communication with an afferent neural pathway of a carotid body chemoreceptor. The method can further include at least reducing dyspneic sensations in the patient by directing an electrical signal from the electrical signal delivery element to the neural pathway to at least partially block afferent signals from the chemoreceptor.
