Implantable device to provide electrical stimulation of cervical Vagus nerves for Treatment of chronic cardiac dysfunction with limited adjustment

摘要

Implantable device (11) for the treatment of Chronic Heart Failure with limited adjustment,That includes: an implantable neurostimulator (12) enclosed in a hermetically sealed housing (21) comprising a PULSE GENERATOR configured to manage a terapu00e9uti stimulationAC Electrical Self Restoring Balance adjusted for cyclical Electrical Impulses through ContinuousIntermittent periodic and managed so that results in the creation and Propagation direction in both afferent and Efferent) of Action potentials in neuronal Fibers.Nden a cervical Vagus nerve (15, 16,61) of a patient (10) In alternate Cycles of continuous implementation of STimulation and inhibition of Stimuli (90); a cable of cervical Vagus nerve stimulation Therapy (13) connected elu00e9ctricameThe nte pulse generator and ends in a pair of helical electrodes (14) through which electrical stimulation therapy is administered to the patient's cervical Vagus nerve (151661); and a sensor Integrated Wireless Heart Rate (31) content within the casing (21) and configured to detect and record a patient's heart rate in response to (72)Therapeutic electrical stimulation, in which the pulse generator is configured, in addition,(a) to alter the therapeutic electrical stimulation in response to the detected Heart Rate, as detected by the sensor Wireless Heart Rate (31),That is outside of a Predetermined range of Heart rates acceptable stored on a recordable Memory (29) in the pulse generator or (b) activate an automatic estiBut in a set of Therapeutic electrical stimulation parameters stored in writable Memory (29) in the PULSE GENERATOR progressively during a fixed period of time.
