Implantable neurostimulator for providing electrical stimulation of cervical vagus nerves for treatment of chronic cardiac dysfunction with bounded titration
First Claim
1. A system for providing electrical stimulation of cervical vagus nerves for treatment of chronic cardiac dysfunction with bounded titration, comprising:
- a patient-operable external controller configured to transmit a plurality of unique signals comprising a unique signal associated with an up-titration command; and
an implantable neurostimulator comprising;
a pulse generator configured to deliver electrical therapeutic stimulation tuned to restore autonomic balance through continuously-cycling, intermittent and periodic electrical pulses simultaneously delivered at an intensity that avoids acute physiological side effects and with an unchanging cycle not triggered by physiological markers in a manner that results in creation and propagation (in both afferent and efferent directions) of action potentials within neuronal fibers comprising a cervical vagus nerve of a patient through a pair of helical electrodes via an electrically coupled nerve stimulation therapy lead; and
a recordable memory storing an autotitration operating mode comprising a maximum stimulation intensity and configured to increase an intensity of the delivered electrical therapeutic stimulation up to a level not exceeding the maximum stimulation intensity upon receipt of the unique signal associated with the up-titration command.

Abstract
A system for providing electrical stimulation of cervical vagus nerves for treatment of chronic cardiac dysfunction with bounded titration is provided. The system includes a patient-operable external controller to transmit a plurality of unique signals. The system further includes an implantable neurostimulator, which includes a pulse generator to deliver electrical therapeutic stimulation tuned to restore autonomic balance through continuously-cycling, intermittent and periodic electrical pulses that result in creation and propagation (in both afferent and efferent directions) of action potentials within the cervical vagus nerve of a patient through a pair of helical electrodes via an electrically coupled nerve stimulation therapy lead. The neurostimulator also includes a recordable memory storing an autotitration operating mode that includes a maximum stimulation intensity and is configured to increase an intensity of the delivered electrical therapeutic stimulation up to a level not exceeding the maximum stimulation intensity upon receipt of one of the unique signals.
