First Claim
1. A system for using at least one electrode to deliver vagal nerve stimulation therapy to vagus nerve in a patient, comprising:
- an implantable device configured to be implanted in the patient, comprising;
stimulation circuitry configured to use the at least one electrode to deliver electrical stimulation to the vagus nerve;
memory including sets of programmed instructions stored therein to operate the device to deliver the vagal nerve stimulation in at least two different operating modes, wherein the implantable device is configured to change operating modes in response to an external signal, each of the at least two different operating modes is used to deliver vagal nerve stimulation therapy, and the sets of programmed instructions are concurrently in the memory and include different sets of programmed instructions to operate the device to deliver the vagal nerve stimulation therapy; and
a controller connected to the memory and the stimulation circuitry to control the stimulation circuitry, the controller configured to control delivery of the electrical stimulation for the neural stimulation therapy including change adjustable parameters to control delivery of the electrical stimulation for the neural stimulation therapy, the controller configured to execute the programmed instructions in the memory to operate the device to deliver the vagal nerve stimulation therapy in the at least two operating modes, the controller configured to receive the external signal transmitted from an external device external to the patient and respond to the received external signal by changing from executing one set of programmed instructions to operate the device to deliver the vagal nerve stimulation therapy in one of the operating modes to executing another, different set of programmed instructions to operate the device to deliver the vagal nerve stimulation therapy in another one of the operating modes.
