Various method embodiments detect a concurrent therapy, where the concurrent therapy includes a plurality of therapy pulses. Detecting the concurrent therapy includes detecting at least one electrical pulse, extracting at least one characteristic from the at least one electrical pulse, comparing the at least one characteristic of the detected pulse to at least one characteristic of therapy pulses, and detecting that the concurrent therapy is being applied if the at least one characteristic of the detected pulse favorably compares to the at least one characteristic of the therapy pulses.

An embodiment of an implantable system configured to be implanted in a patient includes an accelerometer, a neural stimulator, and a controller. The neural stimulator is configured to deliver neural stimulation to a neural target. The controller is configured to use the accelerometer to detect laryngeal vibration or coughing, and is configured to deliver a programmed neural stimulation therapy using the neural stimulator and using detected laryngeal vibration or detected coughing as an input to the programmed neural stimulation therapy.

A neurostimulation system senses a signal indicative of a patient's physical state such as posture and/or activity level. In various embodiments, a stored value for each of stimulation parameters controlling delivery of neurostimulation is selected according to the patient's physical state. In various embodiments, values of the stimulation parameters are approximately optimized for each of a number of different physical states, and are stored for later selection.

Various neural stimulator embodiments comprise controller circuitry, neural stimulation output circuitry, sensor circuitry and a memory. The neural stimulation output circuitry is configured to deliver the neural stimulation. The controller circuitry is configured to control stimulation parameters of the neural stimulation delivered by the neural stimulation output circuitry. The sensor circuitry, including at least one sensor, is configured to sense a response to the neural stimulation. The controller is configured to communicate with the sensor circuitry. The memory has instructions stored therein, operable on by the controller circuitry. The instructions include instructions for delivering neural stimulation using the neural stimulation output circuitry, instructions for controlling a titration sweep wherein the titration sweep varies stimulation parameter values, and instructions for monitoring a response to the titration sweep and automatically selecting stimulation parameters that provide an efficacious neural stimulation and provide a desirable safety margin to prevent injury to neural tissue.

A neurostimulation system provides for capture verification and stimulation intensity adjustment to ensure effectiveness of vagus nerve stimulation in modulating one or more target functions in a patient. In various embodiments, stimulation is applied to the vagus nerve, and evoked responses are detected to verify that the stimulation captures the vagus nerve and to adjust one or more stimulation parameters that control the stimulation intensity.

An embodiment uses an accelerometer to sense heart sounds, and determines heart rate info nation using the sensed heart sounds. An embodiment uses an accelerometer to sense respiratory activity. An embodiment delivers a programmed neural stimulation therapy with a programmed duty cycle, where the programmed duty cycle includes a stimulation ON portion followed by a stimulation OFF portion. An electrode electrically connected to the implanted neural stimulation device is used to remotely detect cardiac activity. The remotely detected cardiac activity is used to detect heart rate information during the stimulation ON portion and to detect heart rate information during the stimulation OFF portion. The detected heart rate information and/or the detected respiration information are used to control a neural stimulation therapy performed by the neural stimulator device and/or are used to provide diagnostic information for the patient's condition.

Various embodiments provide a method performed by an IMD to deliver a therapy to a patient. In some embodiments of the method, the therapy is delivered to the patient, and a trigger that is controlled by the patient is detected by the IMD. The therapy is automatically interrupted in response to the detected trigger, and is automatically restored after a defined period after the detected trigger. In some embodiments of the method, a trigger that is controlled by the patient is detected. The therapy is automatically initiated in response to the detected trigger, and is automatically stopped after a defined period after the detected trigger.
