Abstract
A neurostimulation system comprises a sensor and a control system. The sensor is configured to detect a cardiac physiological measure of a patient. The control system is programmed to monitor, via the sensor, the cardiac physiological measure during the treatment. The control system is further programmed to detect a change in the cardiac physiological measure during the treatment. The control system is further programmed to determine, based on the detected change in the cardiac physiological measure, a first transition time in a duty cycle of a neurostimulation signal delivered to the patient where the neurostimulation signal transitions between a stimulation OFF period and a stimulation ON period.
Claims20
A neurostimulation system comprising:
- a sensor configured to detect a cardiac physiological measure of a patient;
- a control system programmed to:
- receive one or more stimulation timing parameters of a treatment;
- monitor, via the sensor, the cardiac physiological measure during the treatment;
- detect a first change and a second change in the cardiac physiological measure during the treatment;
- compare a time period between the first change and the second change with the one or more stimulation timing parameters;
- and
- determine, based on the comparison, a first transition time in a duty cycle of a neurostimulation signal delivered to the patient where the neurostimulation signal transitions between a stimulation OFF period and a stimulation ON period.
A method of delivering a neurostimulation signal to a patient from an implantable pulse generator, the method comprising:
- receiving, by a control system, one or more stimulation timing parameters of a treatment;
- delivering, by the implantable pulse generator, the neurostimulation signal to the patient via an electrode assembly, the neurostimulation signal having a duty cycle with a stimulation ON period and a stimulation OFF period;
- detecting, by a sensor, a cardiac physiological measure of the patient;
- monitoring, by the control system, the cardiac physiological measure during the treatment via the sensor;
- detecting, by the control system, a first change and a second change in the cardiac physiological measure during the treatment;
- comparing, by the control system, a time period between the first change and the second change with the one or more stimulation timing parameters;
- and
- determining, by the control system based on the comparison, a first transition time in the duty cycle where the neurostimulation signal transitions between the stimulation OFF period and the stimulation ON period.
One or more non-transitory computer-readable mediums comprising instructions executable by one or more processors to:
- receive one or more stimulation timing parameters of a treatment
- detect, via a sensor, a cardiac physiological measure of a patient;
- monitor, via the sensor, the cardiac physiological measure during the treatment
- detect a first change and a second change in the cardiac physiological measure during the treatment;
- compare a time period between the first change and the second change with the one or more stimulation timing parameters;
- and
- determine, based on the comparison, a first transition time in a duty cycle of a neurostimulation signal delivered to the patient where the neurostimulation signal transitions between a stimulation OFF period and a stimulation ON period.
