HYSTERESIS COMPENSATION FOR DETECTION OF ECAPS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240050753 titled 'HYSTERESIS COMPENSATION FOR DETECTION OF ECAPS
Simplified Explanation
The patent application describes systems, devices, and techniques for adjusting electrical stimulation based on detected evoked compound action potentials (ECAPs).
- The medical device includes processing circuitry that controls stimulation circuitry to deliver a first electrical stimulation pulse and sensing circuitry to detect an ECAP signal after the delivery of the first pulse.
- The processing circuitry determines a characteristic value of the ECAP signal and an ECAP differential value that indicates whether the characteristic value is greater than or less than a selected ECAP characteristic value.
- Based on the ECAP differential value, the processing circuitry determines a gain value and a parameter value that defines a second electrical stimulation pulse.
- The stimulation circuitry is then controlled to deliver the second electrical stimulation pulse according to the parameter value.
Potential applications of this technology:
- Medical devices for electrical stimulation therapy, such as cochlear implants, deep brain stimulators, or spinal cord stimulators, could benefit from the ability to adjust stimulation based on detected ECAPs.
- This technology could be used in neuroprosthetic devices to improve the effectiveness and customization of electrical stimulation for patients with neurological disorders.
Problems solved by this technology:
- Adjusting electrical stimulation based on detected ECAPs allows for more precise and personalized therapy, as it takes into account the individual's response to the stimulation.
- By dynamically adjusting the stimulation parameters, this technology can help optimize the therapeutic effects and minimize potential side effects.
Benefits of this technology:
- Improved therapy outcomes: By adjusting stimulation based on detected ECAPs, the therapy can be tailored to the individual's specific needs and response, potentially leading to better treatment outcomes.
- Enhanced patient comfort: The ability to optimize stimulation parameters can help minimize discomfort or unwanted side effects, improving the overall patient experience.
- Increased device longevity: By delivering stimulation pulses based on the parameter values determined from ECAPs, the device can operate more efficiently, potentially extending its battery life or reducing power consumption.
Original Abstract Submitted
systems, devices, and techniques are described for adjusting electrical stimulation based on detected ecaps. in one example, a medical device includes processing circuitry configured to control stimulation circuitry to deliver a first electrical stimulation pulse and sensing circuitry to detect, after delivery of the first electrical stimulation pulse, an ecap signal. the processing circuitry may be configured to determine a characteristic value of the ecap signal, determine an ecap differential value that indicates whether the characteristic value of the ecap signal is one of greater than a selected ecap characteristic value or less than the selected ecap characteristic value, determine, based on the ecap differential value, a gain value, determine, based on the gain value, a parameter value that at least partially defines a second electrical stimulation pulse, and control the stimulation circuitry to deliver the second electrical stimulation pulse according to the parameter value.
