Patent number: 11547860Abstract: A medical device with closed-loop responsive stimulation may include techniques to mitigate the impact on the therapy output of noise coupled into the medical device. A medical device according to this disclosure may determine the presence of noise and alter the closed loop policy to provide the necessary therapy to the patient and avoid prolonged under stimulation caused by the noise. The medical device may continue therapy, while testing for noise. When the device determines the noise level no longer affects the output therapy, the device may return the closed loop policy to a no-noise mode of operation. The medical device may also include techniques to mitigate the impact of manual adjustment while the medical device is subject to noise or is responding to changes in the patient's physiological signals.Type: GrantFiled: September 30, 2020Date of Patent: January 10, 2023Assignee: MEDTRONIC, INC.Inventors: Scott A. Hareland, Kevin C. Johnson, Christopher M. Arnett, Reid K. Bornhoft

Patent number: 11534614Abstract: Devices, systems, and techniques for controlling charging power based on a cumulative thermal dose to a patient are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. An external charging device may calculate an estimated cumulative thermal dose delivered to the patient during charging over a predetermined period of time. Based on the estimated cumulative thermal dose, the external charging device may select a power level for subsequent charging of the rechargeable power source. In one example, the charging device may select a high power level when the cumulative thermal dose has not exceeded a thermal dose threshold and select a low power level when the cumulative thermal dose has exceeded the thermal dose threshold.Type: GrantFiled: May 20, 2020Date of Patent: December 27, 2022Assignee: Medtronic, Inc.Inventors: Kevin J.

Publication number: 20220266025Abstract: Devices, systems, and techniques for calibrating posture state definitions are described. In one example, a system includes a memory configured to store a plurality of posture state definitions defining a plurality of posture states. The system may also include processing circuitry configured to receive a request to update the plurality of posture state definitions, responsive to receiving the request, and obtain sensor data for one posture state of the plurality of posture states, wherein the sensor data generated while a patient is in the one posture state. The processing circuitry may also determine a difference between the sensor data and a posture state definition of the posture state definitions corresponding to the one posture state, update, based on the difference, the plurality of posture state definitions, and store the updated plurality of posture state definitions in the memory.Type: ApplicationFiled: February 24, 2021Publication date: August 25, 2022Inventors: Scott A.

Publication number: 20220271575Abstract: Devices, systems, and techniques are described to provide consistent power transfer from a power transmitting unit to power receiving unit. In an example of recharging an electrical energy storage device, e.g., a battery, consistent power transfer may result in consistent recharge durations. A system may include a training mode in which a user may change a location of the power transfer unit relative to the power receiving unit. The system may provide an output to the user with a relative for a consistent power transfer. In other examples, a power transfer system may include a learning algorithm that measures and stores the power transfer during power transfer for a number of sessions over time. The learning algorithm may provide an output to a user of a relative location and/or relative orientation of the power transfer unit and power receiving unit that provides a consistent power transfer.Type: ApplicationFiled: February 23, 2022Publication date: August 25, 2022Inventors: Andrew Thomas Fried, Charles M.
