Abstract: Far field telemetry communications are conducted during recharge sessions between an external device and an implantable medical device. The two devices may not have been previously paired together for far field telemetry and may have been paired with other devices for far field telemetry during previous recharge sessions and/or programming sessions. Embodiments provide for temporary bonding of the two devices for far field telemetry during the recharge session. The implantable medical device of the recharge session may maintain a programming bond with an external device other than the external device conducting the recharge session. Safeguards against establishment of inadvertent programming sessions between the external device that has conducted a recharge session and implantable medical devices that may or may not be bonded to that external device are provided.

Abstract: This disclosure is directed to devices, systems, and techniques for controlling electrical stimulation. In some examples, a computing device includes a therapy-management application configured to assist a user to: capture a representative evoked compound action potential (ECAP) signal from a patient based; apply one or more filters to the representative ECAP signal to select one or more parameters of the representative ECAP signal; and control electrical stimulation therapy based at least in part on the one or more parameters.

Abstract: Devices, systems, and techniques for selecting a period for charging an implantable rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. A system may control a charging module to begin charging the rechargeable power source of the implantable medical device with a high power level. The system may then determine an estimated heat loss based on power initially delivered to the rechargeable power source when beginning the charging. Based on this estimated heat loss during the initial period of recharging, the system may select a boost period that includes a duration of time that the rechargeable power source is charged with the high power level.

Abstract: 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.

Abstract: 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.

Abstract: 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.
