Abstract: Systems, devices, and techniques are described for analyzing evoked compound action potentials (ECAP) signals to assess the effect of a delivered electrical stimulation signal. In one example, a system includes a stimulation generator configured to deliver a stimulation pulse to a patient, sensing circuitry configured to sense an evoked compound action potential (ECAP) signal evoked from the stimulation pulse, and processing circuitry. The processing circuitry may be configured to determine a maximum value of a derivative of the ECAP signal, determine a minimum value of the derivative of the ECAP signal, determine, based on the maximum value of the derivative and the minimum value of the derivative, a characteristic value of the ECAP signal, and determine, based on the characteristic value of the ECAP signal, at least one parameter value at least partially defining electrical stimulation therapy to be delivered to the patient.

Abstract: An example medical device includes a battery configured to provide power to the medical device and stimulation circuitry configured to generate an electrical stimulation signal. The medical device includes hibernation control circuitry configured to cause the medical device to enter a hibernation mode in response to a hibernation trigger and exit the hibernation mode in response to a wake-up trigger. The medical device includes a switch configured to open in response to the hibernation control circuitry causing the medical device to enter a hibernation mode and close in response to the hibernation control circuitry causing the medical device to exit the hibernation mode and isolation interface circuitry configured to prevent power leakage from the hibernation control circuitry to the stimulation circuitry when the medical device is in hibernation mode. The stimulation circuitry is not powered by the battery when the medical device is in the hibernation mode.

Abstract: Techniques are described for real-time phase detection. For the phase detection, a signal is correlated with a frequency component of a frequency band whose phase is being detected, and the correlation includes predominantly decreasing weighting of past portions of the signals.

Abstract: This disclosure is directed to the synchronization of clocks of a secondary implantable medical device (IMD) to a clock of a primary IMD. The secondary IMD includes a communications clock. The communications clock may be synchronized based on at least one received communications pulse. The secondary IMD further includes a general purpose clock different than the communications clock. The general purpose clock may be synchronized based on at least one received power pulse. The communications clock may also be synchronized based on the at least one received power pulse.
