    Abstract: Devices and methods provide for the sensing of physiological signals during stimulation therapy by preventing stimulation waveform artifacts from being passed through to the amplification of the sensed physiological signal. Thus, the sensing amplifier is not adversely affected by the stimulation waveform and can provide for successful sensing of physiological signals. A common mode voltage is applied to the stimulation electrodes while sensing during a recharge period where the common mode voltage approximates the stimulation pulse being received at the sensing electrodes. This common mode voltage is determined based on measuring a common mode signal for at least one of the inputs of the amplifier or by deriving the proper common mode from monitoring the output signal of the amplifier to observe the elimination of artifacts during stimulation. Blanking switches may be used to blank the sensing of the peak of the recharge period should that peak be relatively large.

    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: In some examples, one or more processors determine characteristics of frequency components of a sensed bioelectrical signal. In response to determining the characteristics, the one or more processors determine therapy parameters for frequency components of a stimulation signal. The one or more processors may determine the therapy parameters based on the characteristics of the frequency components of the sensed bioelectrical signal. As another example, the one or more processors may determine the therapy parameters based on received information after the characteristics of the frequency components of the sensed bioelectrical signal are displayed to a user.

    Abstract: A subthreshold lead impedance technique is described for an implantable medical device. The lead impedance technique may be applicable to a subcutaneous implantable cardioversion defibrillator device and utilizes an output circuit of the device coupled between a first diode and a second diode to define a current path through two electrodes coupled to the output circuit. The second diode is further coupled to a switch to provide a current pathway from the first diode to circuit ground. A control circuit is coupled to the output circuit, the first diode, the second diode, and the switch to bias a leg of the output circuit in a conducting state while biasing the other legs of the output circuit in a non-conducting state.
