Abstract: Techniques for switching an implantable medical device (IMD) from a first mode to a second mode in relation to signals obtained from internal sensors are described. The internal sensors may include a temperature sensor and a biosensor. In some examples, processing circuitry of the IMD may make a first preliminary determination that the IMD is implanted based on a first signal from the temperature sensor. In response to the first preliminary determination being that the IMD is implanted, the processing circuitry may make a second preliminary determination that the IMD is implanted based on a second signal from the biosensor. The processing circuitry may switch the IMD from a first mode to a second mode based on both the first preliminary determination and the second preliminary determination being that the IMD is implanted.

Abstract: This disclosure is directed to techniques for detecting and mitigating inaccurate sensing in a medical system. In some examples, one or more sensors of the medical system may include at least one electrode configured to sense an impedance of a portion of a patient's body proximate to the electrode and processing circuitry of the medical system may detect an inaccuracy in the data corresponding to the one or more patient physiological parameters based upon data including at least the sensed impedance of the portion of the patient body; correct at least a portion of the inaccuracy in the data corresponding to the one or more patient physiological parameters; and generate, for display on a display device, output data indicating the inaccuracy in the data corresponding to the one or more patient physiological parameters.

Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

Abstract: A medical device is configured to generate an acceleration signal and a temperature signal. The device is configured to determine an activity metric from the acceleration signal that is representative of patient physical activity. In response to determining that the activity metric is equal to or greater than a previously determined activity metric, the device is configured to adjust a target cardiac pacing rate based at least on a temperature change determined from the temperature signal. The device may include a pulse generator for generating cardiac pacing pulses based on the target cardiac pacing rate.

Abstract: In some examples, the disclosure describes devices, systems, and methods for determining settings of a second implantable medical device (IMD) based on patient information stored in a first IMD. The first IMD may be a device already implanted in a patient and a clinician may remove and replace the first IMD with the second IMD. The second IMD may include may be an upgrade over the first IMD (e.g., the second IMD is of the same device type but of a different model as the first IMD), may be an update to the first IMD (e.g., the second IMD is the same device type and model as the first IMD but includes different features), and/or a different device type than the first IMD.
