Abstract: A system for monitoring a patient includes one or more processors and a sensor device implemented in circuitry. The system is configured to measure, using the sensor device, an impedance of tissue of the patient and determine, using one or more processors, a physiological parameter comprising at least one of a heart rate, cardiac output, vascular tone, perfusion level, fluid status, respiration effort, or respiration rate of the patient based on the impedance of the tissue of the patient. The system is configured to facilitate therapy, using the one or more processors, based on the determined physiological parameter.

Abstract: Techniques are disclosed for using a rate of wireless telemetry of an implantable medical device (IMD) to estimate a remaining longevity of a power source of the IMD. For example, the IMD sets a timer indicative of a remaining power capacity of the power source until a recommended replacement time (RRT) threshold. The IMD determines a power consumption of the IMD due to telemetry and updates, based on the power consumption of the IMD due to telemetry, the timer indicative of the remaining power capacity of the power source. The IMD determines, based on expiration of the timer indicative of the remaining power capacity of the power source, that the power source has reached the RRT threshold. In some examples, the IMD may output, to an external device and for display to a user, an indication that the power source has reached the RRT threshold.

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: This disclosure is directed to devices, systems, and techniques for establishing a secure connection between two or more devices. In some examples, a device is configured for wireless communication. The device comprises signal reception circuitry configured to receive communications transmitted according to at least a first communication protocol, communication circuitry configured for wireless communication according to at least a second communication protocol, and processing circuitry electrically coupled to the signal reception circuitry and the communication circuitry. The processing circuitry is configured to receive, via the signal reception circuitry, a first signal according to the first communication protocol. In response to receiving the first signal, the processing circuitry is further configured to transmit, via the communication circuitry, a second signal according to the second communication protocol and establish a secure link according to the second communication protocol.

Abstract: An implantable medical device (IMD) automatically determines at least a portion of the parameters and, in some instances all of the parameters, of an exposure operating mode based on stored information regarding sensed physiological events or therapy provided over a predetermined period of time. The IMD may configure itself to operate in accordance with the automatically determined parameters of the exposure operating mode in response to detecting a disruptive energy field. Alternatively, the IMD may provide the automatically determined parameters of the exposure operating mode to a physician as suggested or recommended parameters for the exposure operating mode. In other instances, the automatically determined parameters may be compared to parameters received manually via telemetry and, if differences exist or occur, a physician or patient may be notified and/or the manual parameters may be overridden by the automatically determined parameters.
