Abstract: Techniques for minimizing rate of depletion of a non-rechargeable power source, to extend the operational lifetime of an implantable medical device that includes the non-rechargeable power source, by enforcing operational-mode-specific communication protocols whereby inter-device communication between the implantable medical device and another implantable medical device is such that level of power draw from the non-rechargeable power source by the implantable medical device is less than level of power draw from the rechargeable power source by the another implantable medical device for the implantable medical devices to engage in communication with each other.

Abstract: A system for sensing physiological traits of a maternal patient and a fetal patient carried by the maternal patient during a pregnancy using one or more sensors. The system may use the physiological traits sensed to define a maternal attribute for the maternal patient and a fetal attribute for the fetal patient, such as a heart rate, blood pressure, respiration rate, temperature, oxygen saturation level, or other attributes. The system is configured to compare the maternal attribute to a maternal limit describing a threshold for the maternal patient and/or compare the fetal attribute to a fetal limit describing a threshold for the fetal patient. The system is configured to issue a communication to the maternal patient and/or a clinician based on the comparisons. In examples, the system regularly communicates the maternal attribute and/or the fetal attribute to an output device of the maternal patient and/or a clinician.

Abstract: A method of detecting sleep apnea includes generating a cardiac signal indicating activity of a heart of a patient. The method further includes determining a short-term average heart rate and a long-term average heart rate. The method further includes determining a start and end of a heart rate cycle based on the short-term average heart rate and the long-term average heart rate. The method further includes determining physiological parameter values occurring during the heart rate cycle. The method further includes determining whether patient has or has not experienced a sleep apnea event based on whether one or more conditions are satisfied by one or more parameter values for one or more heart rate cycles and responsively generating an indication that patient has or has not experienced a sleep apnea event.

Abstract: An intracardiac ventricular pacemaker is configured to detect a ventricular diastolic event from a motion signal received by a pacemaker control circuit from a motion sensor. The control circuit starts an atrial refractory period having an expiration time set based on a time of the detection of the ventricular diastolic event. The control circuit detects an atrial systolic event from the motion signal after expiration of the atrial refractory period and controls a pulse generator of the pacemaker to deliver a pacing pulse to a ventricle of a patient's heart at a first atrioventricular pacing time interval after the atrial systolic event detection.

Abstract: A method of cooling a mammal with an implantable blood pump. The method includes measuring a temperature of an internal controller, the internal controller being in communication with the implantable blood pump. an alert is generated if the temperature of the internal controller exceeds a predetermined temperature threshold.

Abstract: An intracardiac pacemaker system is configured to produce physiological atrial event signals by a sensing circuit of a ventricular intracardiac pacemaker and select a first atrial event input as the physiological atrial event signals. The ventricular intracardiac pacemaker detects atrial events from the selected first atrial event input, determines if input switching criteria are met, and switches from the first atrial event input to a second atrial event input in response to the input switching criteria being met. The second atrial event input includes broadcast atrial event signals produced by a second implantable medical device and received by the ventricular intracardiac pacemaker.

Abstract: Provided is a method, system and/or apparatus for determining prospective heart failure event risk. Acquired from a device memory are a heart failure patient's current and preceding risk assessment periods. Counting detected data observations in the current risk assessment period for a current risk assessment total amount and counting detected data observations in the preceding risk assessment period for a preceding risk assessment period total amount. Associating the current risk assessment and preceding risk assessment total amounts with a lookup table to acquire prospective risk of heart failure (HF) event for the preceding risk assessment period and the current risk assessment period. Employing weighted sums of the prospective risk of the HF event for the preceding risk assessment period and the current risk assessment period to calculate a weighted prospective risk of the HF event for a patient. Displaying on a graphical user interface the weighted prospective risk of the HF event for the patient.

Abstract: Medical devices and methods for providing breathing therapy (e.g., for treating heart failure, hypertension, etc.) may determine at least the inspiration phase of one or more breathing cycles based on the monitored physiological parameters and control delivery of a plurality of breathing therapy sessions (e.g., each of the breathing therapy sessions may be provided during a defined time period). Further, each of the plurality of breathing therapy sessions may include delivering stimulation after the start of the inspiration phase of each of a plurality of breathing cycles to prolong diaphragm contraction during the breathing cycle.
