Abstract: Systems and methods for treating a patient with dyspnea are disclosed. A method in accordance with a particular embodiment includes identifying the patient as suffering from dyspnea, and, based at least in part on identifying the patient as suffering from dyspnea, implanting an electrical signal delivery element within the patient in signal communication with an afferent neural pathway of a carotid body chemoreceptor. The method can further include at least reducing dyspneic sensations in the patient by directing an electrical signal from the electrical signal delivery element to the neural pathway to at least partially block afferent signals from the chemoreceptor.

Abstract: A pacing monitoring system is described for incorporation in an implantable pacemaker that monitors the pacing rate and/or cumulative pace count in order to protect a patient from excessive pacing. The system includes monitoring circuitry that is configured to operate in multiple monitoring zones, where each zone is adapted to prevent excessively high-rate pacing during a particular mode of device operation.

Abstract: Embodiments herein generally relate to implantable medical devices and, specifically, to a system and method for providing fault tolerant processing in an implantable medical device. In an embodiment a system for providing fault tolerant processing in an implantable medical device is provided. The system can include an implantable medical device comprising a processor and memory store configured to execute a plurality of threads, temporal and spatial constraints assigned to one or more of the threads, and a kernel. The kernel can include a scheduler and a thread monitor configured to monitor execution of threads against the temporal and spatial constraints, and further configured to issue a response upon violation of either of the constraints by one of the plurality of threads. In an embodiment a method for providing fault tolerant processing in an implantable medical device is provided. Other embodiments are also included herein.

Abstract: A system and method is disclosed for system fault recovery by an implantable medical device which employs a global fault response. The system enables the device to consistently recover from transient faults while maintaining a history of the reason for the device fault. Upon detection of a fault, the primary controller of the device signals a reset controller which then issues a reset command. All sub-systems of the primary device controller are then reset together rather than resetting individual sub-systems independently to ensure deterministic behavior.

Abstract: The present disclosure is directed generally to systems and methods for relieving dyspnea. A method in accordance with a particular embodiment includes receiving an input signal from a patient sensor, the input signal corresponding to an indication of the patient's breathing. The method can further include, based at least in part on the input signal, at least reducing the patient's sensation of dyspnea by delivering electrical stimulation to at least one electrode, the at least one electrode being positioned in signal communication with at least one of the patient's inspiratory muscles, expiratory muscles, afferent neural pathways of the inspiratory muscles, and afferent neural pathways of the expiratory muscles.

Abstract: A system and method is disclosed by which an implantable cardiac device may deliver tachyarrhythmia therapy in the event of a system fault. A hardware-based safety core provides the logic circuitry for detecting tachyarrhythmias and delivering shock therapy in the event of a fault which disables operation of the device's primary control circuitry. The safety core defibrillator eliminates common mode failure of the primary control circuits used in the primary defibrillator system. Failures in the primary controller memory or execution will activate the safety core defibrillator.

Abstract: A system and method is disclosed by which an implantable cardiac device may deliver bradycardia therapy in the event of a system fault. A hardware-based safety core provides the logic circuitry for delivering bradycardia therapy in the form of synchronous pacing in the event of a fault which disables operation of the device's primary control circuitry. The safety core pacemaker eliminates common mode failure of the primary control circuits used in the primary pacing system. Failures in the primary controller memory or execution will activate the safety core pacemaker.
