  • Patent number: 10426966
    Abstract: In some embodiments, a wearable cardioverter defibrillator (“WCD”) system may output a closing human-perceptible indication, after detecting a shockable cardiac arrhythmia, and after further determining that it will not shock. This may succeed in informing the patient that the WCD system will not deliver a shock responsive to the cardiac arrhythmia, which may have just self-terminated. The information may give comfort to the patient who may be conscious, and may recognize that his or her ventricular tachycardia has self-terminated. Moreover, the patient will know that he or she will not be unnecessarily shocked while conscious, and will not even need to press a cancel switch.

  • Patent number: 10426405
    Abstract: In some examples, cardiac cycle detection may be used as a more or less default approach to cardiac activity tracking. Additional rate measurement relying on different sources or analyses may require extra power consumption over the cycle detection methods. Therefore, new methods and devices are disclosed that selectively activate a second cardiac rate measurement when needed. In some illustrative methods and devices, decisions are made as to whether and which previously collected data, if any, is to be discarded, replaced, or corrected upon activation of the second cardiac rate measurement.

  • Patent number: 10420702
    Abstract: Devices, systems, software and methods for CPR quality assessment. Patient data is received, derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. In some embodiments, a penalty value can be determined for at least one of the pauses, from at least one control factor unrelated to a constant linear dependence on the pause duration. An indicative value can be derived from the penalty value. In some embodiments, at least some of the pauses are classified in one or more pause groups, depending on how well they meet one or more classification criteria. The indicative value can be derived for one of the pause groups. The indicative value can be output, and/or an alarm can be emitted if it exceeds a threshold.

  • Patent number: 10307594
    Abstract: Front-end analog circuitry is described based on a sink-regulated H-bridge topology for delivery of biphasic stimulus signals that may be useful in neurostimulation. Stimulus current may be supplied using fully-integrated dynamic voltage supplies (DVSs), which may be controlled in closed-loop to have an output voltage approximately equal to the voltage of the electrode each supplies stimulus to. The stimulus waveform may be regulated by a single, low-voltage current-digital-to-analog converter (current-DAC), which can safely interface with the electrodes (which may be at high voltages) via high-voltage adapter (HVA) circuits. Example analog front-end circuitry may utilize the balancing stimulus current to discharge the electrode-tissue interface impedance (ZE). In some examples, only after full (or sufficient) ZE discharge has been detected is a DVS used to supply the remaining balancing stimulus.

  • Patent number: 10213613
    Abstract: An external defibrillator system is disclosed that generates and applies a diagnostic signal to the patient in conjunction with defibrillation therapy. The diagnostic signal is designed to elicit a physiologic response from the patient's heart, namely, mechanical cardiac response and electrical cardiac response, electrical cardiac response only, or no cardiac response. Depending upon the type of cardiac response detected, the system selects an appropriate resuscitation protocol that considers the likely responsiveness of the patient to defibrillation therapy. In one practical embodiment, a stimulus signal is applied to patients that show mechanical and electrical capture in response to the diagnostic signal. The stimulus signal maintains the mechanical capture (and, therefore, perfusion) for a period of time prior to the delivery of a defibrillation pulse.

In operation, the profile manager (50) manages a compilation of clinical usage profiles (60), each clinical usage profile (60) being derived from a different clinical usage of the advanced defibrillator (10) for the patient, and configures the therapy manager (30) and the monitor manager (40) responsive to a selection by a user of the advanced defibrillator (10) of one of the plurality of clinical usage profiles (60). Each clinical usage profile (60) includes a therapy profile (61) specifying a configuration of the therapy manager (30) for a delivery of an electric therapy to the patient. Each clinical usage profile (60) further includes a monitoring profile (62) specifying a configuration of the monitor manager (40) for a measuring of vital parameter(s) of the patient.

  • Patent number: 10195420
    Abstract: A method and system for the diagnosis of anomalies in a lead attached to an implantable medical device, such as an implantable cardioverter defibrillator (ICD), including an insulation breach resulting in a short circuit of the high-voltage shock pulse. Determination that the defibrillation pathway is shorted may be made by initial analysis of a Reference EGM and Diagnostic EGM and subsequent analysis of Differential Diagnostic EGMs. Upon determining if a specific defibrillation pathway is shorted, the nonessential defibrillation electrode of that pathway may be excluded from the defibrillation circuit, delivering defibrillation current only between functioning defibrillation electrodes. Alternatively, the ICD system can confirm the presence of a lead anomaly with one or more alternative diagnostic approaches. Patient and remote-monitoring alerts may be initiated.

  • Patent number: 10195451
    Abstract: A medical device for caring for a patient includes a patient utility for measuring a patient parameter or administering a therapy to the patient and an alarm system that has a receiver to accept status information about the medical device. A use detector of the alarm system is structured to determine when the medical device is being prepared for use and a status detector of the alarm system is adapted to determine from the status information that the medical device is in a ready state. The alarm system further includes an alarm that is activated when the medical device is both being prepared for use and not in the ready state. This description also includes methods of generating an alarm when the medical device is both being prepared for use and not in the ready state.

  • Patent number: 10183171
    Abstract: The present invention is directed toward a detection architecture for use in implantable cardiac rhythm devices. The detection architecture of the present invention provides methods and devices for discriminating between arrhythmias. Moreover, by exploiting the enhanced specificity in the origin of the identified arrhythmia, the detection architecture can better discriminate between rhythms appropriate for device therapy and those that are not.

  • Patent number: 10159846
    Abstract: A defibrillator system optimizes the timing and manner of applying a defibrillator charge to a patient based upon data provided to the defibrillator from a utility module or one or more external devices. A parameter module on the utility module provides the defibrillator with patient parameter information. Devices external to the utility module may provide the utility module with coaching data that the utility module may pass through to the defibrillator as a proxy to the external devices. The utility module may also provide external devices with patient data that the utility module may pass through to the external devices as a proxy to the defibrillator on a scheduled or other basis. The utility module may additionally provide a reserve of power to enable defibrillators to be used where power is unavailable and to enable defibrillators to deliver multiple charges more readily anywhere, anytime.

  • Patent number: 10155120
    Abstract: Methods and systems that analyze electrocardiogram (ECG) data to identify whether it would be beneficial for a caregiver to administer an electric shock to the heart in an effort to get the heart back into a normal pattern and a consistent, strong beat. By conducting a running check for conditions that are pre-validated by a comprehensive patient database to have high predictive value (e.g., with a low false-positive rate), a shockable rhythm can be identified fast (e.g., less than 6 seconds, less than 3 seconds, possibly in less than a second) and without having to analyze ECG data for longer time segments than would otherwise be required using conventional methods.
