    Abstract: A defibrillator such as an automated external defibrillator (AED) includes a manual override feature which enables the AED to reduce the power consumption and owner annoyance after a self-testing fault. The AED, upon sensing a press of a manual override button or a receipt of an acknowledgement signal from a remote service provider, defers one or both of an alarm output and a subsequent self-test for a predetermined correction period. The deferral allows the user to correct the self-test fault during the correction period without further annoyance.

  • Patent number: 11116971
    Abstract: It has been discovered that pain felt in a given region of the body can be treated by stimulating a peripheral nerve at a therapeutically effective distance from the region where pain is felt to generate a comfortable sensation (i.e., paresthesia) overlapping the regions of pain. A method has been developed to reduce pain in a painful region following limb joint replacement by stimulating a peripheral nerve innervating the painful region with an electrode inserted into tissue and spaced from the peripheral nerve. This method may be used to help alleviate postoperative pain in patients following total knee arthroplasty surgery or other limb joint replacement surgeries.

  • Patent number: 10981014
    Abstract: Dual sequential defibrillation (DSD) systems and methods include the use of a timing device. The timing device can assist a user with DSD administration by providing notifications spaced apart by the inter-shock timing. The user can use these notifications to trigger the administration of defibrillation in a sequential manner. The timing device can also be coupled to two defibrillation devices and can output a signal to each of the defibrillation devices to cause the defibrillation device to administer a defibrillation. The output of the signals by the timing device can be spaced apart by the inter-shock timing. Additionally, the signals can be QRS-like in nature to cause the defibrillation devices to administer a defibrillation when in a sync mode.

  • Patent number: 10963129
    Abstract: The present disclosure generally relates to managing user interfaces associated with physical activities. The user interface displays a scrollable list of affordances associated with physical activities. The affordances may contain physical activity and heart rate information. A user can launch a physical activity tracking function or an interface to change a workout metric using an affordance. Users can also control the music that is played in response to selecting a workout. Further, the interface can be used to compose a reply message to a received message that contains workout information. The interfaces can show a graph that includes heart data when the user's heart rate meets a heart rate alert criteria.

  • Patent number: 10960213
    Abstract: Ambulatory medical devices may occasionally improperly administer a therapeutic stimulation pulse to a patient upon an incorrect detection of arrhythmia in the patient. To address these improperly administered therapeutic stimulation pulses, an ambulatory medical device includes processes and systems for verifying an initial declaration of an arrhythmia. The ambulatory medical device described include at least one first sensing electrode and at least one second sensing electrode distinct from the at least one first sensing electrode. First electrocardiogram (ECG) signals detected by the first sensing electrode are analyzed to provide an initial declaration of the arrhythmia condition of the patient. As a treatment protocol is being initiated in response to the analysis of the first ECG signals, second ECG signals detected by the second sensing electrode are analyzed to verify the initial declaration of the arrhythmia.

  • Patent number: 10940323
    Abstract: A Wearable Cardioverter Defibrillator (WCD) system has a processor that performs two different analyses to an ECG of the patient. A first-level analysis can be computationally economical, while a fuller second-level analysis can give shock/no-shock advice with more certainty. In some of these embodiments the second-level analysis of the ECG is performed only if the first-level analysis of the ECG detects a possible shockable condition. As such, the first-level analysis may operate as a gatekeeping function, often preventing the more computationally intensive second-level analysis from being performed. An advantage can be that the WCD system needs to store less charge, for powering the processor. In turn, this permits portions of the WCD system to be less bulky and weigh less.

  • Patent number: 10933238
    Abstract: A power control circuit for use with devices that will be placed in a flammable sterilizing gas includes a bi-stable switch that is configured to produce an output to place the circuitry of a connected device in a run state or a sleep state. The bi-stable switch controls one or more transistors to drain energy from energy storage devices in the circuitry of the connected device to a level below an ignition level of a sterilizing gas. A remotely actuatable switch can be actuated from outside of a packaging in which the power control circuit is placed to cause the bi-stable switch to produce an output that puts the circuitry in the run state without removing the power control circuit from the packaging.

  • Patent number: 10926097
    Abstract: Techniques are described for providing a therapeutic pseudo-constant DC current in an implantable stimulator using pulses whose positive and negative phases are not charge balanced. Such charge imbalanced pulses act to charge any capacitance in the current path between selected electrode nodes, such as the DC-blocking capacitors and/or any inherent capacitance such as those present at the electrode/tissue interface. These charged capacitances act during quiet periods between the pulses to induce a pseudo-constant DC current. Beneficially, these DC currents can be small enough to stay within charge density limits and hence not corrode the electrode or cause tissue damage, and further can be controlled to stay within such limits or for other reasons. Graphical user interface (GUI) aspects for generating the charge imbalanced pulses and for determining and/or controlling the pseudo-constant DC current are also provided.

  • Patent number: 10926099
    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: 10905892
    Abstract: A smart carry case which is effectively a portable GPS-enabled, AED monitoring system that is capable of monitoring an AED (as well as itself) and reporting back the presence, function and location of the AED to a remote host. Also disclosed is street furniture that is configured to retain, continuously monitor, and dispense an AED and communicate to a remote host (i.e., a control room). The street furniture is preferably configured such that a user presses the intercom button. In response, the street furniture contacts the control room. The control room, in turn, sends a signal to the street furniture causing the compartment to unlock so the AED can be removed and used in a rescue. The street furniture is configured to continuously monitor the AED and ensure it is functional, using a device such as has been described hereinabove. If the AED is used, an ambulance is deployed to the location. The AED that is retained in the compartment may be a smart carry case.
